Chapter 2 2. Basic Operation 2.1 General The Anybus Communicator gateway is designed to exchange data between a serial sub-network and a higher level network. Unlike most other gateway devices of similar kind, it does not have a fixed protocol for the sub-network, and can be configured to handle almost any form of serial communication. The gateway can issue serial telegrams cyclically, on change of state, or based on trigger events issued by the control system of the higher level network (i.e.
Basic Operation 13 2.2 Data Exchange Model Internally, the data exchanged on the subnetwork, and the data exchanged on the higher level network, resides in the same memory. ABC Internal Memory This means that in order to exchange data with the subnetwork, the higher level network simply reads and writes data to memory locations specified using the Anybus Configuration Manager. The very same memory locations can then be exchanged on the subnetwork.
Basic Operation 14 2.2.2 Data Exchange Example In the following example, a temperature regulator on the subnetwork exchanges information with a PLC on the higher level network, via the internal memory buffers in the Anybus Communicator.
Basic Operation 15 2.3 Subnetwork Protocol 2.3.1 Protocol Modes The Anybus Communicator features three distinct modes of operation regarding the subnetwork communication, called “Master Mode”, “DF1 Master Mode” and “Generic Data Mode”. Note that the protocol mode only specifies the basic communication model, not the actual subnetwork protocol. • Master Mode In this mode, the gateway acts as a master on the subnetwork, and the serial communication takes place in a query-response fashion.
Basic Operation 16 2.3.3 Master Mode In this mode, the communication is based on a query-response scheme; when the gateway issues a query on the subnetwork, the addressed node is expected to issue a response to that query. Nodes are not permitted to issue responses spontaneously, i.e. without first receiving a query. There is one exception to this rule; the broadcaster.
Basic Operation 17 2.3.5 DF1 Master Mode Please refer to “DF1 Protocol Mode” on page 46. Anybus Communicator PROFIBUS User Manual Doc: HMSI-27-306, Rev. 3.
Basic Operation 18 2.4 Data Representation on PROFIBUS 2.4.1 General The Anybus Communicator acts as a slave on the PROFIBUS network. As such, it does not initiate communication towards other nodes on itself, but can be read from/written to by a PROFIBUS master. 2.4.2 Data Representation The Input and Output Data areas in the internal memory buffer are represented as PROFIBUS I/O data. The amount of data exchanged on the bus depends on the configuration in the gateway.
Chapter 3 3. Navigating ACM 3.1 Main Window The main window in ACM can be divided into 4 sections as follows: A C B D • A: Drop-down Menus & Tool Bar The second drop-down menu from the left will change depending on the current context.

Chapter 4 4. Basic Settings 4.1 Fieldbus Settings (Select “Fieldbus” in the Navigation Section to gain access to the parameters described in this section). General During start-up the fieldbus interface of the gateway is initialized to fit the configuration created in the Anybus Configuration Manager. Optionally, some initialization parameters can be set manually to provide better control over how the data shall be treated by the gateway.
25 4.2 Communicator Parameters Interface Only serial communication is currently supported. Control/Status Word See “Control and Status Registers” on page 62. Value Enabled Enabled but no startup lock Disabled Description Enable the Control and Status Registers. The “Data Valid”-bit in the Control Register must be set to start the sub-network communication.
26 4.3 Sub-network Parameters Communication These parameters specify the actual communication settings used for the sub-network. Parameter Bitrate (bits/s) Description Selects the bit rate Data bits Parity Physical standard Stop bits Selects the number of data bits Selects the parity mode Selects the physical interface type Number of stop bits.
Chapter 5 5. Nodes 5.1 General In ACM, a node represents a single device on the network. Although the gateway does not feature a scan list in the traditional sense, all nodes and their transactions will be processed in the order they were defined in ACM. The maximum number of nodes that can be created in ACM is 31. 5.2 Adding & Managing Nodes Function Paste Subnetwork Monitor Add Node Add Broadcastera Load Node Subnetwork Status...
Chapter 6 6. Transactions 6.1 General As mentioned previously, transactions are representations of the actual serial telegrams exchanged on the serial sub-network. Although the gateway does not feature a scan list in the traditional sense, all nodes and their transactions will be processed in the order they were defined in ACM. Transactions are handled slightly differently in the three protocol modes: • Master Mode For regular nodes, transactions always come in pairs; a query and a response.
