I read some weeks ago, that from a certain FW-version even PAC3200 can hold two Modbus connections. But I couldn't find the related FAQ or tread.... Please note, you can't use port 502 several times. But the port number is defined and mentioned somewhere in the PAC manual. Regards, Kaulquappe Finally I found the tread: https://support.industry.siemens.com/tf/ww/en/posts/96227/
