Parameters of Transducer Block
Function Block Parameters
81 2081 TOTAL_
CLOSE
_TIME
0 hour Total time where valve position is equal to or
less than OPEN_CLOSE_THRESHOLD. To
reset the count, write 0.
82 2082 OPEN_
CLOSE
_
THRESHOLD
0.25% — Threshold value for TOTAL_OPEN_TIME and
TOTAL_CLOSE_TIME.
83 2083 OPEN_TIME_
LIM
2^32-1 hours High-limit alarm setting for
TOTAL_OPEN_TIME.
When TOTAL_OPEN_TIME has reached this
setting, a block alarm is generated.
84 2084 CLOSE_TIME
_LIM
2^32-1 hours High-limit alarm setting for
TOTAL_CLOSE_TIME.
When TOTAL_CLOSE_TIME has reached this
setting, a block alarm is generated.
85 2085 TOTAL_
NEAR
_CLOSE_TIM
0 O/S Total time period when the valve position is
equal to or less than the value set in
NEAR_CLOSE_THRESHOLD (judged as
when the valve is nearly closed). To reset the
count, write 0.
86 2086 NEAR_
CLOSE
_
THRESHOLD
3.0 % Threshold for judging that the valve is nearly
closed
87 2087 NEAR_
CLOSE
_TIME_LIM
2^32-1 hours High-limit alarm setting for
TOTAL_NEAR_CLOSE_TIM. When
TOTAL_NEAR_CLOSE_TIM has reached this
setting, a block alarm is generated.
88 2088 DEVIATION_
LIM
110% Deviation high limit (%)
89 2089 DEVIATION_
TIME
_TH
10, -1 (off) If the time period when the deviation is
continuously equal to or greater than
DEVIATION_LIM has reached the time set for
the first value in this parameter, a block alarm
is generated. If it has reached the time set for
the second value, the instrument transfers to
fault state. Negative value means off.
