I currently am working on Mitsui Seiki with Fanuc 150 M control. I use G10 statement to change i/o channel for DPRNT out serial port, been doing this for years. the following exicutes without alarm but parameter 21 is not changed.
G10L50
N21R2
G11
I can change manually but I need to change it via macro statement above. it even states in the Fanuc manual this parameter can be changed via G10L50.
G10L52 will give invalid G command alarm. Im thinking Keep relay or something.
I've been working with Fanuc and other controls for many years but I haven't seen this one yet. if anyone has advice please do post.
Thanks
MJC
