2 connections to same PLC, different target port #13

Hi,

I want to make 2 connections to the same plc. first connection to target port 851, second connection to target port 852. (twincat 3). I tried it but with no succes. the moment the first connection is established, the 2nd connections is rejected. In my config, host, targetnetid, sourcenetid and port are identical, only Target Port is different. Is this behaviour as expected or should it be possible to have 2 connections? If so, how?

kind regards Pascal

I think that it is the same problem as with the Systemmanager and an ADS client. The ADS router on the PLC will not be able to route the correct port to the correct IP.
