Use NI Max to generate a port line (i.e. port 1, line0) toggling square wave?

[BCES]

Is there a way to internally set up an NI Max Task to generate a port line toggle (i.e. port1, line0) as a toggling square wave?   

I know I can do this manually in NI Max by manually clicking on the port1 line0 output pin.  There must be a way to set this up as a task and have it run.   This doesn't even have to run continuously, just a few seconds toggling at about 1 time per second.

Any hints or suggests or an example that might show how to do this would be greatly appreciated

Sounds like a job for a counter. Or you can write a program that controls that line however you need.

The key request here is "internally":  I want to use NI max alone to have this square wave generated-- while I use NI Max to read other analog inputs and generate other analog outputs.

It turns out this would be necessary for troubleshooting other (external to the NI board) circuits as that square wave would enable them.
