14. RS485 interface - Protocols

The TR 1200 optionally supports the Modbus or the ZIEHL RS485 protocol.
Device data and measurements can be read out with both protocols; in addition,
the TR 1200 can be configured using the Modbus protocol.

The protocol is selected in the menu item

bus.

(see

8.9 Configuring RS485 interface

)

14.1 Modbus protocol

You can find documentation on the Modbus protocol in the Internet at
