Configuration of Function Blocks Section 3-1
3-1 Configuration of Function Blocks
All Loop Controller functions can be achieved by connecting the function
blocks in the software.
3-1-1 Configuration of Function Blocks
Function blocks comprise data items called ITEMs each starting from 000.
ITEMs 000 to 004 are common to all function blocks.
ITEM006 and onwards differ according to the Block Model.
3-1-2 Preparing Function Block Data Sheets
CX-Process Tool is used to set data to each item in each function block, and
prepare function block data sheets. Function blocks are registered to function
block data sheets by being allocated to a block address (address for execu-
tion). These function block data sheets need only be transferred (downloaded)
to the Loop Controller to enable use of the Loop Controller. Function block
data sheets are prepared as function block files appended with the .ist exten-
sion.
Note When the Loop Controller is shipped from the factory, function block data
sheets are not stored on the Unit. Be sure to prepare function block data
sheets using CX-Process Tool and transfer (download) the sheets to the Loop
Controller.
Follow the procedure below to prepare and download function block data
sheets.
1,2,3... 1. Allocate the function blocks to block addresses.
Select the function blocks to be used, and allocate them to block address-
es in the function block data sheets. Function blocks become executable
data once they have been allocated to block addresses. Allocatable block
addresses are determined as follows according to the type of function
block. Block addresses other than these cannot be allocated.
