How to Use the Node Terminal Block
Á
During data reception: DI Terminal from All Nodes (Block Model 414)
The self node PC receives the data that was sent from the Loop Control Unit at the other
node PC by the Controller Link Data Link. The Loop Control Unit on the self node PC uses
DI Terminal from All Nodes (Block Model 414) and AI Terminal from All Nodes (Block Model
415) to read data from the Area to receive from all nodes (on CPU Unit).
The Loop Control Units at this time can be connected only by the Controller Link. Moreover,
user settings for the Data Link must be set for the Loop Control Units.
For details, see How to Set Controller Link Data Link Tables described later in this
Appendix.
