Figure. 5.5.2. - 117. Simpli ed function block diagram of the SGS function.
Setting group selection can be applied by activating the SGS_SG1…SG8 inputs by the device internal
logic or connected binary inputs. Also it is possible to force any of the setting group on by enabling the
Force SG and give the wanted setting group as number from the communication bus or from local
HMI. When force parameter is enabled the local device automatic control is overridden and full control
of setting group is with user until the force SG change is disabled again.
For the application controlled setting group switch and selection is available either pulse controlled
change or signal level change options. In the setting group controller block is prioritized the setting
groups so that if higher one is controlled simultaneously with lower priority setting group the higher
request shall be taken into use.
If the control is applied with steady state signals then lower priority setting group requests will not be
applied. If pulse control is applied for the setting group selection control of the setting group has to be
applied for all setting groups e.g. if setting group 2 is selected with signal and when it is released the
setting group 1 shall not be automatically selected and the logic needs separate control to set the
active setting group back to group 1.
