n+8 PILD_COMMAND RW S U8 1 N
Activation / deactivation of the
PILD algorithms
0: IDLE default value
1: GO_OFF Switch OFF the PILD algorithm
2: TRAIN Start the training phase
STOP TRAINING Stop the training phase of the algorithm before its ending
n+9 PILD_STATUS R S U8 1 D Status of the PILD algorithm
0: OFF The algorithm is Inactive (Default value)
1: NORMAL The algorithm is Active
TRAINING The algorithm is in training phase
n+10 PILD_OUTPUT R S U8 1 D Status of the Impulse Lines
Bit 0: Normal Lines Not Plugged
Bit 1: Not Valid
PILD algorithm is not working or if the training phase
didn’t produce a valid result
Bit 2: Max Pressure Deviation
The pressure value currently detected is too different from
what used for the Training. New Training necessary
Bit 3: One Line Plugged One undetected process connection is plugged.
Bit 4: Two Lines Plugged Both Process connections are plugged
Bit 5: Line H Plugged The Process connection on the high side (+) is plugged
Bit 6: Line L Plugged The Process connection on the low side (-) is plugged
Bit 7: not used
n+11 PILD_AFFECT_PV RW S U8 1 S
This parameter indicates if the
PILD algorithm must affect the
transd. block process variables
if YES and the PILD reveals an
abnormal situation it drives the
TB variables to BAD status
0 – No Doesn’t affect primary value status (default value)
1 – Yes Affect primary value status
n+12 PILD_DETECTION_TIME RW S U8 1 S
This parameter represents the length of the algorithm slot. This is the time
interval (minutes) over which the algorithm bases the decision on the
plugging state of the impulse lines
n+13 PILD_MAX_PRESSURE_DEV RW S U8 1 S
Used in the normal operation checks. It is the maximum allowed deviation
of the differential pressure from the value read in the training phase. If the
deviation is greater, than the PILD output is set to OUTPUT NOT VALID,
because the conditions are too different from the training phase
