1 Overview Introduction You use the DP/ASi link to interface the Actuator Sensor Interface to the PROFIBUS-DP. Devices and modules The DP/ASi link operates as a DP slave and requires a DP master – for example, an IM 308-C. In this chapter In Section Distributed I/O System DP/ASi Link EWA 4NEB 710 6055-02b You Will Find on Page 1.1 Using the DP/ASi Link 1-2 1.2 What is the DP/ASi Link? 1-3 1.
Overview 1.1 Using the DP/ASi Link Definition The DP/ASi link connects the Actuator Sensor Interface (referred to in the following as ASi) to the PROFIBUS-DP. PROFIBUS-DP conforms to the PROFIBUS-DP standard EN 50170 Volume 2, PROFIBUS; the term DP means ”distributed I/O”. You will find an explanation of how the ASi works in Chapter 2.
Overview 1.2 What is the DP/ASi Link? Definition The DP/ASi link connects the actuator sensor interface (ASi) to the PROFIBUS-DP field bus. In doing so, the protocols of the bus systems are converted. Overview The DP/ASi link belongs to the Distributed I/O. The DP/ASi link is a DP slave. In addition, other components belong to the DP/ASi link.
Overview Connections – PROFIBUS-DP – ASi cable – 24 V DC power supply Optical isolation between PROFIBUS-DP and ASi Direct ET 200 Handheld connection possible for setting the station number (using an adapter cable) ASi diagnostics using LEDs The diagnosis can also be read using the DP master.
Overview 1.3 View of the DP/ASi Link View Fig. 1-3 contains an illustration of the DP/ASi link. You will find detailed descriptions of the different areas of the DP/ASi link in Chapter 4.

2 ASi Basics Introduction If you wish to acquire a general idea of ASi, this is the right chapter for you. If you are already familiar with ASi, you can skip this chapter. Definition The Actuator Sensor Interface is a wiring system to which a master and up to 31 slaves can be connected. The ASi master (the DP/ASi link) periodically transfers input and output data from and to all the ASi slaves within a period not exceeding 5 ms.
ASi Basics 2.1 Structure of ASi Structure You can install the ASi as branched with a single 2-wire cable. You connect the DP/ASi link, the different ASi slaves and the ASi power supply unit to any point on the ASi cable. Example installation Fig. 2-1 shows an example installation of an ASi. a b c d Connection of DP/ASi link by means of ASi cable Remote ASi slave with external power supply unit ASi with star termination You can also connect the ASi power supply unit directly to an ASi slave.
ASi Basics 2.2 Elements of ASi DP/ASi link The DP/ASi link is the ASi master. It controls communication in the ASi. The DP/ASi link periodically exchanges data with the ASi slaves. ASi slave ASi slaves are the input and output channels of the ASi. ASi slaves transfer data to the DP/ASi link when requested to do so by the DP/ASi link. ASi slaves are: Modules You connect up to 4 binary actuators and sensors to a single module.
ASi Basics ASi distribution unit You use the ASi distribution unit when you branch the ASi cable without using an ASi slave reroute the ASi cable to a normal 2-wire cable. The ASi distribution unit is designed as a module and is not assigned an ASi address. ASi cable You connect the different elements via an ASi cable that is protected against polarity reversal. Within the ASi, you can branch the ASi cable over a total length of up to 100 m.
ASi Basics 2.3 Example Configuration of a Module Module configuration Every module consists of an upper part and a lower part. As an example, you can see an illustration in Fig. 2-2 of an upper part with two inputs and two outputs and a lower part for the ASi cable without an interface for an external power supply. The upper part is attached to the lower part with four attaching screws (see remark g).
ASi Basics 2.4 Connecting Elements Connecting You connect the elements of the ASi by attaching the modules to the ASi cable. You do not have to operate the ASi cable for this. The ASi cable is connected to the DP/ASi link by means of a connector. Penetration technique In section 2.3, Fig. 2-2, you can see an illustration of an example of a module. You place the ASi cable in the module lower part.
