The ITEMs for which memory is allocated depends on the function
block, but with the Basic PID Block, for example, ITEMs will be
transferred as shown in the following figure.
Allocated addresses can be output as a list in a CSV file by selecting
Execute - Create Tag File - Create HMI I/F Memory Map .
The HMI function is set in the System Common Block (Block Model
000). By default, the refresh cycle in EM0 is set to 1 s. The blocks
that are allocated are determined according to the block addresses
given to the registered function blocks.
For example, the block address will be 001 if the Basic PID Block is
pasted first. A total of 40 words (fixed) are allocated for each block
address: 20 words for send data from the Loop Controller to the CPU
Unit memory ( block address x 20, i.e., E00020 to E00039 if
the block number is 001) and 20 words for receive data from the CPU
Unit memory to the Loop Controller ( block address x 20,
i.e., E15020 to E15039 if the block number is 001).
HMI Function
This function automatically assigns
function block data (e.g., PV, SP,
and MV) in order of function block ad-
dress to addresses in the specified
bank in the EM Area of the CPU Unit
as a constant data conversion area.
