CREATING A HARDWARE LOGIC
This chapter describes how to create a hardware logic.
9.1
Main Blocks in the Hardware Logic Outline
Window
With the flexible high-speed I/O control module, various controls are possible by arranging multi function counter blocks and
various function blocks and linking these blocks.
In the hardware logic outline window, all of external input blocks, Y device terminals, and OUT terminals are arranged in the
first section and all of external output blocks and SI device terminals are arranged in the fifth section when a project is stated.
No blocks are arranged in the second to fourth sections. Arrange blocks and link them according to the control to be executed
with the flexible high-speed I/O control module.
(1)
The following table shows sections where each main block can be arranged and the number of blocks that can be arranged in
each section in the hardware logic outline window.
Section Item name
First section External input block
Y device terminal
OUT terminal
Second section Parallel encoder block
SSI encoder block
Third section Multi function counter block
Fourth section Logical operation block
Fifth section External output block
SI device terminal
*1 The number in () indicates the number of blocks that are arranged by default and no additional blocks can be arranged.

General command 0 to General command F (Y10 to Y1F) can
be used as input signals.
Output signals from external output blocks in the fifth section
can be used as input signals for the first section.
