Page 10: About The Anybus Communicator Modbus Plus
Chapter 1 1. About the Anybus Communicator Modbus Plus The Anybus Communicator for Modbus Plus acts as a gateway between virtually any serial application protocol and a Modbus Plus-based network. Integration of industrial devices is enabled without loss of functionality, control and reliability, both when retro-fitting to existing equipment as well as when set- ting up new installations. -

Page 16: Basic Operation
2. Basic Operation 2.1 General The Anybus Communicator is designed to exchange data between a serial subnetwork and a higher level network. Unlike most other gateway devices of similar kind, it does not have a fixed protocol for the subnetwork, and can be configured to handle almost any form of serial communication. -
Page 17: Data Exchange Model
The gateway can handle up to 1024 bytes of General Data. 2.2.1 Memory Map When building the subnetwork configuration using the Anybus Configuration Manager, the different ar- eas described above are mapped to the memory locations (addresses) specified below. Input Data... -

Page 20: Master Mode
In Master Mode, Anybus Configuration Manager comes preloaded with most commonly used Modbus RTU commands, which can conveniently be reached by right-clicking on a node in the Anybus Config- uration Manager and selecting ‘Insert New Command’. Note however that this does not in any way pre- vent other protocols based on the same query-response message-scheme to be implemented. -

Page 33: Chapter 5 Nodes
5. Nodes 5.1 General In Anybus Configuration Manager, a node represents a single device on the network. While the gateway doesn’t feature a scanlist in the traditional sense, all nodes, and their transactions, will be processed in the order they have been defined in the Anybus Configuration Manager. -
Page 34: Chapter 6 Transactions
As mentioned previously, transactions are representations of the actual serial telegrams exchanged on the serial subnetwork. While the gateway doesn’t feature a scanlist in the traditional sense, all nodes, and their transactions, will be processed in the order they have been defined in the Anybus Configuration Manager. -

Page 53: Df1 Protocol Mode
Chapter 9 9. DF1 Protocol Mode This mode makes it possible to let 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 subnetwork, that is predefined in the Anybus Communicator. -
Page 54: Abc Parameters
Value Description This mode is intended for the DF1 protocol. The Anybus Communicator can only be con- figured as a Master with half-duplex communication. Note: This is the only mode available if you intend to configure an ABC module for DF1. -
Page 55: Subnetwork Parameters
The default value is given as 100 in the parameter window. Each change of 10 ms either increases or decreases this value by 1, i.e. 99 represents a poll time of 990 ms and 101 represents a poll time of 1010 ms. Anybus Communicator for Modbus Plus Doc.Id. SCM-1200-093... -
Page 56: Node Parameters
A total of 50 services are allowed. The Anybus Communicator supports a selection of DF1 commands. When the gateway is going to ex- ecute a service, it automatically chooses the appropriate DF1 command(s) that are used to perform the service on the selected DF1 node type. -

Page 69: Control And Status Registers
14. Control and Status Registers 14.1 General The Control and Status Registers are disabled by default, but can be enabled using the Anybus Config- uration Manager (see “Status / Control Word” on page 28). These registers form an interface for ex- changing status information between the subnetwork and the fieldbus control system. -
Page 70: Data Consistency
If the ‘Status / Control Word’-parameter in Anybus Configuration Manager is set to ‘Enabled’, the gate- way will wait for the fieldbus control system to set the ‘Data Valid’-bit in the Control Register before it starts exchanging data on the subnetwork. -