Transactions 29 6.2 Adding & Managing Transactions Function Copy Deletea Node Monitor Add Transaction(s)b Add Transaction Consumec Add transaction Producec Add Command Insert New Node Save Node Insert from File Rename Description Copy a node to the clipboard Delete a node Launch the node monitor (see “Node Monitor” on page 54) On regular nodes, this adds a Query and a Response. The two transactions will be grouped in order to increase readability. On the Broadcaster, a single transaction will be added.
Transactions 30 6.3 Transaction Parameters (Master Mode) 6.3.1 Parameters (Query & Broadcast) Parameter Minimum time between broadcasts (10 ms) Description This parameter specifies how long the gateway shall wait after transmitting a broadcast transaction before processing the next entry in the scanlist. The value should be set high enough to allow the slave devices time to finish the handling of the broadcast. The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.
Transactions 31 Parameter Update mode Description This parameter is used to specify when the transaction shall be sent to the slave: • Cyclically The transaction is issued cyclically at the interval specified in the “Update time” parameter. • On data change The data area is polled for changes at the time interval defined by Update time. A transaction is issued when a change in data is detected. • Single shot The Query is issued once at start up.
Transactions 32 6.4 Transaction Parameters (Generic Data Mode) 6.4.1 Produce Transactions Parameter Offline options for fieldbus Description This parameter specifies the action to take for this transaction if the higher level network goes offline. This affects the data that is sent to the sub-network.
Transactions 33 Parameter Trigger byte address Description This parameter specifies location of the trigger byte in the internal memory buffer. If “Update mode” is set to “Change of state on trigger”, the memory location specified by this parameter is monitored by the gateway. Whenever the trigger byte is updated, the gateway will produce the transaction on the sub-network.
Transactions 34 6.5 Transaction Editor The Transaction Editor can be used to edit the individual frame objects of a transaction. The same settings are also available in the parameter section of the main window, however the Transaction Editor presents the frame objects in a more visual manner. Frame Objects To edit the value of a parameter, click on it and enter a new value using the keyboard.
Chapter 7 7. Frame Objects 7.1 General Each transaction consists of Frame Objects which makes up the serial telegram frame. Each Frame Object specifies how the gateway shall interpret or generate a particular part of the telegram.
Frame Objects 36 7.3 Constant Objects (Byte, Word, Dword) Constant Objects have a fixed value and come in three sizes: • Byte 8 bits • Word 16 bits • Dword 32 bits Constants are handled differently depending on the direction of the transaction: • Produce/Query Transactions The gateway will send the value as it is without processing it. • Consume/Response Transactions The gateway will check if the received byte/word/dword matches the specified value. If not, the message will be discarded.
Frame Objects 37 7.4 Limit Objects (Byte, Word, Dword) Limit Objects have a fixed range and come in three sizes: • Byte 8 bits • Word 16 bits • Dword 32 bits Limit Objects are handled differently depending on the direction of the transaction: • Produce/Query Transactions This object shall not be used for such transactions (value will be undefined). • Consume/Response Transactions The gateway will check if the received byte/word/dword fits inside the specified boundaries.
Frame Objects 38 7.5 Data Object Data Objects are used to represent raw data as follows: • Produce/Query Transactions The specified data block is forwarded from the higher level network to the sub-network. • Consume/Response Transactions The specified data block is forwarded from the sub-network to the higher level network.
Frame Objects 39 To specify the properties of the object, select it in the Navigation Section enter the desired settings in the Parameter section as follows: Parameter Byte Swapping Description • No Swapping No swapping will be performed on the data • Swap 2 bytes A, B, C, D becomes B, A, D, C • Swap 4 bytes A, B, C, D becomes D, C, B, A Fill unused bytes • Enableda Fill unused data with the value specified in “Filler byte”.
Frame Objects 40 7.7 Checksum Object Most serial protocols features some way of verifying that the data has not been corrupted during transfer. The Checksum Object calculates and includes a checksum in a transaction. Parameter Error Check Start byte Error Check Type Description Specifies the byte offset in the transaction to start checksum calculations on.
Chapter 8 8. Commands This information is only valid for the Master and Generic Data modes. For DF1 master mode, please refer to “Services” on page 49. 8.1 General As mentioned previously, commands are actually predefined transactions that can be stored and reused. Just like regular transactions, commands consist of frame objects and are representations of the actual serial telegrams exchanged on the serial sub-network.
