Hi guys.

I have this FX2N, programed using GX Developer 2.

Some strange phenomenon has occurred.

this command [DMCP D252 D430 M80] has caused my FX2N to NOT output any digital value, like when im trying to force Y00 to 1 but not turningit on in the PLC. When i force the value of D430 (originally some value like 99999999) to 0 (cero) then the forced Y0 has an output.

It is as if this command (or even more, the register D430) causes a conflict inside the PLC. I tried to use another register like D360 thinking maybe this specific register has problems, but nothing happened.

some context: The original program inside the FX2N has been deleted due to the battery dropping its value to 0,8V. I got the "original" program from the Chinese, and when i tried to find out why the FX2N did not have any output during testing, i encountered this issue with D430.
the original value of D430
+0 +1 +2 +3 .... +9
D430 -7937 1525 0 0 ... 0

what nr error on fx2n device do you get?
The program is developed on Chinese GXDev and you are using GXDev in English?
Did you execute a Factory reset before loading the backup program?
