SLC BTR/BTW Problem

[jpocreva]

Hi ,

I have an SLC 505 that I made some changes to. After the changes were made the BTR and BTW instructions became extremely slow. I did not intentionally change any of this ladder logic for this I/O. It takes about ten seconds for the I/O to update / scan. Can anybody point me to what might be causing this issue?

Thanks in advance.

What changes did you make? Can you post the before and after .RSS files?
Zip them first then post.
