Node Terminal block data is allocated to the Data Memory for the Node
Terminals following the system information.
The Node Terminal block data is exclusively for data exchange with CX-
Process Monitor and with Loop Controller Units at other nodes.
The Loop Control Unit sends and receives data to and from this area by
specific function blocks.
The following table describes an overview of exchange of Node Terminal
block data.
