0020h: User Program RAM Sum Check Error
The data of the user program compile area in the
user program is recompiled automatically, and the timer/counter preset values and expansion data register preset values are
initialized to the values of the user program. Note that changed preset values are cleared and that the original values are
restored. Clear the error code using the HMI module or
0040h: Keep Data Error
This error indicates that the data designated to be maintained during power failure is broken because of memory backup
failure. Note that the "keep" data of internal relays and shift registers are cleared. Data of counters and data registers are
also cleared. Clear the error code using the HMI module or
If this error occurs in a short period of power interruption after the battery has been charged as specified, the battery is
defective and the CPU module has to be replaced.
0080h: User Program Syntax Error
This error indicates that the user program has a syntax error. Correct the user program, and download the corrected user
program to the MicroSmart
