Hello.
I have some 900 parameters for the fanuc ot controler.
My 900 parameters are vissable,and when i set my pwe to write anable i can write in my parameters.
but when i want to write a specifit bit of a 900 parameter i can only writy the last 2 bits.
For example.
to change parameter 940 from 00000000 to 10000000.
this wil work.
but change from 00000000 to 00000001 it wont work.
In both change i gat the 100 and 101 alarm,so turn af the machine and turn it on again.
but even then it wont work. for the last option

I hope someone can help me.
