1: This setting is necessary when the CPU module installed with a network module is a Redundant CPU.
2: Default values are not set for LX/LY. Set 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 5.7.2 (3).
: Set at all times (no default setting).
: Set at all times (default setting provided).
