6 Configuration
Self-optimization
If the "Independent controller" operating mode is enabled, self-optimization can be started at
any time, provided it is permitted in general (configuration of self-optimization). The controller
parameters determined are saved in the controller module once self-optimization is complete
and are also transmitted to the central processing unit and saved there permanently. If commu-
nication with the central processing unit is not possible, the controller parameters are saved in
the controller module only.
If the controller module changes to "Independent controller" operating mode while self-optimi-
zation is in progress, the self-optimization is aborted.
If the "Independent controller" operating mode is not enabled, self-optimization can only be
started if there is communication present between the controller module and the central pro-
cessing unit.
Manual mode
In "Independent controller" operating mode, the manual output level can still be changed in the
"Stop" system state and the actuator can be opened and closed.
Replacing the controller module
The behavior following controller module (or module insert) replacement depends on the set
operating mode and the compatibility of the software versions in the central processing unit and
controller module:
•
"Independent controller" enabled: If the software versions are incompatible, the control-
ler module starts up with its own configuration; the system itself does not start up if an in-
compatible controller module software version is detected.
If the software versions are compatible and a connection is present, the controller module
adopts the configuration from the central processing unit.
• "Independent controller" not enabled: The controller module only runs under the control
of the central processing unit. This requires compatible software versions and a connection
to be present.
Firmware update
During a firmware update, the system enters the "Stop" state and all outputs are switched off.
Afterward, the controller module starts with the factory settings, which means that the "Inde-
pendent controller" operating mode is not permitted. An "Independent controller" setting that
has been previously configured does not become active again until the configuration has been
transferred from the central processing unit to the controller module.
CAUTION!
When communication becomes possible again, the controller parameters saved in the cen-
tral processing unit are transmitted to the controller module.
The previously determined controller parameters in the controller module are overwritten.
Repeat self-optimization if necessary.
CAUTION!
A firmware update affects the controller module function.
The control is interrupted for up to 60 seconds.
Take control path out of operation during the firmware update!
