  If the size of the memory preservation file is invalid in Omron Controller, the values on the memory (e.g. UM) of the Ladder Engine are indefinite. Initialize the I/O memory area of the Ladder Engine by following these steps: 1. Exit the CX-Simulator. 2. Delete all Memory?.dat files in the PLC data folder where an error occurred. 3. Restart the CX-Simulator and specify the relevant folder to start the Ladder Engine.
