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 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”.

90

2090 RELEASE_

FAILSAFE

As specified

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 specified

upon ordering

Model code

92

2092 DEV_OPTIONS

0x0000

(or 0x0001 if

PID option is

specified)

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 specified

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).
