64151 – 65199 Reserved
64200 – 64247 Subscription Blocks Table
These registers contain the data that allows the T2 CPU to subscribe to data on
another device on the network.
The subscription mechanism allows this CPU to “subscribe” to a block of data on
another device on the network. That block of data will be written automatically to the
specified location on this CPU on a regular basis as well as on a change of state of the
remote data.
Up to 32 subscriptions may be setup on any T2 CPU as the recipient.
(A CPU acting as a data source node may only be requested for up to 8 subscription
data blocks from other devices on the network. Data source nodes require no user set
up and operate transparently.)
A Status register monitors the performance of subscriptions, and if communication is
lost with the remote node, then an alarm can be generated.
