I just created a ml1200 file.
you cannot write to this address, it is a status bit.

you can write to this bit in the ml1000.

different processors has different restrictions and the bits may be different.

You mean S:1/8 Fault Override at Power-Up bit, it's also available in Micrologix 1200

see this technote from Rockwell
