Is the ProSoft PTQ-PDPMV1 a direct replacement for Modicon part number 140 CRP 811 00?

While the PTQ-PDPMV1 is very similar in capability and performance to the older Modicon 140 CRP 811 00 module, it is not a direct, drop-in replacement.

If you wish to replace a CRP with the PTQ, there will be some project modifications required to get it all working.  The type and extent of modifications will depend on the complexity of your existing Quantum application.
