CompactLogix Duty Standby logic

jedisaac · Aug 26, 2007

G'Day mates,

Simple one I think, need to program duty/standby logic for compactlogix in RS Logix 5000. Not quite familiar with it, used to 500. Do you have any sample programs to get me started? Just a 24 hr timer will change duty, or duty fail turns on standby.
Cheers,
Jon

I am not sure where you might be having a problem here. If you can do it in 500 then the basic logic in 5000 would be the same.
Setting the timers works a bit different. You enter 1000 for each second in the preset. Therefore if you want 24 hours, you would enter 1440000.

(60 sec / 1 min) * (60 min / 1 hr) * (24 hr) * (1000 preset / 1 sec) = 86,400,000 preset.

Thanks rd,

No wonder my 24 hour timers never worked. I don't know how to multiply.

That's actually a perfect example of why Alaric want's a 'Units' plugin for Excel. When you multiply/divide and cancel everything out, you endup with one number and one unit (hopefully, your target unit)

Thanks but it is the 5000 overall system that is slowing me down. Jus tnot used to the whole tag based structure and naming system, hope will get used to it. Again, any sample programs in 5000 would help out greatly!
Cheers,
Jon
