The 2 different Wizcon 7.61 systems are connected with a switch (100 Mb) to two Schneider Quantum PLC's by a 140 NOE 771-01 communication card.
Both PLC's control a different proces part. When we use the both SCADA system on proces part 1 there are no problems. But when both SCADA systems are used for proces part 2 there are problems. The values sometimes are not reliable (there are zero's).
