Digital selector
No selection
Signal (high-active) for changeover from parame-
ter block 1 to parameter block 2
Controller signal on Digital selector
No selection
Signal (high-active) for switching on the controller
Controller signal off Digital selector

Parameter Selection/text/value Description
Parameter Selection/text/value Description
Method Step response Step response method
Oscillation Oscillation method
Inhibit
(setup only)
Enabled Autotuning is enabled.
Inhibited Autotuning is inhibited.
Controller output type 1 Type of the first controller output
The cycle time is calculated on the basis of the
type of controller output.
Automatic Automatic setting based on the configuration
If the controller output signal is assigned to several
digital outputs (e.g., output 1: relay; output 4: log-
ic), the digital output with the smaller number is rel-
evant (here: output 1).
Relay Relay output
Analog Analog output
Solid state/logic PhotoMOS® relay output or logic output
Controller output type 2 (like output type 1) Type of the second controller output (for three-
state controller)
Standby output -100 to +100 (0) Output level (in percent) at start of autotuning for
step response method
Step size 10 to 100 (30) Size of output level step (in percent) for step re-
sponse method
Application of switching
period
Application of Cy cycle time after completion of au-
totuning
Off The determined value will not be applied.
On The determined value will be applied.
Start/stop signal Digital selector
No selection
Signal (active for rising edge) for starting and stop-
ping autotuning
Autotuning is started by a rising edge. If autotuning
is active, it is stopped by a rising edge.
Inhibit signal Digital selector
No selection
Signal (high-active) for inhibiting autotuning
