How to Use the Node Terminal Block
Appendix 2

How to Set Controller Link Data Link Tables
When the Node Terminal block is used to send and receive data to and from the personal computer on the
Controller Link or a Loop Control Unit at another PC, the Controller Link Data Link (user setting) table (Note)
shown below must be prepared and registered (downloaded) on each node.
Note
A "Data Link table" specifies which area on the self node is to be sent and how many words are to be
received from which area on other nodes.
There are two modes of connection, connection modes 1 and 2. The connection mode is determined by
whether the connection is with only the computer on which CX-Process Monitor is running, or the connection
is also with the Loop Control Unit at another node PC.
Connection mode 1: Connection with only the computer on which CX-Process Monitor is running
Connection mode 2: Connection with the Loop Control Unit at another node PC and the computer on which
CX-Process Monitor is running
Connection mode 1) Connection with only the computer on which CX-Process
Monitor is running
