9.12 Specification of reserved station
If remote stations will be added in the future, temporary I/O numbers can be assigned.
This function allows the user to change the number of I/O points and assign I/O numbers to unconnected
station numbers so that I/O numbers in other remote stations will not be changed when a remote station is
added in the future.
→
For the reserved station specification method, refer to "Subsection 9.13.1 How to edit detailed
remote station information".
When a remote station is not connected to a reserved station number, the system does not detect
wire breakage or other errors (Reserved station flag b15 = ON).
→
For detailed Cautions on use, refer to Subsection 9.13.3.
9.13 Editing the detailed remote station information
After assigning the I/O numbers in CONFIG mode, the I/O number assignment in each station number can be
edited.
The number of I/O points can be changed, and the I/O numbers can be assigned to unconnected station
numbers for future use. Therefore, if remote stations are added in the future, it is not necessary to change the
I/O numbers in other remote stations and extension blocks/units connected to the PLC.
Detailed remote station information can be edited only in the programming software GX Developer.
→
For the edit method, refer to Subsection 9.13.1.
If a remote station is not connected to an edited station number, errors such as wire breakage may occur.
(Reserved station flag b15 = OFF)

For detailed Cautions on use, refer to Subsection 9.13.3.
