Hi all,
Hopefully somebody has a quick and easy answer to this one. I had to make some program modicfications to an existing program in a DL405 (450CPU). I made the changes, all went well and I wrote the program to the PLC to update the changes. However, now I do not seem to be getting any output from all three of the PID loops. I checked them, and all programming in terms of V locations, etc is still there. Did I stop the loops somehow when I made the proramming changes? I checked the output V memory locations in a data view table and they are zero for all 3 loop outputs??? Also, the Process Variables are loaded into the appropriate V-memory locationsas well. Is this a Directlogic glitch?? Thanks in advance for any help.
Sincerely,
SG
