I’m having a very annoying problem with I/O units not connecting in the strategy, even when I try to enable the connection manually it doesn’t even holds the set timeout, it is just too quick and doesn’t connect. IP addresses are correct, I can ping them and even connect to the units with PAC Manager and no problems. I tried with the strategy downloaded to a physical SB1 and with PAC Sim and the behavior is the same. Has someone experienced something similar? Everything was working perfectly and suddenly this happened.
