7 Setpoints
Setpoints are analog, binary or special data objects which are used for adjusting the controller to the
specific environment. Setpoints are organized into groups according to their meaning. Setpoints can
be adjusted from the controller front panel, PC, MODBUS, etc.
7.1 Password protection
Each setpoint can be protected by a password against unauthorized changes. Password protection
can be assigned to the setpoints during the configuration procedure. See the chapter Operator guide
for instructions on how to enter and modify a password. See also the LiteEdit help to learn about
working with a password in LiteEdit.
7.2 Setpoint synchronization
Setpoints marked with a “#” sign at the beginning of their names are synchronized with other
controllers present on the CAN bus line, i.e. the system will ensure that the respective setpoint will
have an identical value in each connected controller. If the setpoint is changed in one controller, the
same change will occur in all other controllers. This function is necessary especially for MINT
application, where the system of Power management is based on fact that the respective setpoints are
identical in all controllers.
All parameters marked as shared (“#”) are overwritten during archive download in case there is no
another single controller visible on the CAN bus. In case there is another controller on the CAN bus,
the shared parameters are not overwritten.

10. Volt/PF Control
11. ExtI/O Protect
12. SMS/E-Mail

15. Sensors Spec
CAUTION!
Do not write setpoints repeatedly (e.g. power control from a PLC by repeated writing of baseload
setpoint via Modbus) The setpoints are stored in EEPROM memory, which can be overwritten up to
10
5
times without risk of damage or data loss, but it may become damaged, when the allowed number
of writing cycles is exceeded!
