4.3 MELSEC Redundant Setting
*1 Pair number
Redundant CPU pair means the redundant CPUs (System A / System B) in the redundant system configuration.
Pair number is the number assigned to each redundant CPU pair.
Example: Ethernet connection in the RCPU redundant system (Pair No. 1 and Pair No. 2)

Precautions for making MELSEC redundant setting
Pay attention to the following items when making the MELSEC redundant setting.
• Pairing of the last station No. and station No. 1 (Example: Station No. 64 and station No. 1) is
not allowed.
• Make sure that the QCPU in the station for which MELSEC redundant setting is made is a
redundant CPU.
If any of the QCPUs to which the MELSEC redundant setting is made is not a redundant CPU,
the GOT fails to automatically change the monitoring target to the control system when the
system is switched.
• When making the MELSEC redundant setting for MELSECNET/H, MELSECNET/10, or
Ethernet connections, check the station Nos. of network modules before the setting. If the
settings of the MELSEC redundant setting and the actual network module station Nos. are not
matched, the GOT fails to automatically change the monitoring target to the control system
when the system is switched.
• GOT supports the backup mode, which is the redundant mode of the RCPU redundant system,
and does not support the process mode and separate mode.
• GOT supports the backup mode, which is the operation mode of the QCPU redundant system,
and does not support the debug mode and separate mode.
