A customer of ours had a power outage for more than what his On-Line UPS could handle--so the system went down for some time (about 1/2 hour) When it came back up---everything was fine except that EX 107 --the last port on the first card is now Ex 134---a station port that wasn't programmed nor even had a supportive card We checked Flash 51 (I think) and saw that the system now sees that the location where 107 should be---is now 134 and vice-versa. What is the easiest way I can get Ex 107 back to where it's supposed to be. We tried a power-down and changed to a different card---but to no avail. It seems like there is corrupted data. Any ideas?? Thanks in advance. Maybe my manual is missing some pages---but I don't see any port/extension programming nor a reset that can fix any corrupted data. I seem to have seen that years ago, but not now.