ASi Basics 2.5 Interruption or Short-Circuit of the ASi cable ASi short-circuit If the ASi cable is short-circuited due to pinching or fraying of the insulation, data exchange no longer takes place on the ASi cable. ASi interruption If the ASi cable is interrupted, you can no longer address the actuators or sensors which, as viewed from the DP/ASi link, are located downstream of the point of interruption. The actuators and sensors upstream of the point of interruption are still able to operate.

3 Configuration Options Introduction At this point we will show you how you integrate the DP/ASi link into the PROFIBUS-DP, and what you have to bear in mind when you do so. The power supply (PS) described in this chapter is the 24 VDC power supply of the DP/ASi link, which is required to operate it. Tip If you are already familiar with the configuration options of the PROFIBUSDP – for example, from the Distributed I/O System ET 200C manual, you can skip this chapter.
Configuration Options 3.1 Summary of Configuration Options Configuration options Table 3-1 PROFIBUS-DP presents you with different configuration options for combining the PROFIBUS-DP and the 24 V power supply of the devices. The following Table 3-1 shows the different options.
Configuration Options 3.2 Configuration without T Connector and with Power Supply Connector Definition In a configuration with a looped-through field bus and a power supply, the DP/ASi link is connected directly to the PROFIBUS-DP. The power supply is gated by means of the power supply connector with the PROFIBUS-DP in a single cable. Advantage You do not require a T connector. The power supply is fed along the bus cable, i.e. an external power supply of the slave station is not required.
Configuration Options 3.3 Configuration with T Connector and with Power Supply Connector Definition In a configuration with a power supply connector and a T connector, the DP/ ASi link is connected by means of a T connector to the PROFIBUS-DP. The power supply is gated by means of the power supply connector with the PROFIBUS-DP in a single cable. Advantage A slave station can be disconnected at any time from the bus without the ”bus traffic” being interrupted for the other slave stations.
Configuration Options Rules for the T connector With the DP/ASi link, spur lines are not authorized except for the programmer or the ET 200 Handheld. This means that the 12-pin plug of the T connector is always screwed directly to the bus connection of a module.
Configuration Options 3.4 Configuration with Several Power Supply Connectors Constraint for installation with one power supply connector In configurations with a power supply connector (refer to sections 3.2 and 3.3), the power supply is fed along the bus cable.
Configuration Options 3.5 Configuration without Power Supply Connector Definition In a configuration with a separate power supply, every slave station is supplied with power separately. This power supply must not be fed on the bus cable. The T connector for connecting PROFIBUS-DP is imperative for continuous looping of the PROFIBUS-DP. Advantage You do not feed the power supply over the bus (2-core instead of a 5-core cable).
Configuration Options Rules for the T connector With the DP/ASi link, spur lines are not authorized except for the programmer or the ET 200 Handheld. This means that the 12-pin plug of the T connector is always screwed directly to the bus connection of a module.
Configuration Options 3.6 Configuration with Programmer Connector Definition If you wish to operate the programmer on the PROFIBUS-DP in an IP 66/IP 67 environment, you require a programmer connector. Connecting the programmer To connect the programmer to the programmer connector, you require two plug-in connectors: adapter cable programmer connecting cable An ET 200 Handheld cannot be connected to the programmer connector.
Configuration Options Rule for connection of programmer connector Both the 2-core cable and the 5-core cable can be connected to the programmer connector. A programmer connector may be placed anywhere on the PROFIBUS-DP field bus. When doing so, pay attention to the following: Since a terminating resistor cannot be inserted, the programmer connector must not be located at the ends of the bus line. You may place several programmer connectors on the bus.
Installing and Wiring the DP/ASi Link 4 Introduction In this chapter you will learn how the DP/ASi link is installed mechanically and electrically. Objective When you have worked your way through this chapter, you will be in a position to install and connect the DP/ASi link. You will know what accessories you require to perform these jobs. In this chapter In Section Distributed I/O System DP/ASi Link EWA 4NEB 710 6055-02b You Will Find on Page 4.1 Installation 4-2 4.
