Program Checksum

[tstevic 0]

Many years ago, if someone would take a memory module out of an Omron plc and put it in a new processor, the plc would generate a memory error. The way this was fixed was to place the plc in program mode and read the first entry of the program memory, then enter was pressed on the programming console. Error fixed. We were told that this would cause the processor to generate a new program checksum based upon the program code stored in the memory module. I am wondering if this program checksum is still generated and if there is a Fins command to read it? T
