(factory setting)
Write Description [Setting range]
85 8085 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 rst 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”.
90 2090 RELEASE_
FAILSAFE
As specied
upon ordering
O/S Used to release the block from the fail-safe state.
When the value of this parameter is 3, writing 1
will release the block from the fail-safe state.
1 = clear, non-latch (normal state)
2 = active, latched (during fail-safe state)
3 = clear, latched (cause has been cleared but
fail-safe action is still on).
91 2091 MODEL As specied
upon ordering
— Model code
92 2092 DEV_OPTIONS 0x0000
(or 0x0001 if
PID option is
specied)
— Indicates whether any software options are
provided.
93 2093 PRESS_SENS_
INSTALLED
1 — Indicates whether a pressure sensor is equipped:
1 = equipped
2 = not equipped
94 2094 ACTUATOR_TYPE As specied
upon ordering
— Actuator type
1 = single acting
2 = double acting
95 2095 RELAY_TYPE 1 Control relay type:
1 = direct acting
96 2096 SIGN_MEAS_EXEC 1 O/S Carries outs signature measurement.
1 = off
97 2097 SIGN_MEAS_
RESULT
1 — Indicates the signature measurement status and
result.
1 = succeeded
98 2098 SIGN_MEAS_STATE 0 — Indicates the progress of signature measurement.
99 2099 SIGN_MEAS_
COUNTER
0
— Indicates the number of measured data sets. The
count is reset to zero when the power is turned off
or measurement of a new signature is performed.
100 2100 SIGN_DATA_SAVE 1 Saves the measurements of the standard actuator
signature to non-volatile memory as record data.
1 = off
101 2101 SIGN_UPLOAD_
DATABASE
1 Parameter used to specify the measured data to
be uploaded. Set this parameter, and the related
parameters will be read.
102 2102 SIGN_UPLOAD_
POINTER
0 Pointer that indicates the leading position of the
data to be uploaded from SIGN_DATA_X or
SIGN_DATA_Y, and used when there are 20 or
more data values measured.
103 2103 SIGN_DATA_X 0 — Parameter used to upload the measured
signature data (input data).
