Conext ComBox Master-Slave Configuration
Overview
The ComBox can be set up in a master-slave configuration to monitor multiple
separate Xanbus networks and supported Modbus devices, such as power
meters. This configuration can be used for large multi-cluster systems as well as
smaller systems when devices need to exist on separate ComBoxes.
Using a Master-Slave Configuration, multiple Xanbus networks on separate
ComBoxes can be combined and monitored through the Master ComBox. When
multiple ComBoxes have been added to the system, the settings of the slaves
can be controlled and modified by the Master ComBox. Data is reported by the
Slave ComBox to the Master ComBox. The Master ComBox is for data
aggregation only and has no Xanbus or Modbus devices attached directly. RS-
485 devices and principal devices such as XW+, AGS, SCP, etc. are placed on
one of the slave ComBoxes.
A sample master-slave configuration is provided below.
Note: This diagram is an example for illustration purposes only and is one of
many possible configurations.
