The default value of all inputs is FALSE, which makes it possible to use only the
required number of inputs and leave the rest disconnected. The setting group
selection is not dependent on the SG_x_ACT outputs.
Table 42: Optional operation modes for setting group selection
SG operation mode Description
Operator (Default) Setting group can be changed with the setting
Settings/Setting group/Active group.
Logic mode 1 Setting group can be changed with binary inputs
(BI_SG_2...BI_SG_6). The highest TRUE
binary input defines the active setting group.
Logic mode 2 Setting group can be changed with binary inputs
where BI_SG_4 is used for selecting setting
groups 1-3 or 4-6.
When binary input BI_SG_4 is FALSE, setting
groups 1-3 are selected with binary inputs
BI_SG_2 and BI_SG_3. When binary input
BI_SG_4 is TRUE, setting groups 4-6 are
selected with binary inputs BI_SG_5 and
BI_SG_6.
For example, six setting groups can be controlled with three binary inputs. Set SG
operation mode =”'Logic mode 2” and connect together BI_SG_2 and BI_SG_5
same as BI_SG_3 and BI_SG_6.
