At our plant we have mostly AB PLCs, but in one area we have some Modicon PLCs. The AB should send info (i.e. weight, product code, etc.) to the Modicon. The DH+ connections are all good, but from time to time we will lose some of the info and that causes us problems in our product flow. Could it be that the data from the AB PLC is not understood by the Modicon PLC, or could there be some other reason? HELP!!!
