• When an input contact instruction has been executed:
The input module's input information 1) is ORed with GX Developer input area's input
information 2) or remote input refresh area data, and the result is stored into the input (X)
device memory. Then this data is then used as input information 3) at sequence program
execution.
• When an output contact instruction has been executed:
Output information 4) is read from the output (Y) device memory, and a sequence program
is executed.
• When an output OUT instruction has been executed:
The sequence program's operation result 5) is output to the output module, and is stored in
the output (Y) device memory.

* 1 : The input area for GX Developer can be turned ON/OFF by:
• Test operation using GX Developer
• Write from network module
* 2 : The area for the device memory output (Y) can be turned ON/OFF by:
• Test operation using GX Developer
• Link refresh of CC-Link IE controller network
• Link refresh of MELSECNET/H network system
• Write from external device using MC protocol
• Automatic refresh of CC-Link
* 3 : The remote input refresh area indicates the area used when automatic refresh setting is made to
the input (X) with CC-Link IE controller network, MELSECNET/H and CC-Link.
Automatic refresh of the remote input refresh area is performed during END processing.
