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.
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.”
For ordering info or for a 140CPU43412A price quote you can call 1-800-691-8511 or email email@example.com.
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.
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.
