Bit-mapped Status Words
Word Bit Description
OPS01 Block ID = 00000110 (Low byte). High byte identical to SYS01.
OPS02 See SYS02
OPS03 See SYS03
OPS04 See SYS04
OPS05 Open
OPS06 Open
OPS07 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%).
When this bit
is latched ON: algorithm CV
is maximum during:
B00 Segment 1 (First Clamp Open)
B01 Segment 2 (First Clamp Open)
B02 Segment 3 (First Clamp Open)
B03 Segment 4 (Second Clamp Open)
B04 Segment 5 (Second Clamp Open)
B05 Segment 6 (Second Clamp Open)
B06 Segment 7 (Third Clamp Open)
B07 Segment 8 (Third Clamp Open)
B08 Segment 9 (Third Clamp Open)
B09 Segment 1 (Clamp Open Slow)
B10 Segment 2 (Clamp Open Slow)
B11-B15 Open
OPS08 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%).
When this bit
is latched ON: algorithm CV
is minimum during:
B00 Segment 1 (First Clamp Open)
B01 Segment 2 (First Clamp Open)
B02 Segment 3 (First Clamp Open)
B03 Segment 4 (Second Clamp Open)
B04 Segment 5 (Second Clamp Open)
B05 Segment 6 (Second Clamp Open)
B06 Segment 7 (Third Clamp Open)
