Word Bit Description
PPS07 CV High Limit Alarms
The module latches each bit when executing the subject profile segment in closed loop, and drives its algorithm CV to
maximum (100%) in an attempt to control the profile setpoint.
The module unlatches each bit when it completes execution of the subject profile segment in open loop, or in closed
loop without driving its algorithm CV to maximum (100%).
This bit
latched ON: when algorithm CV
is maximum during:
B00 Segment 1
B01 Segment 2
B02 Segment 3
B03 Segment 4
B04 Segment 5
B05 Segment 6
B06 Segment 7
B07 Segment 8
B08 Segment 9
B09 Segment 10
B10 Segment 11
B11-B15 RFU
PPS08 CV Low Limit Alarms
The module latches each bit when executing the subject profile segment in closed loop, and drives its algorithm CV to
minimum (0%) in an attempt to control the profile setpoint.
The module unlatches each bit when it completes execution of the subject profile segment in open loop, or in closed
loop without driving its algorithm CV to minimum (0%).
This bit
latched ON: when algorithm CV
is minimum during:
B00 Segment 1
B01 Segment 2
B02 Segment 3
B03 Segment 4
B04 Segment 5
B05 Segment 6
B06 Segment 7
B07 Segment 8
B08 Segment 9
B09 Segment 10
B10 Segment 11
B11-B15 RFU
