Redundant system for Ethernet
By mounting an Ethernet interface module on each of the base units of the control system and standby system, the new
control system can continue communications if an error occurs in the control system.
(2) (3) (1)
With the redundant group setting, a redundant configuration of Ethernet networks is available. When the redundant
configuration of Ethernet networks is made, communications in the control system can be continued without system switching
if an error occurs in one network.
The redundant group setting has the following two types of settings: redundant module group setting and port group setting.
For details, refer to "Redundant System Function" of the following manual.
