You cannot create a Quantum Hot Standby configuration running one 140CPU53414A PLC with Unity firmware and one with NxT firmware. 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.
140CPU43412A Error Codes
The following are the error codes for the 140CPU43412A:
Any loss of communication during the update procedure can cause severe damage to the CPU or NOE module. Failure to follow these instructions can result in injury or equipment damage.
Reset the PLC
Once the download of the intermediate binary file has completed, the PLC has to be initialized. This task can be performed by one of the two following actions: Reset the PLC by pushing on the Restart button located on the CPU (for more information, refer to the PLC technical documentation). Power OFF then ON the PLC. Once the PLC has restarted, go to Phase 3: download the final Concept OS.
Phase 3
Presentation
The final binary file “q5rv135E.bin ” (140CPU34312 in our example) has to be downloaded. For that, follow the same procedure as the one described in the Phase 1.
Checking Version (optional)
If needed, you can check the new CPU version. For that Open the OS loader tool. Select the communication protocol. Click on “Connect.” Then Click on “Properties.”

Phase 1 – Restore the PLC to Concept with an intermediate OS.
Phase 2 – Power OFF then ON the PLC.
Phase 3 – Restore the Operating System with the appropriate file.
These phases are mandatory and cannot be by-passed.
Phase 1:
Launching the OS Loader
The OS loader (provided with Unity) allows the user to download the Operating System to the PLC. To open it click on Start/Program/SchneiderElectric/Unity-PRO/OS loader.
Select the Communication Protocol
From the main screen of the OS loader, click on the “Next” button. To download the Operating System into the PLC, select the right communication protocol (in accordance with established physical link) and click on the “Next” button.
Select the Target Device
On the Device Type field, select Processor and the other needed parameters (Modbus address….). Then connect to the selected PLC (Node).
Select the Download Function
From the screen described above press the “Next” button. A new screen is proposed: select “Download OS to device”.
Select the File to be Downloaded
Click on the “Browse…” button in order to select the file to download into the PLC. In this example we will restore the OS from 140CPU43412U to 140CPU43412A firmware. For that select the following folders: Quantum\Processor_modules\Unity_to_Concept. To restore the OS from Unity to Concept, two binary files can be selected: Unity_to_Concept_43412A.bin (allows to “format” the processor to Concept) q5rv135E.bin is the OS that will finally be downloaded in the processor. In our example we have to “format” the processor (remember, we still are in the Phase 1) then select and Validate “Unity_to_Concept_43412A.bin”. Once done click on the “Next” button.
Download the Intermediate OS
Once the previous screen is validated a warning is displayed: Click the “Okay” button. Two screens that give information regarding the file, the processor and the download are now displayed. Note: If the system detects a discrepancy on the hardware or on the OS version, the download will not be possible. This is indicated by a red cross and the “Next” button becomes unavailable. Solve this issue and continue. When the hardware – OS are compatible, click on the “Download” button to launch the download of the intermediate OS file.

