Frequently Asked Questions Related to the Schneider Electric / Modicon 140CPU43412A

 

Will the latest firmware (v1.44E) for the 140CPU43412A work for a PLC programmed with ProWORX NxT?
Yes. The q5rv144e.bin file supports both Concept (IEC & 984) and ProWORX PLCs.

Is it possible to upgrade a 140CPU43412 [non A] from Concept to Unity Pro?
No. Only the 140CPU43412A with a PV:04 or greater can be upgraded to support Unity Pro. If the (A) version is PV16 or greater you need to use the RoHS firmware.

What would cause a “Memory Protect is ON. Download not possible” message when trying to download a Concept Project into a Quantum 140CPU43412A?
If the Key Switch on the 140CPU43412A is either in the “Mem Prt” or “Stop” position, the memory is protected from a programming change. Put the Key Switch in the “Start” position.

Can the Quantum 140CPU11303 be programmed in both IEC and 984LL using Concept?
NO. The 140CPU11303 can either be 984LL or IEC but not both. If you need to have both IEC and 984LL sections, will need to go up to the 140CPU43412A.

What is the replacement for 140CPU42402?
We’ll let you guess (hint: its the 140CPU43412A).

Can I create a Quantum Hot Standby configuration running one 140CPU53414A PLC with Unity firmware and one with NxT firmware?
No. When using an NxT configuration in hot standby, both PLCs must have NxT firmware. When using a Unity Quantum hot standby configuration, only specific hot standby controllers can be used. The 140CPU43412A and 140CPU53414A PLCs are not supported in Unity Hot Standby configurations.

What is the power dissipation for the 140CPU43412A module?
6.25W

Which Quantum PLCs allow the use of an Aux task in Unity?
The 140CPU65150, 140CPU65160, and 140CPU67160 allow the use of Aux tasks numbered 0 thru 3. The 140CPU31110, 140CPU43412A, and 140CPU53414A will only allow the use of a Fast and a Mast task.

Which Quantum controllers support Concept IEC Hot Standby?
The following Quantum controllers support Concept IEC HSBY:
140CPU43412
140CPU43412A
140CPU53414
140CPU53414A
140CPU53414B

Does the 140CPU43412A have the Factory Mutual (FM) Class 1 Div. 2 rating?
Yep.

Where on Eclipse can I find the firmware for the 140CPU43412A?
After logging into Eclipse, try the following navigation:
My downloads
Firmware
Select ”Modicon Quantum” from the pull down.
Sort by “Created” and “Descending” so that you see the most recent listed first.
Item 140CPUX341XA Flash Exec (English) contains the firmware files.

Can the Quantum 140CPU11303 be programmed in both IEC and 984LL using Concept?
No. The 140CPU11303 can either be 984LL or IEC but not both. If you need to have both IEC and 984LL sections, will need to go up to the 140CPU43412A.
