POINT
1: Set Total stations and common parameters of the multiplexed remote sub-
master station when using the multiplexed remote sub-master station to
resume the network. The settings must be the same as those of the
multiplexed remote master station.
For example, if the multiplexed remote master station is powered off and then
on during network control by the multiplexed remote sub-master station, the
multiplexed remote sub-master station resumes networking as a master
operating station.
2 : Default values are not set in LX/LY. Set the refresh parameters.
3 : Default values are preset for LB/LW.
The system may operate even if refresh parameters have not been set.
For the operation and precautions, refer to Section 5.1.5 (3).
4 : Refer to the Q Corresponding MELSECNET/H Network System Reference
Manual (PLC to PLC Network) (SH-080049).
