Starting the ON-delay time via IO-Link

The ON-delay time can also be started through the process image of the outputs (PIQ) by

setting the control command "Start ON delay time." This is a simple method of permitting

brief load steps during operation if these are predictable.

The ON-delay time can be set either locally via the three keys on the device, or via IO-Link.

The requirements governing the starting of the ON-delay time (Power-ON, manual reset

and/or restart) can only be modified via IO-Link.

Note

After exiting the menu level SET, the ON-delay time starts again.
