CONDITIONS

4.3.2 I/O refresh (I/O module refresh processing)

4.3.3 Automatic refresh of the intelligent function module

4 - 11

In I/O refresh, an input (X) is received from the input module/intelligent function

module, and output (Y) of the Basic model QCPU is produced to the output

module/intelligent function module.

The I/O refresh is executed before the sequence program operation starts.

During constant scan execution, the I/O refresh is executed after the constant scan

delay time has elapsed.

(The I/O refresh is executed at each constant scan cycle.)

When automatic refresh of intelligent function modules is set, communication with the

intelligent function modules of the designated data is performed.

Refer to the manual for the intelligent function modules to use for details regarding of

the automatic refresh setting of intelligent function modules.

This is a post-processing to return the sequence program execution to step 0 after

completing the whole sequence program operation processing once.