Front Panel Topology
There are two switches (a three-position slide switch and a three-position key switch) located on the front of the 140CPU43412A configuration. The module has a single slide switch that is used to select the comm parameter settings for the Modbus (RS-232) ports.
Rear Panel Topology
The address switch, which is comprised of two rotary switches, is located on the rear panel of the Quantum CPUs. The address switch is used for setting Modbus Plus node and Modbus port addresses. SW1 (the top switch) sets the upper digit (tens) of the address, SW2 (the bottom switch) sets the lower digit (ones) of the address. The illustration below shows the correct setting for an example address of 11.
Option Module Interface Support
The 140CPU43412A firmware supports up to six network modules (i.e., Modbus Plus, Ethernet, and Multi-Axis Motion option modules) using the option module interface technique. However, only two Modbus Plus modules can have full functionality, including Quantum DIO support.
During the 140CPU53414B firmware configuration, there are two switches (a three-position slide switch and a three-position key switch) and one connector (Modbus RS-232) located on the front of the CPU.
The slide switch is used to select the comm parameter settings for the 140CPU53414B configuration of Modbus (RS-232) ports. Three options are available, ASCII, RTU, and mem.
The Modicon Quantum 140CPU53414B is a Schneider Electric CPU module which is supported by Concept and ProWORX software. The CPU can also be used with Unity by upgrading the exec file. This CPU is currently at the forefront of the Quantum series and one of the more popular CPUs for many PLC systems.
On the front of the 140CPU53414B there are two switches, a three-position slide switch and a three-position key switch. The slide switch is used to select the comm parameter settings for the Modbus RS-232 ports. Setting the slide switch to the top position assigns ASCII functionality to the port.
We will be continuing a series with more info on the 140CPU53414B along with troubleshooting info the the CPU, as anyone who has had their CPU go down knows the price of their line being out of commission. For more technical data you can check out the PDFs on our site that include the manual for the Quantum series.
The Quantum 140CPU43412A CPU is a single-slot programmable controller with built-in executive memory, application memory and communication ports. All memory components are on board so no additional chips or cartridges are necessary.
Quantum CPUs use flash memory technology to support the CPU’s executive memory and instruction set. Flash is a state-of-the-art, nonvolatile memory technology that enables downloadable field upgrades as new features become available.
The application program can be stored in either battery-backed RAM and/or Flash RAM. The battery is located on the front of the CPU and can be serviced while the CPU is running. To protect the application program from inadvertent changes during operation, the 140CPU43412A features a memory-protect switch. An LED goes on when this switch is activated.
The 140CPU43412A CPU has two Modbus® ports and one Modbus Plus™ port. Simple rotary switches on the back of the CPU are used to set the network address of the Modbus Plus port. Each device on a Modbus Plus network must have a unique address in the range 1 … 64.
As an option, modules can be ordered with a conformal coating applied to protect the internal circuitry from corrosive gases such as Chlorine,Nitric Oxide, Hydrogen Sulfide and Sulfur Dioxide.
The Schneider Electric Modicon 140CPU53414B CPU is one of the main CPUs of the Quantum Series. It is no long in production from Schneider, but we do still have new and refurbished units available. To make sure this is the CPU is the one for your system we have the notes and overview below.
Overview
– The 140CPU53414B is functionally identical to the non-B version, however the following must be considered:
– If you are using the CPU in a hot standby system, you must use either two non-A versions, two A versions, or two B versions. – The B version required a new flash exec.
– The B version, A version, and non-A flash execs are not interchangeable.
– Schneider software (Concept, ProWorx, and Modsoft) supports the B version.

We currently have both new and refurbished 140CPU43412A CPUs in stock, fully tested and ready to ship out same day if need be. This Modicon 140CPU43412A CPU is one of the more popular CPUs in the Quantum Series from Schneider Electric/Modicon.
Just as a side note, we often get questions as to what the differences between Schneider Electric, Modicon, Square D, and Telemecanique are. Modicon, Square D, and Telemecanique were all bought by Schneider Electric over the years and their products are all now manufactured by Schneider. A full history of the Schneider Electric acquisitions is available on Wikipedia here.
Back to the CPU, if you are looking for the general description or the technical specs, here is a link to the PDF listed on Graybar’s website. The predecessor to this CPU is the 140CPU43412, where the 140CPU43412A is functional identicial to the non-“A” version, the only differences being that if you are using multiple units in a hot standby system you need to use either two 140CPU43412 units or two 140CPU43412A units, and the “A” version has a unique flash executive which isn’t interchangeable. We have another blog post detailing the differences here.
Below we have a video of the product itself to help with anyone who is looking for replacement. For pricing or any other questions give us a call a 800-691-8511 or email sales@mroelectric.com.
One of the more common Modicon Quantum CPU modules is the 140CPU43412A CPU module. This unit replaced the 140CPU43412 unit which has since become obsolete. Currently, many systems are being updated so we consistently get questions about 140CPU43412A CPU replacement and what the differences between the two units are, and if they are plug-and-play replacements. To help with this transition, we put together a few notes to help anyone who has questions.
The redesigned unit designated with the “A” at the end is functionally identical to the original non-“A” unit, with a few slight considerations. If you are using this CPU in a hot standby system, you must use matching units, so either two 140CPU43412 units or two 140CPU43412A units. Additionally, the 140CPU43412A version has a unique flash executive, and the two unit’s flash executives are not interchangeable. For the software, all the standard systems (Concept, ProWORX, and Modsoft) support the 140CPU43412A unit, and any 140CPU43412 program will load directly on to the new 140CPU43412A without needing to be changed.
