Yes, M238 Modicon controllers have the capability to store the SoMachine source code.
- To download the source code to the M238, the M238 will have to be in Stop mode. After that go to the Logic Builder menu / File / Source download.
- To upload the source code from the M238, the M238 will also need to be in Stop mode. If the PLC is Run mode, the message "No source archive available on the plc" will be displayed when the upload is performed from either Logic Builder menu / FIle / Source download (when offline) or from SoMachine Central / Connect controller.
Important note: The M238 does not have a Start/Stop switch and the only way to stop the PLC is to connect to the PLC with any project. That presents the risk, that if no source code is on the PLC, the existing program that is stored in flash (the compiled code, loaded to RAM on power-up) will be overwritten. If the source code is available, that can be used to generate the compiled code to download to the PLC.
M238 is an obsolete product.
