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.
Start of the ON-delay
