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
