Parameters
Default
Here are reported the default values for the input/output parameters:
OCRB
Defines the zone across the setpoint where the PID algorithm is not
affected by the overshoot control
ACT_TYPE Selection of the control output direction: direct or reverse.
DTRK Tracking Operating mode Command
TRK Tracking signal value
DAM Automatic/Manual Operating Mode Command
AM_VAL Manual Value [0…100.0]
DAUX Auxiliary Operating mode Command
AUX Auxiliary signal value
PV_LO Lo Span of the Process Value
PV_HI Hi Span of the Process Value
OUTLO
Lo value for the PID output. This limit is active always except for the
manual movements of the output (i.e. DAM active).
OUTHI
Hi value for the PID output. This limit is active always except for the
manual movements of the output (i.e. DAM active).
OUT Controller Output Value.
TPB Pb calculated from the tuning algorithm
TTI Ti calculated from the tuning algorithm
TTD Td calculated from the tuning algorithm
AT_STS This output is true during tuning activities
AT _ FA I L
This output is set to false at the tuning process beginning and is set
to true if tuning process fails
Parameter Description
Input Default Value
PB
These parameters must be connected with an external variable.
For this reason, the default value is the one specified as initial.
Please note that, in any case, internally the PID actions are limited
by these ranges:
PB : 0.5... 1000.0
TI : 1.0... 6000.0 - the value 0.0 is allowed to exclude the
integral action
TD : 0.5... 600.0 - the value 0.0 is allowed to exclude the
derivative action
