Word Bit Description
HPS01 Block ID = 00000100 (Low byte). High byte identical to SYS01
HPS02 See SYS02
HPS03 See SYS03
HPS04 See SYS04
HPS05, 06 RFU
HPS07 CV High Limit Alarms
For Pack Phase
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 Pack Segment 1
B01 Pack Segment 2
B02 Pack Segment 3
B03 Pack Segment 4
B04 Pack Segment 5
B05-B07 RFU
For Hold Phase
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:
B08 Hold Segment 1
B09 Hold Segment 2
B10 Hold Segment 3
B11 Hold Segment 4
B12 Hold Segment 5
B13-B15 RFU
HPS08 CV Low Limit Alarms
For Pack Phase
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 Pack Segment 1
B01 Pack Segment 2
B02 Pack Segment 3
B03 Pack Segment 4
B04 Pack Segment 5
