Title: BRX dropping out of run
Post by: jwbaker3 on July 07, 2026, 12:38:23 PM

I have a system with 4 Brx plc's and a AB 5069 networked together, the Brx will randomly drop out of run. Cycle the switch and all's good (except restarting the system) could this be due to firmware? Or ? any ideas? we are talking to 5 Fanuc robots and 21 drives and messaging information between the Brx, the AB had one of the Brx setup as remote IO
Thanks,
JW