Commands 42 8.2.1 Drop-down Menu File This menu features the following entries: • Select Add the currently selected Command to the node. • Exit Exit without adding a command to the node. Command This menu is used to manage the commands in the list: • Add Command Add a custom command to the list, and open the new command in the Command Editor. See also “The Command Editor” on page 43. • Edit Command Edit the currently selected command using the Command Editor.
Commands 43 8.3 The Command Editor 8.3.1 General The Command Editor is used to define new commands and edit existing ones. This makes it possible to build a library of commands, which can be stored and reused at a later stage. Note that the Command Editor is somewhat protocol-dependent in the sense that certain frame objects may not be deleted or altered. The examples in this section use Master Mode.
Commands 44 8.3.3 Drop-down Menu File This menu features the following entries: • Apply Changes Save changes and exit to the main window. • Exit Exit without saving. Column The functions in this menu alters the structure of the command. • Append Column Add another column to the command. • Insert Column Insert a column at the selected position. • Delete Column Delete the column at the selected position. 8.3.
Commands 45 8.3.5 Example: Specifying a Modbus-RTU Command in Master Mode In the following example, a Modbus-RTU command is created in Master Mode. In Modbus-RTU, a transaction always feature the following parts: • Slave Address (1 byte) • Function Code (1 bytes) • A data field • CRC (CRC-16) Furthermore, each command always consists of a query and a response.
Chapter 9 9. DF1 Protocol Mode This mode makes the Anybus Communicator act as a DF1 protocol master on the sub-network. 9.1 General In DF1 master mode, communication is based on “services”. A “service” represents a set of commands and operations on the sub-network, that is predefined in the Anybus Communicator. Each service is associated with a set of parameters controlling how and when to use it on the sub-network.
DF1 Protocol Mode 47 9.2 Communicator Parameters Interface Currently, only serial communication is supported. Control/Status Word (See “Control and Status Registers” on page 62). Value Enabled Enabled but no startup lock Disabled Description Enable the Control and Status Registers. The “Data Valid”-bit in the Control Register must be set to start the sub-network communication.
DF1 Protocol Mode 48 9.3 Sub-network Parameters Communication These parameters specify the actual communication settings used for the sub-network. Parameter Bitrate (bits/s) Description Selects the bit rate Data bits Parity Physical standard Stop bits Selects the number of data bits Selects the parity mode Selects the physical interface type Number of stop bits.
DF1 Protocol Mode 49 9.4 Node Parameters To gain access to the parameters described in this section, select a node in the navigation section. For more information about nodes, see “Nodes” on page 27. Parameter Checksum Description Selects the type of checksum on the network. Slave Address Type The value entered here sets the node address. The PLC type of the slave Valid Settings BCC CRC (default) 0-254 PLC-5 SLC500 MicroLogix 9.5 Services Services are commands that can be stored and reused.
DF1 Protocol Mode 50 9.5.1 Available Services Right click on the node, and choose Add Command. A pop-up window will show the four different services that are available: • Integrity check • Read diagnostics • Read data • Write data A maximum of 50 services in total (for all nodes) can be selected. The predefined services can be configured to suit the application. Select a service to show the parameters.
DF1 Protocol Mode 51 9.6 Integrity Check This service checks that a node is up and running correctly. A telegram is sent to the node. The node mirrors and returns the telegram. No configuration is needed, apart from the general parameters, common to all services. 9.7 Read Diagnostics This service reads diagnostic information from the module. Command parameters The command parameter Size decides the amount of data that can be read.
DF1 Protocol Mode 52 9.8 Read Data This service is used to read data from the nodes in the sub-network. Command Parameters Parameter Description Element Number The element number of the data file to be accessed within the slave. File number File type Size Valid settings PLC-5: 0–999 SLC500: 0–255 MicroLogix: 0–255 The file number of the data file to be accessed. PLC-5: 3, 7, 8, 10–999 SLC500: 3, 7, 8, 10–255 MicroLogix: 3, 7, 8, 10–255 The file type of the data to be accessed.
Chapter 10 10. Sub-network Monitor 10.1 General The sub-network Monitor is intended to simplify configuration and troubleshooting of the sub-network. Its main function is to display the data allocated for sub-network communication and detect if any area has been allocated twice (i.e if a collision has occurred). All configured nodes, and their transactions, are listed in the middle of the screen (B). Selecting and deselecting single transactions makes it possible to view any combination of allocated data.
