29 Transducer Value When Simulate Switch is set to Disable, this value
is used as the input value for the AI object. Refer to
Figure 10.1.
Disable R
30 Simulate Value When Simulate Switch is set to Enable, this value is
used as the input value for the AI object.
The input value can be changed.
--- W
51 Upper Limit Indicates the upper limit (URL) for the pressure. --- R
52 Lower Limit Indicates the lower limit (LRL) for the pressure. --- R
53 PV Range Sets the measurement range.
1. EU at 100% : Indicates input value of the upper
limit.
2. EU at 0% : Indicates input value of the lower limit.
3. Units Index : Indicates the units of the
measurement range.
4. Decimal : Indicates the digit number below the
decimal point.
EU at 100%
= 100
EU at 0%
= 0
Units Index
= kPa (1133)
Decimal
= 2
W
54 Linearization Type Select either No Linearization or Square root as a
setting of the output range.
0 = No Linearization :
Provides an output value scaled according to the
PV Range and Scale range settings.
(To use Direct with FF, set the same value for PV
Range and Scale.)
10 = Square root :
Provides a square root output computed for the
value scaled according to the PV Range and Scale
range settings.
0 W
55 Flow Constant Indicates the flow coefficient, which shows the
correlation between the flow rate value and square root
value of the differential pressure.
1.0 W
56 Lower Cutoff Specifies the low cut value. The unit is subject to
Scale.Units Index.
10 W
57 Cal Cmd Specifies the calibration method.
0 = CAL_NONE : Initial state in which calibration is
not performed
1 = CAL_LOW : Applies an actual input and adjusts
the lower limit using the value specified in
Calibration Lowest Point.
2 = CAL_HIGH : Applies an actual input and adjusts
the higher limit using the value specified in
Calibration Highest Point.
5 = CAL_CLEAR : Clears the adjustment variable.
0 (reading
value is
always 0)
W
58 Cal Status Indicates the calibration status.
0 = CAL_NONE : Start-up and default value
1 = CAL_SUCCESS : Indicates that calibration was
successful.
7 = CAL_BAD_TRIM_POINT : Indicates this status
when the adjustment variable is outside of range.
--- R
59 Calibration Highest
Point
Specifies the higher limit adjustment variable for
adjustment between two points.
--- W
60 Calibration Lowest
Point
Specifies the lower limit adjustment variable for the
adjustment between two points.
--- W
61 Calibration
Minimum Span
Indicates the minimum span of the adjustment
variable.
--- R
104 External Zero Trim Allows performing external zero adjustment.
(Trim on, Trim off)
Trim on W
105 Low Cut Mode Specifies the low cut mode.
(Linear, Zero)
Linear W
