Hi everyone,
I have S7-400 PLC and needs to communicate with the "Quick Panel Control (GE)". This comunication is MODBUS-RTU 4-wire, I'll use a CP-341 as a master and a slave PLC GE. I do not know how to configure the CP-341 as Master. Could someone help me?
Thanks in advance.

Hi,
You need to install Loadable driver CP PtP Modbus Master (https://support.automation.siemens.com/ ... reeLang=en). Also You need Modbus master hardware dongle 6ES7870-1AA01-0YA0 which is plugged in rear part of CP341.
regards
