DIO1 Digital input/output DIO1 (11.02 DIO delayed status, bit 0). 10
DIO2 Digital input/output DIO2 (11.02 DIO delayed status, bit 1) 11
Timed function 1 Bit 0 of 34.01 Timed functions status.18
Timed function 2 Bit 1 of 34.01 Timed functions status.19
Timed function 3 Bit 2 of 34.01 Timed functions status.20
Supervision 1 Bit 0 of 32.01 Supervision status 21
Supervision 2 Bit 1 of 32.01 Supervision status 22
Supervision 3 Bit 2 of 32.01 Supervision status.23
Other [bit] Source selection (see Terms and abbreviations). -
40.31 Set 1 deviation
inversion
Inverts the input of the process PID controller.
0 = Deviation not inverted (Deviation = Setpoint -
Feedback)
1 = Deviation inverted (Deviation = Feedback - Setpoint)
See also section Sleep and boost functions for process
PID control (page 76).

0. 0
Inverted (Fbk - Ref) 1. 1
Other [bit] Source selection (see Terms and abbreviations). -
40.32 Set 1 gain Defines the gain for the process PID controller. See
parameter 40.33 Set 1 integration time.
1.00
0.10…100.00 Gain for PID controller. 100 = 1
40.33 Set 1 integration time Defines the integration time for the process PID controller.
This time needs to be set to the same order of magnitude
as the reaction time of the process being controlled,
otherwise instability will result.
Note: Setting this value to 0 disables the “I” part, turning
the PID controller into a PD controller.
