Modbus master-slave driver

The driver addon “Modbus Master/Slave” enables communication with Modbus RTU-compatible devices. With this driver, the SAS 341 can operate either as a Modbus RTU master or Modbus RTU slave.

Modbus Master/ Slave Driver, for SAS 341-1

The driver is used for the SAS 341-1 with RS232 interface (700-341-1AH02) or for the SAS 341-1 with RS485 interface (700-341-1CH02).
With the RS232 interface, a point-to-point operation is possible, and with the RS485 interface, up to 32 participants can be addressed using the 2-wire half-duplex method.
In the communication with other systems, the Modbus RTU function codes 01, 02, 03, 04, 05, 06, 07, 08, 11, 12, 15, and 16 are supported.
The data exchange with the S7-CPU is in blocks in the supplied function blocks.