Installing and Wiring the DP/ASi Link 4.1 Installation Rules The IP 66/IP 67 degree of protection can be guaranteed for the DP/ASi link only under the following conditions: The supporting surface for the DP/ASi link must be level (without distortions). You must always cover the unused connection with the enclosed metal cap. IP 66/IP 67 is not guaranteed with the transparent transit protective cap.
Installing and Wiring the DP/ASi Link 4.2 Electrical Wiring of DP/ASi Link Introduction You can wire the 24 V supply to the DP/ASi link either as a grounded or an ungrounded installation, depending on the requirements of your system installation.
Installing and Wiring the DP/ASi Link 4.2.1 Grounded Installation Introduction With grounded installation of the DP/ASi link, you have to connect the reference potential of the electronics section to the protective conducter. Note that in this case only the power supply for the electronics (M24V) is grounded. The PROFIBUS-DP bus and the AS interface are not grounded by this action.
Installing and Wiring the DP/ASi Link Installation Grounded installation of the DP/ASi link is shown in the diagram below. L1 L2 L3 N PI (1) (2) (4) (3) L+ (5) G L+ G G PI PI 24 V PS cntr.
Installing and Wiring the DP/ASi Link 4.2.2 Ungrounded Installation Definition With ungrounded installation of the 24V supply to the DP/ASi link, there is no link between the external power supply (terminal G) and PI, thus resulting in the protective conductor loosing its protective function. Due to the internal design of the DP/ASi link, the supply voltage is connected capacitively to the protective conductor. This results in high-frequency interference being diverted.
Installing and Wiring the DP/ASi Link Installation Ungrounded installation of the DP/ASi link is shown in the diagram below. L1 L2 L3 N PI (1) (2) (3) (7) >U G L+ (5) L+ G G PI PI 24 V PS cntr.
Installing and Wiring the DP/ASi Link 4.2.3 Connecting the DP/ASi Link to ASi and PROFIBUS-DP Pinout The location of the three sockets of the DP/ASi link is described in Fig. A-1. You will find the pinout of the DP/ASi link sockets in Table 4-2 and Table 4-3. Connecting the ASi Connect the ASi cable with the special terminal. Secure the connector with the union nut. You obtain the special terminal for the ASi cable by quoting Order Number 6ES7 194-5AA00-0XA0.
Installing and Wiring the DP/ASi Link Device connector assignment You can connect either the PROFIBUS-DP or the power supply to the device connector. The two 12-pin connectors are interconnected internally. Table 4-3 shows the assignment of the 12-pin device connector.
Installing and Wiring the DP/ASi Link 4.3 Commissioning In this section In this section you will learn what you have to take into consideration to commission the DP/ASi link. Sequence You commission the DP/ASi link in several steps. Action Note Install and wire the ASi completely. Connect the ASi power supply to the ASi cable. Refer to the instructions for the different ASi slaves and modules concerned to learn how to install them.
Installing and Wiring the DP/ASi Link 4.3.1 Selecting the Station Number for PROFIBUS-DP Definition With the station number, you identify every station of the PROFIBUS-DP. The station number represents the name used by the DP master to address individual stations. Selecting station numbers With switch 8 of the DIP switch block (refer to Fig. 4-3), you define whether the station number in the EEPROM or the station number on the DIP switch block is valid.
Installing and Wiring the DP/ASi Link 4.3.2 Setting a Station Number on the DIP Switch Block Station number If you wish to use the station number of the DIP switch block, you must set the configured station number of the DP/ASi link on the DIP switch block before initial startup. DIP switch block You will find the DIP switch block under the screw-type cover on top of the DP/ASi link (refer to Fig. 4-3). Open the screw-type cover using a suitable coin.
Installing and Wiring the DP/ASi Link 4.3.3 Station Number in EEPROM Default station number The DP/ASi link is supplied to you with the default station number,126, in the EEPROM. The DIP switch block is set ex works so that the station number in the EEPROM is valid. You have to modify this station number either by using the ET 200 Handheld or by means of the DP master.
