====== Webpage Digital Output Pulse ======

This Skript will offer an additional webpage on the Web Manager HOME Page. 
You can trigger a Pulsesignal on the two Digital Outputs with a specific Length

This Way you can trigger a external Reset Signal for a device, e.g. a PC or a Measurment Device. 

The Page can also be view by restricted non-admin users.

{{ :sdk:dio.png?nolink |}}

===== Requirements =====

Please have at least NRSW [[https://share.netmodule.com/public/system-software/4.0/4.0.0.106/|4.0.0.106]] installed


===== Installation =====

Please combine this script with the sdk-startup trigger into a job
