Question on Modbus Comms

    Hello,

    We have a client that will be using quite a few modbus devices. One thing he asked about, which I wasn't sure of an answer, is how does Mango handle modbus CRC and any partial data transmissions / failures?

    • Is this something that one of the Exception alarms would capture?
    • If we're using a slave monitor point, what value would that data point have? I'm guessing 0 since it's not a successful transmission, but not sure.

    Any information is appreciated.

    Thanks,
    Chad

    Hi @cmusselm

    These would generate a data source exception event if a poll for a specific Modbus slave fails for any reason the monitor will be set to 0.
