Dear all-knowing list I have two FCP270's with an OM scan % load approximately 4% higher than the maximum recommended. They both have multiple independent sequence blocks direct addressing values in another processor. Would reducing the scan rate of the independent sequence blocks and offsetting the cycles help to lower the OM scan %? Also one has multiple values been read and written to from a Delta V system through OPC, wondering if that would increase the OM scan %? I haven't found a very clear definition of what affects this value or what you can do to lower it if needed other than getting another processor. Any help is greatly appreciated. -- Dominic Mancl Controls Engineer T: 920-759-7477 C: 920-574-0727 Trident Automation, Inc. _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
