CS-series Optical Bus Controller Link Units
Appendix C
Communications Specifications
Optical Ring System
Note 1.
The maximum distance between nodes depends on the connector and cable processing methods.
2.
The CS-series PLCs do not have an LR area, but CIO 1000 through CIO 1199 are used automatically
in place of LR 000 to LR 199.
