Device Loop Templet - ABB 800xA Operation

Appendix A Runtime Templates

Device Loop Templet

This section describes the active runtime fields on the Device Loop Templet. Select
the Loop FCM Display and then the device block to get the runtime version of the
Device Loop Templet. Use the fields at the bottom of the Loop FCM Display to
make State, Mode and Command changes.
LOOP DESCRIPTOR Field
This field specifies a loop descriptor. The descriptor is a label included on
operational displays and the Alarm/Event Log. This field does not need a unique
entry, so more than one loop can have the same descriptor.
Valid entry is:
PROCESSING RATE Field
This field specifies the loop processing rate. This field and the CCF BASE RATE
field interact to determine the loop processing rate. Scan Rate (Loop Detail display)
equals the Processing Rate divided by the Base Rate. If the Base Rate is 0.5 and the
Processing Rate is 1.0, then the Scan Rate is 2.0.
Valid entry is in the form of an integer equivalent of hr:min:sec. The range is 0.100
second (min.) to 65535 times the base rate (max.). Processing rate must be greater
than or equal to the CCF base rate (0.1 to 1.0). This field is automatically rounded
up to the next higher multiple of the base rate.