Installing and Wiring the DP/ASi Link Resetting station numbers In certain cases the station number in the EEPROM of the DP/ASi link has to be reset. Proceed in the following order: Step 4-14 Action 1 Turn off the power supply for the DP/ASi link. 2 Turn switch 8 on the DIP switch block to OFF. 3 Turn on the power supply for the DP/ASi link and then turn it off after automatic start-up of the DP/ASi link. Start-up is aborted with an error message. The station number is reset to 126.
Installing and Wiring the DP/ASi Link 4.4 Additional Components for PROFIBUS-DP Introduction In this section You require additional components to operate the DP/ASi link on the PROFIBUS-DP. You will learn what components are involved, and their characteristics, in this section.

Configuring the DP/ASi Link 5 Introduction To operate the DP/ASi link to the PROFIBUS-DP, you must configure and assign parameters to it. Method There are two ways in which you can configure a DP/ASi link: 1. You can use the STEP 7 application ( version 2.1 or higher) or COM ET 200 Windows (version 2.0 or higher). 2. You can use any external master that is not covered by COM ET 200 Windows. The simplest method is to configure the DP/ASi link using STEP 7 (version 2.1 or higher).
Configuring the DP/ASi Link In this chapter 5-2 In Section You Will Find on Page 5.1 Configuring - for Example with COM ET 200 Windows (Version 2.0 or Later) 5-3 5.2 Example Using COM ET 200 Windows (Version 2.0 or Later) 5-5 5.
Configuring the DP/ASi Link 5.1 Configuring – for Example with COM ET 200 Windows (Version 2.0 or Later) Method In the following you will find a description of the method by which you can integrate the DP/ASi link into the PROFIBUS-DP using COM ET 200 Windows (version 2.0 or later). You will find additional information about the different steps in the integrated online Help of COM ET 200 Windows. 1. Open the worksheet with the DP master to which you wish to connect the DP/ASi link. 2.
Configuring the DP/ASi Link Parameterize By choosing Parameterize..., you can influence the start-up characteristics of the DP/ASi link. You can differentiate between ”actual is equal to setpoint configuration” and ”actual is less than or equal to setpoint configuration”. Actual configuration By actual configuration we mean the actual configuration of the ASi as detected by the DP/ASi link.
Configuring the DP/ASi Link 5.2 Example Using COM ET 200 Windows (Version 2.0 or Later) Model structure You wish to connect an ASi with an ASi slave over the DP/ASi link to the PROFIBUS-DP. The ASi slave has the following assignment: S one ASi slave with 4 inputs Assign the ASi slave to the ASi address as shown in Table 5-1. Set the ASi address according to your requirements. The I/O code (refer to Appendix B) results from the input/output assignment.
Configuring the DP/ASi Link 5.3 Operating the DP/ASi Link with an External Master Introduction If you do not use an application having an easy-to-use user interface for the DP/ASi link – for example, COM ET 200 Windows (version 2.0 or later) or a comparable application, you must pay attention to the following points. In Section 5-6 You Will Find on Page 5.3.1 Configuring with Address Space Optimization 5-7 5.3.2 Simple Configuration 5-8 5.3.
Configuring the DP/ASi Link 5.3.1 Configuring with Address Space Optimization Requirement You can operate the DP/ASi link with any DP master that conforms with the DP standard and supports a parameterization message containing 140 bytes (full assignment of parameters). Basics We will confine ourselves here to showing you how to address the DP/ASi link on the PROFIBUS-DP side. Configuring Configure the DP/ASi link in the following order: Action Step Meaning 1 Define the installation of the ASi.
Configuring the DP/ASi Link 5.3.2 Simple Configuration Requirement The DP/ASi link, version 3 or later, can also be operated on DP standard masters having a reduced message length of 32 bytes (reduced parameter assignment). A DP standard master of this type is the S5-95U with its integrated DP master interface, for example. Configuring Configure the DP/ASi link in the following order: Action Step Meaning 1 Define the ASi installation.
