Fast commissioning / operating principle 3 Fast commissioning / operating principle Notice! Below you will find a short description for the initial commissioning of the PROFINET gateway MA 248i. Detailed explanations for the listed points can be found throughout the handbook. 3.1 Mounting The gateway mounting plate MA 248i can be mounted in two different ways: • using four threaded holes (M6) or • using two M8x6 screws on the two lateral grooves. 3.
Fast commissioning / operating principle 3.3.1 Connecting the Leuze device To connect the Leuze device to the internal RS 232 device interface, open the housing of the MA 248i and lead the corresponding device cable (see chapter 14.6) through the middle threaded opening. Connect the cable to the internal device interface (X30, X31 or X32, see chapter 7.5.1). Use rotary switch S4 (see chapter 8.2.5) to select the connected device.
Fast commissioning / operating principle 3.5 Commissioning the MA 248i on the PROFINET Complete the necessary steps for commissioning a Siemens-S7 control as described below. Further information regarding the individual commissioning steps is provided in see chapter 12.3 "Configuration steps for a Siemens Simatic S7 control". 3.5.1 Preparing the control system In the first step, assign an IP address to the IO Controller (S7 PLC) and prepare the control for a consistent data transmission.
Fast commissioning / operating principle 3.5.3 Configuration Configure the PROFINET-IO system with the HW Config of the SIMATIC Manager by inserting the MA 248i into your project. Figure 3.2: Assignment of the device names to IP addresses Here, an IP address is assigned to a unique "device name". 3.5.4 Configuration of the modules Now select a corresponding data module for the input and output area.
Fast commissioning / operating principle Recommendation In most cases, the 4-byte module is sufficient for the output module. A larger module is needed, for example, if a BCL bar code scanner is to be configured by means of PT-sequences, or an RFID transponder is to be described. In these cases, larger data modules are usually sensible. Notice! Examples for selecting the correct data module length can be found in chapter 12.3.
Fast commissioning / operating principle 3.5.6 Configuration of the device name - device naming PROFINET-IO defines the "naming of the device" as the creation of a name-based relationship for a PROFINET-IO device. Assigning the device names to the configured IO devices Select the respective gateway MA 248i for the "device naming" based on its MAC address. The unique "device name" (which must match the participant in the HW Config) is then assigned to this participant.
Fast commissioning / operating principle MAC address - IP address -individual device name At this point, please assign an IP address (suggested by the PLC), a subnet mask and, if required, a router address, and assign this data to the named participant ("device name"). Figure 3.4: MAC address - IP address -individual device name From now on, and when programming, only the unique "device name" (max. 255 characters) is used.
Device description 4 Device description 4.1 General Information to the connector units The modular interfacing unit of the MA 2xxi family is a versatile gateway for integrating Leuze RS 232 devices (e.g., BCL 22 bar code readers, RFID devices, RFM 32, …) into the respective fieldbus. The MA 2xxi gateways are intended for use in industrial environments with a high protection class. Various device versions are available for the conventional fieldbuses.
Device description 4.3 Device construction The MA 248i modular interfacing unit is used for interconnecting Leuze devices, such as the BCL 8, BCL 22, etc., directly to the fieldbus. This is accomplished by transmitting the data from the Leuze device via an RS 232 (V.24) interface to the MA 248i where a module converts it into the fieldbus format. The data format of the RS 232 interface corresponds to the standard Leuze data format. Fieldbus MA 248i Fieldbus RS 232 (V.
Device description 4.4 Operating modes For fast commissioning, the MA 248i offers an additional operating mode, the "Service mode", in addition to the "Standard mode". In this operating mode, the Leuze device can, for example, be configured on the MA 248i and the communication can be tested on the fieldbus. To do this, you need a PC/laptop with a suitable terminal program, as BCL-Config from Leuze or similar. Service switch Select between "operation" and "service" modes with the service switch.
Device description Service interface The service interface can be accessed once the MA 248i housing cover has been removed and features a 9-pin Sub-D connector (male). A crossed RS 232 connection cable is required to make the RxD, TxD and GND connections. MA 248i Service interface Figure 4.

