How to Use the Node Terminal Block
Example of connection mode 1)
System information (24 words) and Area to send to computer (512 words) are sent over the Data Link.

The Loop Control Unit uses the 1-Block Send Terminal to Computer or 4-Block Send Terminal to Computer to
send Control blocks such as PID blocks that are to be monitored on CX-Process Monitor to the Area to send
to computer.
It also uses the DO to Computer or AO to Computer block to send contacts (including parameters) or analog
signals (including parameters) to this Area to send to computer.
By the user settings of the Controller Link Data Link, a total of 536 words comprising system information (24
words) and Area to send to computer (512 words) are sent to the computer.
In this way, the following Send to Computer blocks in the Loop Control Unit are sent (allocated) to the 512
words of the Area to send to computer in Data Memory area for node terminals in order of block address (501
onwards through to 532) one function block at a time at a fixed rate of 16 words per function block. (512 words
is calculated by (max.) 32 function blocks x 16 words.)
Note A fixed number of words (512) is used even if 32 function blocks are not used.
1-Block Send Terminal to Computer (Block Model 403)
4-Block Send Terminal to Computer (Block Model 404)
DO to Computer (Block Model 401)
AO to Computer (Block Model 402)
The Control block or contact/analog signals can be monitored on CX-Process Monitor based on that data.
