which controller to use???
« on: June 23, 2016, 08:50:59 PM »
Hello everyone,

I need to create an application that requires the controller to store some data to be used in a trending chart later. has anyone done this? which would be the best controller for this purpose.

Thanks

Hi Diego,
It's very much depends on how many points of data you need to store, is it 10 counters for different events, or is it a continuous running log of many values?
Clarifying these questions will help finding an answer to your actual question.

the controller should be able to log continuously up to 20 variables.
I have used a SC 050 020 controller in the past, if fact I have a spare one that I was hopping I could use.
thanks,

Hello Diego,

Over what time periods did you want to be able to store the logged data of these 20 variables?

You'll want to do the math on how much data you need to store.  That will require understanding the variable size (8-bit, 16-bit, 32-bit...), how often you wish to log these variables, and how long you wish to keep these variables stored before they can be erased.  You've posed the question in a very generic way.  At the very least you need a count of inputs and outputs and signal types before a controller can be recommended.  I'd recommend looking up some of the 'Extended Memory' controllers from the PLUS1 series for any sort of data logging.
