What are the points to note when using a program that has been used for FP0 to FPΣ?

I replaced FP0 (10K) with FPΣ to increase the number of I/O points. I changed instruction F144 to F159 for general-purpose communications with RS232C equipment. However, unnecessary communication is performed when the power is turned on after the power is kept off for a period. In addition, an internal relay that is not set to the hold type is sometimes turned on without being instructed.

ANSWER
Install memory backup battery AFPG804 .
The optional battery should be purchased for FPΣ, while FP0 (10K) has a built-in secondary battery. The data in the hold area becomes undefined unless it is backed up.
