Hello ,

I have 2 weighing indicator(CI-5200A) that supports modbus rs232 ASCII. In the plc(S7-1200) side I have CM 1241 (RS422/485) module and between plc and indicator I have RS485 TO RS232 converter.

My question is how can I communicate one master RS485 to indicator slave rs232 through RS485 TO RS232 converter. 

I tried to do it via block RCV_PTP . But with this block I can make only one master and one slave.

Closed because posted twice. The active topic can be found here:
