Idx Name Byte PC Description
4 R/W Remote set point value from another block. Expressed in
PV_SCALE Unit Code
18 CAS_IN
1 R/W Remote set point status from another block
19 SP_RATE_DN 4 R/W Ramp rate for downward SP changes. When the ramp rate is
set to zero the SP is used immediately.
Expressed in PV_SCALE Unit Code per seconds.
20 SP_RATE_UP 4 R/W Ramp rate for upward SP changes. When the ramp rate is set
to zero the SP is used immediately. Expressed in PV_SCALE
Unit Code per seconds.
21 SP_HI_LIM 4 R/W The Highest Set Point value allowed.
Expressed in PV_SCALE Unit Code.
22 SP_LO_LIM 4 R/W The Lowest Set Point value allowed.
Expressed in PV_SCALE Unit Code.
23 GAIN 4 R/W The proportional gain value.
24 RESET 4 R/W The integral time constant, in seconds per repeat.
25 BAL_TIME 4 R/W The specified time for the internal working value of bias to
return to operator set bias.
Also used to specify the time constant at which the integral
term will move to obtain balance when the output is limited and
the mode is AUTO, CAS, or RCAS.
Expressed in seconds.
26 RATE 4 R/W The derivative action time constant expressed in seconds.
4 R/W The analog input value from another block's BKCAL_OUT
output that is used to prevent reset windup and to initialize the
control loop.
Expressed in OUT_SCALE Unit Code.
27 BKCAL_IN
1 R/W Back Calculation Input Status
28 OUT_HI_LIM 4 R/W The max. Output value allowed.
Expressed in OUT_SCALE Unit Code.
29 OUT_LO_LIM 4 R/W The min. Output value allowed.
Expressed in OUT_SCALE Unit Code.
30 BKCAL_HYS 4 R The amount that the output must change away from its output
limit before the limit status is turned off.
Expressed as percent of the OUT_SCALE span.
