Hello, I have a A.B Compact logix communicating with two fanuc robots via ethernet. The plc also communicates to an automation direct hmi screen. For a while, the HMI began lagging a little bit on the cycle timers I had on the screen (meaning it would be counting up, then pause, then suddenly jump to the correct #). I swapped out the ethernet switch box for a new one from a different company, and it went back to working well for about 6 months, until the HMI began lagging again. I'm assuming it's a ethernet box issue since after swapping it out the first time, there was no lag for about 6 months. I plan to also add a PC which showcases the ladder logic live and also a remote io block, so I'm worried this will also slow down all the communication and definitely do not want any lag, especially between the robot and PLC.
Thanks,
Thanks,
