Protocol Adapter (PA) Setup
Within a cluster, each physical PA connects to the MQTT broker individually. The advantages of this are that messages are evenly divided between all PAs in the cluster. This increases speed and enables more devices connection. Also, if a PA stops working, the other PAs compensate by eliminating the downtime.
You can add a PA to any other PA to form a cluster. You can have an unlimited number of
PAs in a cluster, but a PA can only belong to one cluster at a time.
Note: To move a PA to another cluster, you must uninstall it from
the cluster it currently belongs to, then reinstall it on the new one.
Each PA in the cluster is able to interact with every available device on the MQTT broker. As a result, if one PA on a cluster goes down, device interaction routes to another available PA.
Note: All cluster members must be able to work with all MQTT brokers (or protocol
instances).
Note: The MQTT PA must be on the same sub-network as the device
for the Printronix single button remote control feature to function.
