MVP 2021 Ausman Posted August 16, 2016 MVP 2021 Report Share Posted August 16, 2016 Hi all, On my installs with single 230s, I am now needing to export large data tables automatically, or store the consecutive versions. The tables are purely logging and are set up to utilise as much memory as possible. The row number is increased by one every minute and then that row is updated with current readings. Once reaching the endpoint it zeroes and starts again. With all the parameters being logged, the table rollover occurs roughly every 36 hours. I've had a good hunt around, but can't find a way that I can store these, or send the entire table out, as an email attachment. I don't think what I need to do is possible with 230s. So....I am looking at either: 1). Changing the controllers, which will be a pain and costly, to something with microSD card onboard. But makes the storage and export easy. 2). Setup a small puter near the units running DDE to do much the same thing direct into an excel file at whatever timing suits. Would likely work ok, but is added complexity involving the puter definitely being on ok, and thus might not be as stable as a plc with SD. Reliability is paramount. 3). Send out an email often which can use as many characters as possible. But this will make things incredibly clumsy and hard to use, when trying to put it all into a graph that shows a 24 hour period. 4). Yes....I could log in every day and download the table, but this will be a pita and ultimately will cost me time and $. I don't think it possible to write a script to successfully get Visilogic to do this automatically...or should I say.... that's beyond my skills! And again, for me that means a dedicated puter needed. At present the similar logging I do with 130s, I download it every 50 days or so and once done ok, I clear things out of the SD. 5). I don't suppose there is an I/O module in the works that will let one add an SD? I can't be alone in my need and such an I/O can't be that hard to do. Or even better, a module that includes both SD and ethernet? 6). Any other bright idea someone else can think of? To me it looks like the best is going to be a controller change......bummer. cheers, Aus Quote Link to comment Share on other sites More sharing options...