Configuring the DP/ASi Link 5.3.3 Default Start-Up Introduction You can also configure and assign parameters to the DP/ASi link from the DP standard master by means of a ”default start-up”. In a default start-up, the DP/ASi link operates with preset parameters, which are described in detail on the next few pages. The information is important if you wish to operate the DP/ASi link on the DP standard master of a manufacturer who does not provide an easy-to-use configuring tool.
Configuring the DP/ASi Link Input and output area The table below describes the location of ASi data in the input and output area.
Configuring the DP/ASi Link Parameterization and configuration messages Following power up, the DP/ASi link determines the configuration of the AS interface and expects a parameterization message and a configuration message from the DP master. The parameterization message is identical to the first seven bytes of the DP standard part (bytes 0 to 6). You will find a detailed account of the DP standard part in appendix C.1.

6 DP/ASi Link to S7 Introduction If you operate the DP/ASi link to an S7 (6ES7 156-0AA01-0XA0 or later, version 1), you can re-assign the parameters of the ASi slaves connected to the DP/ASi link during operation. This is done on the S7 by SFCs 59 “RD_REC” and 58 “WR_REC”, which permit data records to be read and written.
DP/ASi Link to S7 Table 6-1 Parameters for SFC 59 “RD_REC”, continued Parameter Declaration Data Type Memory Area Description BUSY OUTPUT BOOL I, O, M, D, L BUSY = 1: Read operation still being processed RECORD OUTPUT ANY I, O, M, D, L Destination area for data record read Example: Data record 140 (22 bytes long) is to be stored in bit memory address area from MB 50 onward, RECORD = P#M50.0 BYTE22 SFC 58 ”WR_REC” Table 6-2 You use the SFC 58 to transfer a data record to the DP/ASi link.
DP/ASi Link to S7 6.1 Reading Data Records with SFC 59 ”RD_REC” Data record 140 Table 6-3 You use data record 140 to read lists and flags of the ASi slaves. In the case of lists, the ASi slaves present, enabled and configured are displayed. This data record also displays the version and release date of the DP/ASi link.
DP/ASi Link to S7 Data record 141 Data record 141 reads outs the parameter echoes of the different ASi slaves. You can evaluate the reactions of the different ASi slaves in a parameter echo following a “WR_REC” write job in the user program. You thus obtain a current image of the state of the ASi slaves.

7 Operating Modes Introduction The DP/ASi link goes through various operating modes during operation, ranging from automatic start-up to normal mode and automatic programming. We will briefly describe these operating modes for you. CONFIG MODE In this chapter The configuration mode, which is assigned to the CONFIG MODE LED, is provided for extensions of the SIMATIC S7. In Section Distributed I/O System DP/ASi Link EWA 4NEB 710 6055-02b You Will Find on Page 7.
Operating Modes 7.1 Automatic Start-up of DP/ASi Link Start-up behavior There are not any switches on the DP/ASi link. The DP/ASi link commences work as soon as it is connected to the power supply. The following flowchart shows the sequence of automatic startup. Step Flowchart Meaning 1 The power supply of the DP/ASi link is turned on. Start 2 The two interface controllers for the ASi and the PROFIBUS-DP are initialized. The DP/ ASi link enters a defined basic state.
Operating Modes Step Flowchart Meaning 9 The DP/ASi link, as the ASi master, periodically polls the I/O code and the ID code of all the ASi slaves possible. A 10 During the polling cycle, the DP/ASi link must detect at least one ASi slave.
Operating Modes 7.2 Normal Operation Method of operation In normal operation, the DP master exchanges data with the DP/ASi link in exactly the same manner as with any other DP slave. You do not have take any specific action. Tasks In normal operation, there is a continuous exchange of data with the ASi and the PROFIBUS-DP. The activities of the DP/ASi link can be divided into two tasks: 1. Monitor the ASi 2.
Operating Modes ASi slave failure If the connection to an ASi slave or an ASi slave fails during routine operation, undefined states may occur at the outputs. Behavior depends on the slaves concerned and the causes of failure. The input data are reset in the DP/ASi link. The input data are not updated until a cause of failure has been remedied. Note If an ASi slave fails, the data sent by the DP/ASi link to the DP master are no longer valid for to that ASi slave.