Electrical connection 7 Electrical connection The fieldbus gateways MA 2xxi are connected using variously coded M12 connectors. An RS 232 device interface allows the respective devices to be connected with system connectors. The device cables are equipped with a prefabricated PG cable gland. Coding varies and the design is implemented as either socket or connector depending on the HOST (fieldbus) interface and function.
Electrical connection 7.2 Electrical connection The MA 248i features two M12 connectors/sockets for voltage supply; each is A-coded. The voltage supply (PWR IN) as well as the switching inputs/outputs (PWR OUT or PWR IN) are connected there. The number and function of the switching inputs/outputs is dependent on the connected end device. Two additional M12 sockets are used for connection to the fieldbus. Both of these connections are D-coded.

Telegram 10 Telegram 10.1 Structure of the fieldbus telegram All operations are performed by control and status bits. Two bytes of control information and two bytes of status information are available for this purpose. The control bits are a part of the output module and the status bits are a part of the input bytes. The data starts with the third byte. If the actual data length is longer than the data length configured in the gateway, only part of the data is transmitted; the remaining data is lost.

Output data Description Addr. Data type R-ACK Read-Acknowledge (read confirmation) Toggle bit: Indicates to the fieldbus gateway that the "old" data has been processed and that new data can be received. At the end of a read cycle, this bit must be toggled in order to be able to receive the next data set.
Telegram Bit 3: Copy to transmit buffer: CTB This bit is only relevant for writing slave data in blocks (Collective mode), see chapter 11.1.2. Output data Description Addr. Data type CTB Copy to transmit buffer (transmission data to transmit buffer) Toggle bit: Changing this bit writes the data from the PLC to the transmit buffer of the fieldbus gateway. This is used, for example, for long command strings which must be transmit- 1.3 ted to the connected ident device.
Modes 11 Modes 11.1 Functionality of the data exchange The fieldbus gateway has two different modes that can be selected via the PLC: • Transparent mode (standard setting) In Transparent mode, all data is sent 1:1 and directly by the serial end device to the PLC. It is not necessary to use status and control bits here. However, only data bytes possible for one transmission cycle are transmitted - all others are lost.
Modes 11.1.1 Reading slave data in Collective mode (gateway -> PLC) If the Leuze device transmits data to the fieldbus gateway, the data is stored temporarily in a buffer. The PLC is signaled via the "DEX" bit that data is ready for retrieval in the memory. Data is not automatically transmitted. If no further user data is present in the MA 2xxi ("DEX" bit = "0"), the "R-ACK" bit must be toggled once as read confirmation to release data transmission for the next read cycle.
Modes Examples for the activation of a Leuze device In the data part (starting at byte 2) of the telegram to the gateway, a "+" (ASCII) is sent for activation. This means that the hex value "2B" (corresponds to a "+") is to be entered in control or output byte 2. To deactivate the reading gate, a "2D" (hex) must be used instead (corresponds to a "-" ASCII).
Modes Collective mode sequence diagram Send long online commands to the DEV, read RS 232 answer from DEV Activate Collective mode No Select function mode in PLC via EDS file?

CTB toggle bit (control bit 1.
Modes 11.1.3 Command mode One specific feature is the so-called Command mode, which is defined via the output control byte 0 (bit 0) ... and enables the control of the connected device per bit. If the command mode is activated (command mode = 1), no data is sent by the PLC to the Leuze end device via the gateway. The data from the MA to the PLC is transmitted in the selected operating mode (Transparent/Collective).
Modes Command mode sequence diagram Set control byte 0, bit 0.0 to 1 Bit 0.0 =1?

