SSC X Configuration
This ISDU is used to configure the SSC. It is possible to
set the switching logic, switching mode as well as the
hysteresis.
If the switching mode is changed, the setting of the
setpoint parameter can be adjusted:
–
If changing from Two-Point or Window Mode to Single-
Point Mode, setpoint 2 is set to 0x7FFFFFFC and
thereby deactivated. In this state or in this setting, the
setting of setpoint 2 cannot take on any other value.
–
If changing from Single-Point Mode to Two-Point oder
Window Mode, setpoint 2 is again activated and set to
the value of setpoint 1 minus the minimum hysteresis
and, in the subsequent process, can be taught to a
different value.