Operating Modes 7.3 Automatic Programming Definition ”Automatic programming” is an operating mode that occurs only when one ASi slave fails. Display The DP/ASi link shows you the ”automatic programming” mode using the ”AUTOPROG AV” LED. Byte 20.4 is set simultaneously in the diagnostic message. Meaning If ”automatic programming” mode is displayed, then precisely one ASi slave has failed. Furthermore, there is no ASi slave with ASi address 0 in the ASi.
Diagnostics and Error Handling 8 Introduction You use the chapter entitled ”Diagnostics and Error Handling” to evaluate the diagnosis of the DP/ASi link and to take the necessary action. Diagnostic options You have two diagnostic options which refer you to the location at which the diagnostic information is stored. Diagnosis by means of LEDs gives you the opportunity to evaluate messages and to remedy any errors which have occurred.
Diagnostics and Error Handling 8.1 Diagnostics by Means of LEDs of DP/ASi Link Diagnostics For on-site diagnostics, the operating modes of the DP/ASi link are displayed by six LEDs. Five other LEDs indicate the address of the failed ASi slave (refer to Fig. 8-1).
Diagnostics and Error Handling ASi slave address So that the DP/ASi link display is not cluttered, failed ASi slaves (ASiSLAVE FAIL) are displayed in binary code by five LEDs. You have to add the numbers shown on the lit LEDs to determine the address of the failed ASi slave. If several ASi slaves have failed, the failed ASi slave having the lowest address is indicated. In this case the ”AUTOPROG AV” LED is off. Example LEDs showing the numbers ”1”, ”)2” and ”)4” are on. Add up the numbers: 1)2)4+7.
Diagnostics and Error Handling ASi diagnostics Table 8-3 shows the meanings of the LEDs for ASi diagnostics and describes the action required to be taken for troubleshooting. For ASi diagnostics, the DP/ASi link has four LEDs. In the event of a failure, one or several LEDs are turned on. Table 8-3 LED display for faults on ASi side LED on Reason Meaning Remedy ASi POWER FAIL The ASi power supply has failed. Data exchange between the DP/ Check the ASi power supply.
Diagnostics and Error Handling Combinations Table 8-4 In addition to the different displays described in Table 8-2 and Table 8-3, combinations of several LEDs are also possible. Table 8-4 shows you the meanings of the displays. Combination of several LEDs LEDs Meaning Remedy All on DP/ASi link starting up. – All on except ASi POWER FAIL A fault has occurred in the PROFIBUS-DP during start-up. Check the PROFIBUS-DP, the DP master and the bus connection.

Diagnostics and Error Handling 8.2.1 Diagnostic Fundamentals in Operations with an IM308C FB IM308C You can read the DP/ASi link diagnosis, as the ”slave diagnosis”, using function block IM308C (FB192) into your PLC – for example, SIMATIC S5 with IM 308 C. FB IM308C is described in detail in the Distributed I/O System ET 200 manual. Exchanging diagnostic data The DP/ASi link informs the DP master, by means of a high-priority transmission of user data, that a diagnosis is available.
Diagnostics and Error Handling Example At this point you will find a brief example of how to read the slave diagnosis into your PLC using FB IM308C. The following assumptions apply to this STEP 5 program: The IM 308-C is assigned, as a PROFIBUS-DP master, pages 0 to 15 (number 0 of IM 308-C). The station number of the DP/ASi link is 3. The slave diagnosis is to be stored in DB 30. You may also use any other data block to store it in. The slave diagnosis consists of 26 bytes.
Diagnostics and Error Handling 8.2.2 Diagnostic Fundamentals in Operations with an S7/M7 DP Master (STEP 7) or with Another PROFIBUS-DP Master Diagnosis with S7/M7 DP Master If you are operating the DP/ASi link as a DP slave with a SIMATIC S7/M7 DP master, the DP/ASi link behaves like a central S7-300 I/O module. SFC 13 “DPNRM_DG” You read out the diagnosis (data records 0 and 1) using SFC 13 ”DPNRM_DG”.
