time, depending on the amount of data and the complexity of the program. This
means that the standby CPU’s data may be some cycles behind the active
CPU. “Program Cycle” will transfer the data on every program cycle and wait
until the data is sent. 100ms..1000ms specifies the minimum times between
data transfers. If the cycle time is longer than this time, then the cycle time is
used instead. Actual data synchronization times can be seen by using the web
page of the active CPU0.
Switchover XOB number
Fixed as XOB 31. If programmed, this XOB is executed on CPU1 when the
Standby PCD takes over control of the system and becomes the Active PCD.
Ethernet Port IP Settings
The Redundant CPU1’s Ethernet IP ports are also configured from here.
Primary CPU1 IP Address
The IP address of CPU1 in the Primary device. This IP address is used to
transfer the synchronization data between CPU1 in the Secondary device, and
CPU1 in the Primary device.
Secondary CPU1 IP Address
The IP address of CPU1 in the Secondary device. This IP address is used to
transfer the synchronization data between CPU1 in the Primary device, and
CPU1 in the Secondary device.
Subnet mask and Default gateway
CPU1’s subnet mask and default gateway. The Ethernet settings for CPU0 are
done from the Device Configurator of the primary and secondary devices.
