Description
Active/Passive mode can be changed manually. The Active device
communicates with the host system and responds to requests for measurement
data, status information, and diagnostics. This option can be useful for testing
that both system hubs function properly as Active and Passive.
If the status is OK, a green check box is displayed. Otherwise a list of warnings
and errors will be displayed.
Each device has a unique identification number which can be used, for example,
when setting up Modbus addresses.
The redundant system hubs can be given individual Modbus addresses in case
you need to be able to communicate separately with each system hub.
Number of times that the Primary and Backup devices have changed to active
state, as well various error messages and warnings.
It is possible to un-pair the two devices in the redundancy system by using the
Switch to Standalone Mode button. When un-pairing the system, the active
device will change mode to standalone. The passive device will load the default
configuration database (CDB) and the default communication parameters
(including Modbus address 245) to make sure it will not disturb communication
on Host and Field ports after un-pairing the system hubs. Consequently, the host
system will lose contact with the backup device until proper communication
settings are reset.
This button lets you configure specific redundancy options such as fail-over,
take-over, and passive device communication. See
