Has anyone experience with 2 raspberries running codesys?
We try to connect 2 Raspberry Pis using codesys on each of the two, selecting one as master and the other one as slave.
Unfortunately the TCP connection cannot be established ,
The master starts with SYNC, then the slave answers with ACK+RESET and so the master again tries with SNC .... eternally ...
We downloaded the codesys image, after installation: apt-get update, apt-get upgrade and finally installed wireshark apt-get install wireshark.
Thanks a lot in advance

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Attached the project.
Attention: This is done with 3.5SP5 this week is release, but if you want to use with 3.5SP4 - update the plc device (right lick on the device in the devicetree)
and go gack to 3.5.4.x version of the plc.
