Exchanging Data with Function Blocks

Loop Control Unit
52
The function blocks listed in the following table must be registered/connected
in the Loop Control Unit/Board in order for the Monitor Plus Software to
access data in the Loop Control Unit/Board. Data is exchanged using the
function blocks and the tags set in those function block.
There are 4 possible cases, as shown in the following table.

Each function block's ITEM list indicates which ITEMs will be read or written.
(An ITEM will not be read or written if "–––" is indicated for the R/W Mode in
the According to HMI or According to Monitor Plus columns.)
This section explains how to use Monitor Plus to read and write data in func-
tion blocks within the Loop Control Unit or Board.
Monitor Plus can be used to set function block data with Receive All Blocks
(Block Model 461) and monitor function block data with Send All Blocks (Block
Model 462).
Setting Function Block Data from Monitor Plus
Monitor Plus writes data directly to the specified function block's tag. The
Receive All Blocks (Block Model 461) function block must be registered in
advance.
