3-6-2 How User-defined Blocks Work

Configuration
1, 2, 3...
Groups of function blocks with analog I/O connections can be registered as a
signal user-defined block. The user-defined blocks can be saved and reused as
required (CX-Process Tool version 3.2 or higher).
Same Project or a Different Project
For example, a commonly used control method consisting of a group of function
blocks for cascade control, feedforward control, etc., and including any analog
I/O compensation and switching blocks required before and after the main
blocks, can be registered as one group. With a user-defined block like this one,
you can eliminate the need to register and connect function blocks for each con-
trol method or process. Just read in a user-defined block created in advance and
combine it with the analog I/O terminals required by the system to easily create
function block data.
User-defined blocks can be saved in files with a file name extension of .ucb.
These files can be read into other projects to enable reusing the user-defined
block.
User-defined blocks consist of the following:
1. A group of function blocks (the algorithm indicated in dotted lines in the dia-
gram)
2. A virtual block that functions as the input interface block to handle input data
for the above group of blocks
This group of function blocks
can be registered as one
user-defined block.
Function block defined by
the user (can be saved as a
file).
User-defined blocks can be
inserted or imported.
