(c) Using the notification function
Because a notification mail may be sent from both the control system and standby system in either of the
following conditions, perform the process that discards the same e-mail that is received later on the receiving
side personal computer.
• The CPU operating status has been set as the notification condition.
• The device data set as the notification condition is being tracked.
*1 By setting the following SM devices as notification conditions, the system mode in the redundant system can be
identified with a notification mail. The devices can be used as conditions for identifying the system having the same
e-mail.
• SM1511 (System A identification flag)
• M1512 (System B identification flag)
• SM1515, SM1516 (operating system status)
(7) Communicating over CC-Link IE Controller Network, CC-Link IE Field Network,
MELSECNET/H, and MELSECNET/10
(a) When a redundant system is in the network
When performing access through a redundant system, change the routing parameter settings on the request
source station or relay station using the RTWRITE instruction at system switching.
(b) When performing access through a redundant system
To access another station through Ethernet using the CC-Link IE Controller Network, CC-Link IE Field Network,
MELSECNET/H, and MELSECNET/10 relay communications, set the routing parameters on the request
source station or relay station. To perform access through a redundant system, set the station that becomes a
control system as a routing station.
