Devices used in the program are shown.
Each of the local modules is mounted in the position represented by the following
I/O No.
• Local module of local station No.5 (X/Y220 to X/Y23F)
• Local module of local station No.6 (X/Y240 to X/Y25F)
• Local module of local station No.7 (X/Y260 to X/Y27F)
* 1 The range of device use varies depending on the link parameters of the master station.
* 2 Can be replaced with other devices as necessary.
However, to avoid wrong replacements, we recommend using the program examples described in
the manual without changes.
