Corso Systems needed to map a value coming from an Automation Direct PLC via Modbus TCP into a scaled integer value in an Ignition SCADA system. Automation Direct uses a non-standard format for their data compared to most Modbus TCP implementations. To accomplish this we used a bitmask, a tag change script, and a UDT in Ignition to get the job done.
