2.6.2 Direct processing
(1) Outline of the processing
Data input and output are performed using a direct access input (DX) or direct access output (DY).
*1 Data in the Programming tool input area can be turned on or off by a test operation of a programming tool.
*2 Data in the output (Y) device memory can be turned on or off by the following operation.
• Test operation of a programming tool
• Writing data to a program
Item Description
Execution of an input
contact instruction
The OR processing is performed between the input information of the input module (1)) and the input data of the
programming tool (2)) or general-purpose input(3)). The result is stored in the input (X) device memory and is
used as input data (4)) to execute the program.
Execution of an output
contact instruction
Output data in the output (Y) device memory are read out (5)) and the program is executed.
Execution of the OUT
instruction
The operation result of the program (6)) are output to the general-purpose output and output module, and stored
in the output (Y) device memory.
