West Control Solutions KS98-1 - Manual (Page 249)

Inputs/outputs for PIDMA
Digital inputs:
hide
Display suppression (with hide = 1 the operating page is not displayed).
lock Adjustment locking (with lock = 1 the values are not adjustable. Function keys ID are not active).
inc Increment for manual adjustment
dec Decrement for manual adjustment
x f Sensor error x1...x3
yp f Sensor error Yp
a/m 0 = automatic 1 = manual
w/w2 0 = int./ext. 1 = W2
we/wi 0 = external setpoint 1 = internal setpoint
track 0 = tracking function off; 1 = tracking function on(r page 273, 262, 263)
y/y2 0 = output value Y1 = output value Y2
off 0 = controller switched on 1 = controller switched off
sm/hm 0 = soft manual 1 = hard manual
ostart 1 = self-tuning start r page
w stop 1 = effective setpoint freeze
gr off 1 = setpoint gradient suppression
rstart
1 = Start the setpoint ramp r the setpoint makes a step change towards the process value and goes to the
adjusted process value according to GRW+ (GRW-). The rising flank (0r1) is evaluated.
o-hide 1 = self-tuning page display suppression
oplock Blockage of key H (with oplock = 1, switchover to manual by means of key H is not possible).
Digital outputs:
y1
Status of switching output Y1; 0 = off 1 = on
y2 Status of switching output Y2; 0 = off 1 = on
c fail 1 = controller in error handling
off 0 = controller switched off 1 = controller switched on
a/m 0 = automatic 1 = manual
y/y2 0 = output value Y 1 = output value Y2
we/wi 0 = external setpoint, 1 = internal setpoint
o run Self-tuning running
o err Error during self-tuning
xw sup Alarm suppression with setpoint change
Analog inputs:
x1
Main variable x1
x2 Auxiliary variable x2 e.g. for ratio control
x3 Auxiliary variable x3 e.g. for 3-element control
Wext External
OVC+ Override control + r page 269
OVC- Override control - r page 269
Yp Position feedback
Yhm Output with hard manual
Yadd Feed-forward control
Casc Cascade input for controller cascade
ParNo Only with CONTR+; required parameter set
Analog outputs:
Weff
Effective setpoint
X Effective process value
Y Effective output value
XW Control deviation
W Internal
Yout1 Output value yout1 (heating)
Yout2
Correcting variable yout2 (cooling; only with continuous controller with split-range behaviour r CFunc=
splitRange)
Bl-no Own block number
ParNo Only with CONTR+; effective parameter set
