iX Talk

My application requires a one-hour timer triggered by an event performed by my controller (Galil). Can I use the 'minute component of the current time' system tag to create such a timer on the T7A? I can easily display this tag in an analog numeric, but I'm not sure how to use it from there. I need to create 8 such timers.

I was planning to use the Galil internal clock to do the timing, but it rolls over to a negative value. It would seem much cleaner if I could do it on the T7A. I read the posts on using scripting to generate timers, but I'm not a C# guy.

thanks much,
Bob

You could use a iX Scheduler to do that.

Mark,

That looks promising! However, I don't want to start my timer at a set date/time, I need to start it with a controller tag trigger. Also, it's not a fixed hour timer, that's our current default time. A user enters a desired process time on the T7A.

Here's what I need:

- machine performs two processes, A and B
- user enters process B duration, from 1 - 90 minutes
- machine runs and sets a controller tag to start the timer when process B begins
- timer times out and sets a tag to have machine complete the process
- I have 8 such staggered processes running simultaneously, each needs a timer.

Can this be done with a scheduler?

thanks,
Bob

You will need to create your own timer in script then. Here is an example of how to do that.

Hi Mark and everybody else on this forum.

I have a lot of experience in software, but I'm a newbie to the world of PLC's and their HMI's and my C# leaves quite a bit to be desired, (I'm a long term ANSI C man, with a bit of C++ experience).

I've just seen this post thread and came to the last comment thinking, "YES !, this is JUST what I want".

I tried to use the link to the example, only to be told that I "wasn't authorised to use this forum".

This seems somewhat strange since it would appear that this example would be a great help to any number of people like myself who need to make use of Timers, is there a glitch on the website, or has the example been marked as private to the original poster in some way ?

I would REALLY love to see it if that is possible !!

Hopefully yours,

Peter Washington.

Hi Peter,

The link opened for me. It's in the Scripting FAQ forum...

Yes, it opens for me now too, go figure

Anyway, I've got the code snippet I was after, so I'm happy.

Thank you !
