Mechanism for reading data from CX-Process Monitor
CX-Process Monitor uses the data in the Area to send to computer on the
CPU Unit to read data from the Loop Control Unit.
To send data on the Loop Control Unit to this Area to send to computer, the
data to be monitored must be specified by the Send to Computer blocks.
CX-Process Monitor uses a symbol for handling user-defined data called a
"tag number" (a fixed name for each ITEM in each function block called a
"tag ITEM") to specify the data to be monitored.
Note The following table shows the data that can be monitored or set on CX-
Process Monitor.

1: This data cannot be registered to the Tuning screen by the 4-Block
Send Terminal to Computer block (Block Model 404).
Â
2: This data can be monitored by re-issuing the data to the network.
So, the following three operations must be performed to use CX-
Process Monitor. Each of these operations is executed on CX-Process
Tool.
