Extended Processing FCM Appendix A Runtime Templates280 3BUR002418-600 AExtended Processing FCMThe Extended Processing FCMs perform mathematical functions on data gatheredover an extended period of time. These FCMs provide information for historical,long-range evaluation of a process, rather than for direct operational control.This section describes the active runtime fields on the following extendedprocessing FCM templets. See below for common runtime fields.• Continuous Moving Average FCM• Standard Deviation FCM• Non-Rate Periodic Total FCM• Periodic Average FCM• Periodic Maximum FCM• Periodic Minimum FCM• Periodic Rate Total FCMCommon FieldsINITIAL MODE FieldThis parameter specifies if the output mode of the FCM is set at MAN (manual) orAUTO.INITIAL OUTPUT FieldThis parameter specifies the result of the FCM calculations and can be changed ifthe output mode is manual. There are no state values nor state mnemonics availablefor TCL for this parameter.BAD INPUTS ACCEPTED? FieldThis field specifies the data qualities acceptable for the input signal to the FCM andthe action to take if the data quality becomes unacceptable. Valid entries are:YES GOOD and BAD are acceptable data qualities
