Processor is a L32E
For some reason, I thought that there was a tag member that would give a status on Ethernet communications for a powerflex 525 VFD. But I cant find it anymore.
Currently program that i'm looking at is writing a negative value to the tag "I.OutputFreq" and then waiting for that value to be corrected by the VFD.
That system works for detecting com loss, but we've always had intermittent troubles with VFD's not starting when commanded (for no apparent reason) or not reaching the proper speed, faulting, or showing comm loss, and i'm wondering if writing to that tag (I.OutputFreq) could be the cause.
How do you guys detect when Ethernet communications to a PF525 are lost?
