Hello,

So yesterday was learning UIAlphaEntry and although I am not fully there I feel better about where I am going with this.

So I have checked to see if Auto1 is the dig input 5 and it is. However no matter how I try it I cannot get the di5 to make good and I keep getting the “Unknown Identifier”

In a nutshell.

We change blades every 1400 parts, I have 3 in for my counters at the moment.

at 1400 parts I want the controller to stop operation

the tech must login to clear Blade Change Request, this will give them ownership of the blade change.

After the login they can reset the robot and startup.

Lemster really helped to get me here with this however I figured I would ask the community so as to not bug him/her to death, lol.

Have a wonderful day and God Bless,

Joey

You need to use your configured, named instance of digital input 5. What it is named in your EIO.

Lem,

You know you’re top notch, right?

I actually had this figured out last night while at dinner sitting in front of my computer. I just want you to know that I really appreciate your help with all of this.

God Bless,

Joey