Diagnostics and Error Handling 8.2.3 Structure of Diagnosis Introduction The structure of the diagnostic message conforms with the PROFIBUS-DP standard. Note The structure of the diagnostic message described below does not apply to a default start-up (refer to section 8.2.9).

C Parameterization Message Tip You require this chapter only if you are not using an application such as COM ET 200 Windows (version 2.0 or later). Introduction The DP/ASi link requires the parameterization message during start-up. This appendix describes the structure of the parameterization message for the DP/ ASi link when used as a DP standard slave. When you have studied this chapter, you can manually create the parameterization message on your own.
Parameterization Message C.1 Structure of the Parameterization Message in Configuring with Address Optimization Structure The parameterization message contains 140 bytes of data, bytes 0 to 139.
Parameterization Message Table C-1 Byte(s) Structure of the DP standard part in parameterization message, continued Value 6 Meaning Group ID You can place several DP slaves in one group with the group ID. 1 Station status Refer to Table C-3 for the watchdog time base The station status defines the operating behavior of the DP/ASi link as a DP slave.
Parameterization Message Initialization bytes Bytes 7 to 14 are referred to as the initialization bytes.
Parameterization Message Actual less than or equal to setpoint configuration ”Actual is less than or equal to setpoint configuration” means that the DP/ ASi link compares the actual configuration with the setpoint configuration. If the DP/ASi link detects any differences, it reacts in two different ways: If the DP/ASi link detects unconfigured ASi slaves, it behaves in the same way as for ”actual is equal to setpoint configuration”.
Parameterization Message C.2 Parameterization Data for ASi Slaves Structure Table C-6 You have to define four bytes for every ASi slave when you assign parameters. These four bytes contain all the data required for an ASi slave and data exchange with it. You will find the structure of these four bytes for every ASi slave in Table C-6.
Parameterization Message Address assignment In Table C-7 you will find the assignment of the ASi addresses to the byte numbers within the parameterization message. Table C-7 Example Assignment of parameterization data of ASi slaves to byte numbers of parameterization message Parameterization Data for ASi Slave with ASi Address ...
Parameterization Message C.3 Optimizing Address Assignment Purpose For you to be able to address the ASi slaves, you have to allocate the address assignment within the SIMATIC to every ASi slave. To make proper use of the limited address space on the SIMATIC, you must optimize the address assignment of the different slaves. Method Optimize the input address area first and then the output address area.
Parameterization Message Example Fig. C-1 illustrates the process for optimizing address assignment using the address space template. The four AS slaves used have the following input/output assignment: ASi Address Inputs Outputs 1 4 0 4 2 2 5 3 1 7 0 4 Outputs Inputs ASi slave 1 4 3 ASi slave 4 ASi slave 5 ASi slave 7 3 2 1 None 2 1 4 2 1 4 None 4 3 3 2 1 Sl. 4 Byte 1 2 Byte 0 Bit: 7 1 Slave 1 Slave 5 S5 Sl.
Parameterization Message C.4 Structure of the Parameterization Message in Simple Configuration Parameterization message structure The parameterization message has a fixed length of exactly 32 bytes. DP standard part Bytes 0 to 6 contain the parameters of the DP standard part. Table C-8 Initialization bytes Assigning the DP standard part Byte 0 1 Value Refer to Table C-1 2 3 4 5 6 Bytes 7 to 14 are referred to as the initialization bytes.
Parameterization Message Setpoint configuration Bytes 16 to 31 reflect the setpoint configuration of the DP/ASi link. An ASi slave is permanently assigned to every nibble. If an ASi slave has been configured, its hexadecimal I/O code has to be entered at this stage; unconfigured ASi slaves have to be identified by FH.

D Configuration Message Tip You require this section only if you are not using an application such as COM ET 200 Windows. Introduction The DP/ASi link requires the configuration message during start-up. This chapter describes the structure of the configuration message for the DP/ASi link used as a DP standard slave. Meaning The configuration message defines the length of input and output data. They are compared with the data contained in the parameterization message.
