Limit & Input configuration
« on: July 02, 2010, 05:11:49 PM »
I'm setting up a DMC-2143 board.  Using the GalilTools program, you can monitor the state of inputs, outputs, etc. 

No matter what I change, Inputs #1-8 and Home Inputs show that they are "On" (green box with a 1).  If I ground the pins, they change state (Red box with a 0), so I know I have it set in a working fashion.

However, for the high and low limits, if I click "config Galil limits active low" in the PlugIn configuration, these all change to off as the defualt state.  I click the same box for the Homes inputs, but they remain On regardless.

Is this normal?  I generally use a ground to turn inputs and homes on/active.  Is this possible with a Galil with settings, or do I have to use pull down resistors to force them low (off) as a normal state?

A bit more testing and I've discovered that when GalilTools says inputs are "On" - that means they are actually "Off".  Go figure.

Still, can the state of things be manipulated in some fashion?

Maybe you are referring to the fact that Galil usually uses negative logic for inputs, when open they  register a  1, when activated go to 0.
Nosmo.
