3.6.2Response delay in refresh system

This section describes a delay of an output change in response to an input change. An output change in response to an input change has a delay of up to two scans as shown in Fig. 2.6.

Ladder example

In this ladder, output Y1E turns on when input

X5 turns on.

			(Minimum 1 scan)

The Y1E output turns on earliest when the control input terminal turns from OFF to ON immediately before a refresh. X5 turns on at an input refresh, Y1E turns on at step 0, and the control output terminal turns on at an output refresh after execution of the END instruction.

In this case, therefore, a delay of a control output terminal change in response to a control input terminal change is one scan.

The Y1E output turns on latest when the control input terminal turns from OFF to ON immediately after a refresh. X5 turns on at the next input refresh, Y1E turns on at step 0, and the control output terminal turns on at an output refresh after execution of the END instruction.

In this case, therefore, a delay of a control output terminal change in response to a control input terminal change is two scans.