Chapter 11 11. Node Monitor 11.1 General The Node Monitor can provide valuable information when setting up the communication with the subnetwork, by allowing individual commands to be issued manually, and monitoring the response (if applicable). It also provides an overview of the memory used by a particular node. Note: The node monitor has a negative influence on the overall performance of the gateway, i.e. it should be used only when necessary.
Node Monitor 55 11.2 Navigating the Node Monitor A B C D A: Drop-down Menu & Toolbar Icons See “Drop-down Menu” on page 56 and “Toolbar Icons” on page 57. B: Command Section This section holds the currently selected command. The individual frame objects in the command can be edited in a similar way as in the Transaction and Command Editors. C: Response Section (Master Mode and DF1 Master Mode only) This section holds the response to the selected Command.
Node Monitor 56 11.2.1 Drop-down Menu File There is only one entry in this menu: • Exit This will close the Node Monitor. Note however that if the node has been disabled using “Stop Node” (see below), it will not resume data exchange until enabled again using “Start node”. Node This menu controls the data exchange for the node. This feature can help isolate problems associated with a particular node. • Start Node Enable the transactions associated with the node.
Node Monitor 57 11.2.2 Toolbar Icons The toolbar features icons for the most commonly used functions. • Start Node & Stop Node These icons corresponds to the functions in the “Node” menu. See also “Node” on page 56. • Start Stop Select Send Stop Resume Select Command & Send Command These icons corresponds to the functions in the “Command” menu. See also “Command” on page 56.
Chapter 12 12. Data Logger 12.1 General This feature allows the sub-network traffic to be logged into a buffer for examination. This may provide valuable information when debugging the lowest levels of the sub-network communication. Note that the logger function is part of the gateway itself and is separate from ACM. This means that logging can be performed even if the gateway is physically disconnected from the PC running ACM. 12.
Data Logger 59 12.3 Configuration By default, the log-buffer can hold 512 bytes of data in each direction. To specify a different size for the buffer, select “Options” in the “Tools”-menu. A window with various settings will appear. Select the “Module” tab, and enter the desired number of buffer entries under “Size of logbuffer” (valid settings range from 1–512). Click “Apply” to validate the new settings. Click “OK” to exit. Anybus Communicator PROFIBUS User Manual Doc: HMSI-27-306, Rev. 3.
Chapter 13 13. Configuration Wizards 13.1 General When creating a new subnetwork configuration, the Anybus Configuration Manager provides a choice between starting out with a blank configuration, or using a predefined template, a.k.a a wizard. The wizard automatically creates a subnetwork configuration based on information supplied by the user, i.e the user simply has to “fill in the blanks”.
Configuration Wizards 61 13.3 Wizard - Modbus RTU Master This wizard can be used to create a Modbus-RTU-based network configuration based on certain information about the subnetwork. The online help system explains each configuration step in detail. • Important Notes: Many OEM devices do not fully comply with the Modbus standard. For example, they may implement a variation of this standard or be limited to the use of specific Modbus commands other than the ones used by this wizard.
Chapter 14 14. Control and Status Registers 14.1 General The Control and Status Registers are disabled by default, but can be enabled using ACM (see “Control/ Status Word” on page 25). These registers form an interface for exchanging status information between the sub-network and the fieldbus control system. The main purpose of these registers is to...
Control and Status Registers 63 14.1.2 Data Consistency The “Data Valid”-bits in the Control and Status Registers are used to ensure data consistency during start-up and fieldbus offline/online transitions. If the “Control/Status Word”-parameter in ACM is set to “Enabled”, the gateway will wait for the fieldbus control system to set the “Data Valid”-bit in the Control Register before it starts exchanging data on the sub-network.
Control and Status Registers 64 14.2 Status Register Contents (Gateway to Control System) 14.2.1 General Information The Status Register is (if enabled) located at 0x000–0x001 and constitutes a bit-field as follows: bit(s) 15 14 13 Name Send (SR_HS_SEND) Confirm (SR_HS_CONFIRM) Data Valid (Master Mode and DF1 Master Mode Only) 12... 8 Status Code 7... 0 Data Description These bits control the handshaking towards the fieldbus control system.

Chapter 15 15. Advanced Fieldbus Configuration 15.1 General The fieldbus interface of the gateway consists of an embedded Anybus-S communication interface. Normally, the Anybus-S configuration settings are set up automatically by the gateway. However, advanced users can configure the Anybus-S card for specific features. This chapter assumes that the reader is familiar with the Anybus-S and it’s application interface.
