PARAMETER_NAME
Input Lo
IN_LO
15
The value used for input whenever IN is below
range.
Input 1
IN_1
16 The first analog input value and status.
Input 2
IN_2
17 The second analog input value and status.
Input 3
IN_3
18 The third analog input value and status.
Range High
RANGE_HI
19 The high limit for IN.
Range Low
RANGE_Lo
20
The low limit for IN. If IN is less than
RANGE_LO, then IN_LO is used.
Bias Input 1
BIAS_IN_1
21 The bias value for IN_1.
Gain Input 1
GAIN_IN_1
22
The proportional gain (multiplier) value for
IN_1
Bias Input 2
BIAS_IN_2
23 The bias value for IN_2.
Gain Input 2
GAIN_IN_2
24
The proportional gain (multiplier) value for
IN_2
Bias Input 3
BIAS_IN_3
25 The bias value for IN_3.
Gain Input 3
GAIN_IN_3
26
The proportional gain (multiplier) value for
IN_3
COMP_HI_LIM
27 High limit for the compensation term.
COMP_LO_LIM
28 Low limit for the compensation term.
ARITH_TYPE
29
Selects the computation to be used as the
block function.
BAL_TIME
30
The time to balance OUT to PRE_OUT after the
block enters Auto mode. It has no effect after
the time expires.
BIAS
31 The bias value.
GAIN
32 The proportional gain (multiplier) value.
Output High Limit
OUT_HI_LIM
33 The maximum output value allowed.
Output Low Limit
OUT_LO_LIM
34 The minimum output value allowed.
UPDATE_EVT
35
This alert is generated by any changes to the
static data.
Block Alarm
BLOCK_ALM
36 Dynamic
Data Type: DS‐72
The read‐only data for an alarm generated by a
change in BLOCK_ERR.
