5.10.2 Remote Operation for Redundant System
In the redundant system, the following remote operations can be performed by GX
Developer or other means.
(The remote operation for the Redundant CPU can be executed regardless of the
communication route.)
• Remote RUN
• Remote STOP
• Remote PAUSE
• Remote latch clear
• Remote reset
The remote operation for the Redundant CPU can be executed in any of the following
methods.
• Remote operation from GX Developer
• CC-Link IE Controller Network module, MELSECNET/H module dedicated
instruction
• Remote operation by MC protocol
• Remote operation function from OPS using EZSocket
(1) Target CPU modules of remote operation
(a) In the backup mode
1) Remote RUN, remote STOP, remote PAUSE or remote latch clear can change
the operation status of the CPU module(s) in the system or both systems
specified in the Connection Setup of GX Developer or other means.
2) Remote reset can be executed for only the control system CPU module.
Performing remote reset for the control system CPU module resets both
systems.
(b) In the separate mode
Remote operation can be performed for only the CPU module of the system
specified in the Connection Setup of GX Developer or other means.
(2) Target Specification for Remote Operation
As the target CPU module of remote RUN, remote STOP, remote PAUSE or remote
latch clear, select the CPU module of either system or the CPU modules of both
systems in the Connection Setup of GX Developer.
