I/O control mode
The I/O control mode for QnACPU is refresh mode (direct I/O is enabled depending on the
device).
• As the I/O control mode for AnACPU and AnUCPU is the refresh mode as with
QnACPU, there are no problems with the input timing of inputs (X) or the output timing
of outputs (Y).
• In the case of AnCPU, AnNCPU, and A3HCPU, I/O control mode is fixed or selected
to direct mode, and the input timing for inputs (X) and output timing for outputs (Y)
differs from that for the refresh mode.
The I/O control mode for each CPU module is shown below.
• Modifying programs that generate pulses from SET/RST instructions by using direct
devices
Modify programs which, in the direct mode, output pulse output to the external using
SET/RST instructions to programs that use direct output devices for QnACPU.
Model Name
I/O control Method
AnCPU
Fixed as the direct mode
AnNCPU
Direct mode or refresh mode ia selected with the switch on the module.
A3HCPU
Direct mode or refresh mode is selected by parameter settings.
AnACPU
Fixed as the refresh mode
AnUCPU
Fixed as the refresh mode
