Exchanging Data with the CPU Unit Section 3-3
Operation Use the following procedure:
1,2,3... 1. Register the CPU Unit I/O memory address that will be read/written from
the Loop Controller in the User Link Table.
2-1.Paste the User Link Table function block, make a software connection for
the analog value just by specifying the tag name. Data can be exchanged
with the CPU Unit's I/O memory area just by making a software connec-
tion to the analog value.
2-2.Use a contact or an analog value in the sequence table.
Data in the CPU Unit's I/O memory area can be used in a condition
expression or action expression just by specifying the tag name in the
sequence table.
When creating block diagrams with the CX-Process Tool, the User Link Table
data can be created and specified automatically within the Loop Controller if a
connection is made by virtually pasting a Field Terminal Block such as DI, DO,
AI, or AO. This method also allows the data exchanged with the CPU Unit to
be managed by tag names.
