Cannot read some tags inside Rockwell AOI

Hey Phil, I'm a bit embarrassed to ask, but how in Perspective do you recommend issuing commands from SCADA to xyz_cmd registers, and having them reset themselves from SCADA (without PLC writing to them) so as to avoid race conditions? This still confuses me.. would you suggest tag value change scripts to do this resetting?