Configuration Message D.1 Structure of the Configuration Message with a Default Start-Up Structure The configuration message consists of precisely 20 bytes. With a default start-up, it must have the structure shown in Table 8.
Configuration Message D.2 Structure of the Configuration Message in Configuration with Address Optimization Structure The configuration message contains 20 bytes. The first 15 bytes are permanently assigned, as shown in Table D-2. All values are hexadecimal numbers.
Configuration Message Identification byte With the identification byte, you define the structure of the configuration message. You will find a description of the value of the identification byte in Table D-3. Table D-3 Value of identification byte in configuration message Value 43H Meaning Input data only in byte 16, the length byte stands for the input data there follow three bytes of manufacturer-specific data: 00H 3CH 40H, (bytes 17 to 19).
Configuration Message Example 1 The following example presents the structure of the five bytes of data (bytes 15 to 19) for a DP/ASi link with inputs and outputs.
Configuration Message Example 3 The following example shows the structure of the five bytes of data (bytes 15 to 19) for a DP/ASi link having only outputs.
Configuration Message D.3 Structure of the Configuration Message in Simple Configuration Structure The configuration message consists of 20 bytes and must have the structure shown in Table D-5. The type and length of the I/O area used are encoded in bytes 15 to 17.
Configuration Message Example of determining length IDs You have an DP/ASi link on which the ASi slave with the highest address to which outputs are connected is slave 7; the ASi slave with the highest address to which inputs are connected is slave 12. Accordingly, the output area has a length of 4 bytes, for slave 7 is located in the fourth byte. The length ID for the outputs is 03H. The input area has a length of 6 bytes, for slave 12 is located in the sixth byte. The length ID for the inputs is 05H.
Glossary A Active nodes Active nodes may send data to other nodes, if they are token holding nodes, and request data from other nodes (synonymous with master). Actual configuration By actual configuration we mean the true configuration of the ASi as detected by the DP/ASi link. ASi ActuatorSensor Interface. The Actuator Sensor Interface is a networking system for the lowest range of automation levels It is suitable for networking binary actuators and sensors.
Glossary Assign parameters To assign parameters is to pass slave parameters from the master to the slave. B Baud rate Rate at which data are transmitted; specifies the number of bits transmitted per second (baud rate = bit rate). Bit time The bit time (TBit) is the time required to transmit one bit. It is the reciprocal value of the baud rate: TBit = 1/baud rate C Configure Configure means performing the different settings for individual modules in a Distributed I/O System.
Glossary Distributed I/O devices Distributed I/O devices are I/O units that are not used in the base unit but are set up on a distributed basis; for example: ET 200 family S5-95U with PROFIBUS-DP interface DP/ASi link other DP slaves from Siemens or external devices. Distributed I/O devices are connected to the DP master over the PROFIBUSDP bus. DP DP stands for ”distributed I/O”.
Glossary ID code The ID code is an additional identification, its use being optional for each ASi slave. The ID code is specified for every ASi slave. The default value of the ID code is 0. IM 308-C The IM 308-C is a DP master for the Distributed I/O System. IP 66 Degree of protection in accordance with DIN 40050: complete protection against contact, protection against the ingress of dust and protection against the detrimental ingress of heavy seas or high-pressure hose-water.
Glossary PROFIBUS-DP Draft PROFIBUS-DP standard (EN 50170 Volume 2, PROFIBUS), on which the Distributed I/O System is based. The principal function of PROFIBUS-DP is high-speed data exchange between the central DP master and the I/O devices. PROFIBUS-DP is a bus system networking PROFIBUS-compatible programmable logic controllers and field devices at field and cell levels. PROFIBUSDP is available with DP (+Distributed I/O), FMS (+Field Bus Message Specification) or TF (+Technological Functions) protocols.
Glossary SYNC SYNC is a ³ control command of the DP master to a group of DP slaves. With the SYNC control command, the DP master causes the DP slave to freeze the outputs at their instantaneous values. In the messages that follow, the output data from the DP slave are stored but the states across the outputs remain unchanged. After every new SYNC control command, the DP slave sets the outputs with the data which it has stored as output data.
