What serial protocols does Anybus Communicator Classic support?
Master Mode: The Anybus Communicator Classic is a Master and the customer can connect 1-31 Slave nodes to one Communicator. The register mapping and set-up are done with the Configuration Software that runs on a PC. A Visual protocol description system for Modbus-RTU and DF1 Master makes it very easy to configure the serial sub-network. In addition the Communicator can also support custom Response/Request protocols. Contact HMS to learn more about custom protocol support.
Generic Mode: Generic mode is built on the produced-consume methodology and any type of telegram can be created for cyclic or change-of-state update. This can be used for simple serial devices, such as barcode readers and text displays that just send or receive a flow of serial characters, commonly called ASCII communications. The Communicator Classic supports the serial interfaces RS232, RS422 and RS485. This is selected by software in the Configuration Program.
DF1 Mode: This is a specific mode that is used only with the Rockwell DF1 communication protocol supported by some of the Rockwell PLCs.
