Can a PLC programmed with ProWORX NxT support a 140CPU43412A with the latest firmware?

  • Both the Concept (IEC & 984) and ProWORX PLCs are supported by the q5rv144e.bin file.

What is the replacement for the 140CPU43412A?

  • The replacement for the 140CPU43412A is the 140CPU43412U.

Why is the Quantum Unity PLC 140CPU43412A’s timer resetting on a power cycle?

  • The timer resets on a power cycle because the customer has made a Project Backup. When a Project backup is made, every power cycle will result in a cold restart (%S0). This cold restart will reset all timers.

Is it possible to upgrade a 140CPU43412 [non A] from Concept to Control Expert (formerly Unity Pro)?

  • No. Only the 140CPU43412A with a PV:04 or greater can be upgraded to support Control Expert (formerly Unity Pro.)
MRO Electric provides a 2-year warranty on every item we sell and repair. We stand behind all of our products and guarantee them for the full 2 years. If there is an issue with any of our products within the warranty period, we will evaluate the unit and repair or replace it under warranty.
