Problem in transferring input values from Redundant PM591_ETH CPUs to builder plus
We have a redundant project using 2 PM591-ETH CPUs, 3 racks of remote I/Os (consists of AI531s & AX521s) using 3 CI590s. We have used the onboard ETH on PM591_ETHs for both programming the CPUs and syncing them by using scalance switch. The project has no error and we can login PLCs correctly. Sometimes after login to PLCs, a problem is occured which is the input values are not transferred to builder plus or transferred incorrectly; for example, some inputs in AI531 are represented as inputs in AX521.
Do you have any opinion why this problem happens? Can it be results of using same ethernet port for both programming and syncing?