Commissioning and configuration 12 Commissioning and configuration 12.1 Measures to be performed prior to the initial commissioning Before commissioning, familiarize yourself with the operation and configuration of the MA 248i. Before connecting the supply voltage, recheck all connections and ensure that they have been properly made. The Leuze device must be connected to the internal RS 232 device interface.
Commissioning and configuration 12.2 Starting the device Apply the supply voltage +18 … 30VDC (+24VDC model); the MA 248i starts up. 12.3 Configuration steps for a Siemens Simatic S7 control The following steps are necessary for commissioning with a Siemens S7 control: 1. 2. 3. 4. 5. 6. TNT 35/7-24V 7.
Commissioning and configuration 12.3.1 Step 1 – Preparing the control system (S7 PLC) The first step involves the assignment of an IP address to the IO Controller (PLC - S7) and the preparation of the control for consistent data transmission, see chapter 12.4.4 "Preparing the control system for consistent data transmission". Notice! If an S7 control is used, you need to ensure that Simatic-Manager Version 5.4 + service pack 5 (V5.4+SP5) or higher is used. 12.3.
Commissioning and configuration 12.3.3 Step 3 – Hardware configuration of the S7 PLC: Configuration TNT 35/7-24V For the configuration of the PROFINET-IO system using the HW Config of the SIMATIC Manager, insert the MA 248i into your project. An IP address is now assigned to a unique "device name". Figure 12.1: Assignment of the device names to IP addresses 12.3.4 Step 4 – Configuration of the modules Now select a corresponding data module for the input and output area.
Commissioning and configuration A larger module is needed, for example, if a BCL bar code scanner is to be configured by means of PT-sequences, or an RFID transponder is to be described. In these cases, larger data modules are usually sensible.
Commissioning and configuration 12.3.6 Step 6 – Configuration of the device name - naming the device The PROFINET-IO device has a unique MAC address that is part of the factory settings. You can find this address on the name plate of the gateway. This information is used to assign a unique, plant-specific device name ("NameOfStation") to the device via the "Discovery and Configuration Protocol (DCP)".
Commissioning and configuration At this point, you can select the respective gateway MA 248i for the "device naming" based on its MAC address. The unique "device name" (which must match the participant in the HW Config) is then assigned to this participant. Notice! Multiple MA 248i can be distinguished by the MAC addresses displayed. The MAC address may be found on the name plate of the respective bar code scanner.
Commissioning and configuration 12.4 Commissioning via the PROFINET-IO General information on the PROFINET implementation of the MA 248i PROFINET-IO communication profile The communication profile defines how participants serially transmit their data via the transmission medium. The PROFINET-IO communication profile is designed for efficient data exchange on the field level. The data exchange with the devices is mainly cyclical.
Commissioning and configuration 12.4.1 Modular structure of the parameter The PROFINET-IO functionality of the device is defined via parameter sets which are clustered in modules. The modules are included in a XML-based GSD file, which is supplied as an integral part of the device. By using a user-specific project tool, such as, e.g.
Commissioning and configuration 12.4.2 Permanently defined parameters/device parameters On the PROFINET-IO, parameters may be stored in modules or may be defined permanently in a PROFINET-IO participant. The permanently defined parameters are called "common" parameters or device-specific parameters, depending on the configuration tool. These parameters must always be present. They are defined outside of the configuration modules and are permanently anchored in the telegram header.
Commissioning and configuration 12.4.3 Overview of the project modules When using PROFINET-IO modules, the parameters are assembled dynamically, i.e., only the parameters that were selected by the activated modules are changed. The MA 248i has parameters (device parameters) that must always be present. These parameters are defined outside of modules and are thus linked to the base module (DAP). In the current version, several modules are available for use.
Commissioning and configuration Description Data content with max. 2 bytes Data content with max. 6 bytes Data content with max. 10 bytes Data content with max. 14 bytes Data content with max. 18 bytes Data content with max. 30 bytes Data content with max. 62 bytes Data content with max. 126 bytes Data content with max. 254 bytes Data content with max. 382 bytes Data content with max. 510 bytes Data content with max. 638 bytes Data content with max. 766 bytes Data content with max.
Commissioning and configuration The small data lengths (< 28 bytes) are particularly of interest for use with bar code scanners (BCL). The larger data lengths are, on the other hand, relevant for 2D-code scanners (handheld scanners, LSIS) and RFID. Taking into consideration the maximum permissible data width of 1024 bytes, multiple modules can also be used for the input data or combined with one another. The combination of module 128 and module 64, for example, yields an input data length of 192 bytes. 12.
Commissioning and configuration In order to communicate with the connected Leuze device, the STX, data, CR, LF framing must be set on the PC terminal program, as the Leuze device is preconfigured ex works for this frame character. STX (02h): Prefix 1 CR (0Dh): Postfix 1 LF (0Ah): Postfix 2 Operation Switch the MA 248i to switch position "RUN" (operation). The Leuze device is now connected to the fieldbus.
Commissioning and configuration 12.6.1.2 Cableless hand-held scanners on the MA 248i All wireless hand-held scanners and mobile combi devices available in the Leuze electronic product line can be used with the corresponding connection cable via the base station. A 230VAC connection (socket) is usually necessary for the charging station. Here, a data connection of the charging station is established with the MA 248i.
