Hi! I was searching for an RS-485 module for Modbus communication, but could not find any. Looks like such an S7-200 module does not exist. However, I have found these posts and read the System manual: https://support.industry.siemens.com/tf/ww/en/posts/modbus-on-both-ports/50057/?page=0&pageSize=10 So it looks like that what I want might be possible. The only drawback is that I will use up both CPU ports for Modbus and if I have to connect to the PLC with MicroWin, I have to put it in Stop mode (in order to change the operation of the ports back to PPI) |
