consists of a binary input circuit (BI1), a number generation function ('Binary selection'
provided in basic functions of the PLC editor), and the signal reception point. That is, when
the B1 switch is closed, a signal enters the BI1 circuit and is carried to the Binary selection;
accordingly the Binary selection, which is programmed to generate a group number '2' in UNIT
when signal '1' is injected in BOOL(BIT), can generates and inject the group number '2' at the
'PLC_Group_ENUM'. Consequently, the Setting function (201400) starts change the group
from number '1' to '2'. Note that changing is only performed during the BI1 is closed in the
example logic; hence, the setting number goes back to '1' when the BI1 is open.

Note: Function block for the binary input circuit (Binary input FB) is provided in User
1
library of PLC editor. See the Chapter
"Programmable Logic Controller and PLC editor"
Note: The SEL and RS functions are the basic functions. In the logic, when signal '1'
2
enters the SEL function, value '2' is generated. For more information, see the help
menu on the PLC editor.
Note: For your reference, changing to group3 is performed when value '3' enters. In
3
other words, values '1' to '8' correspond to 'group1' to 'group8', respectively.
Note: This example is designed to change 'group1' to 'group2' or 'group2' to 'group1'.

Figure 4.8-3 exemplifies that selecting a group among eight groups is required by the
usage of three BI circuits (i.e., Group 1→Group2, Group3,... Group8).
