We have an APACS+ DCS. The system has worked fairly well, until we recently had a shutdown. When we restarted, a couple of our controllers (an ACM and a CCM) have very high scans. For the CCM: prog. execution=38, sys. & comm=39; for ACM: prog. execution=84, sys. & comm=12.
Were not sure why this happened, Siemens recommends no more than 60% total%scan and its starting to cause issues with some other systems. Any ideas?
