Review the PLC program so that data is not written
continuously to the flash ROM. (Using "
Md.19 " in
Section 5.6.1, the number of flash ROM write times can
be monitored.)
(If this error has occurred in a proper using method,
writing is enabled by resetting the error, switching
power OFF, then ON, or resetting the PLC CPU.)
