2.6 Processing of Inputs and Outputs 2.6.1 Refresh processing
*1 The Remote input refresh area indicates the area to be used when auto refresh is set to the input (X) in the CC-Link.
Data in the remote input refresh area are automatically refreshed during END processing.
*2 Data in the Programming tool input area can be turned on or off by a test operation of a programming tool.
*3 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
*4 This applies only to the L26CPU-BT.
Item Description
Input refresh
Before program operation, input data are collectively read out from the general-purpose input and input modules
(1)), the OR processing with the Programming tool input area and Remote input refresh area is executed, and
then the data are stored in the input (X) device memory.
Output refresh Before program operation, data in the output (Y) device memory (2)) are collectively output to the output module.
Execution of an input
contact instruction
Input data in the input (X) device memory are read out (3)) and the program is executed.
Execution of an output
contact instruction
Output data in the output (Y) device memory are read out (4)) and the program is executed.
Execution of the OUT
instruction
The operation result of the program (5)) are stored to the output (Y) device memory.
