Monitoring values using rslogix 5000

[secs]

Hi guys.

Just upgraded to 5000. Still getting my head around 500 but due to an upgrade of hardware new software needed.

So after some advice/suggestions/recomendations.

We have 3 outputs that drive air solonoids. We are unsure if its the solonoids being called or if its an external issue but we have an issue with the piece of equipment.

I want to monitor some outputs and record what times they are operated. Now I was going to use one of the old Redliaon G15 panels we have laying around and monitor the points and simply write them to an event log.

However is there a way I can do it with 5000 and have it write to a file or the laptop screen?

HI, I've never tried this, but I have created a timer set up to monitor cycle times and average them. Perhaps you could set a counter in the output logic, have it reset after every count, and move that info into a UDT.
There is a way to set a clock in the logic, my old boss did it very quickly one day to enable logic that had the safeties jumped out so that permissive would "expire" and not be left on when the robot guys got there. Check it out and I'll look around some more if you don't have any luck.

never used it but pretty sure 5000 has onboard trending, AFAIK it executes in the controller and can be checked with Studio5000

Why not use a FIFO and every time a solenoid output is turned on enter the time in the FIFO that way you will have a record of the output

As labeledas says, Logix 5000/Studio 5000 has trending built in. Of course, it means that you have to have the program open and online for the duration you want to trend - the trending is done at the software level, not the PLC level, and it's not saved in any sort of historical database - but if all you need is some overnight diagnostics or a bit of troubleshooting, well, that's what it's there to do!
