Chapter 15 Dedicated Instructions
(3) After the power ON and PLC CPU reset operation, writing to the flash ROM using
a sequence program is limited to up to 25 times. (Not limited to up to 25 times
when writing to the flash ROM is carried out by GX Works2.)
If the 26th or more writing is requested after the power ON/PLC CPU reset
operation, the error "Flash ROM write number error" (error code: 805) will occur,
and the writing will be disabled. If a flash ROM write error occurs by one writing to
the flash ROM, check and correct the flash ROM writing program. Then reset the
error or turn ON the power and reset the PLC CPU again.
[Program example]
The following program initializes the parameters in buffer memory and flash ROM
when X3C turns ON in LD77MS4.
