Our plant systems have been upgraded to newer Modicon PLCs and I was required to buy Unity XL 11.0 to work on these systems. We have Modicon VFDs connected to the Quantum 140 65150 CPU via Modbus plus. I have to change a drive Altivar 66 to Altivar 58. Have to change the drive address in PLC because 66 and 58 are different. HELP Please. Can't find any place in PLC where 66 addresses were used.
