We finally got off the dock last night just after midnight and already the fun has started.
The 1756-L81ES processor in our fishmeal plant had no program in the controller when I got on shift.
Reading over the Rockwell literature I see no mention of this processor having a battery. Am I correct in that assumption?
The processor is connected to a UPS though.
No one else onboard with access to the software has touched the controller in the past 24 hours, so I can safely rule out someone writing over the program with a blank file. (unless it was done remotely by the contractor that installed it, which I highly doubt)
Reading though knowledge base search results and archived post here on this forum I do see others saying they have had similar issues, although not with this exact controller model number.
Anyone else experience anything similar, and if so were you able to find the cause?
