Kevin Wynne Posted February 11, 2020 Report Share Posted February 11, 2020 Hi, I am looking to use Unitronics Vision products to automate the linear accelerators at the Albany Ion Beam Lab. I first need to verify that the system will perform certain operations. I am reasonably familiar with Visilogic but I can not figure out if the system will plot a graph that is not dependent on time. I need to record and set a PWM output and then record the response from the accelerator and then graph the results. This would act like a poor mans spectrometer. The data would need to be stored, so working from a data file is ok but I can not figure out how to do this. I guess the question is; is there a simple way to accomplish this goal, and if so, how? Thank you Kevin Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted February 11, 2020 MVP 2023 Report Share Posted February 11, 2020 Which PLC model are you thinking of using? Quote Link to comment Share on other sites More sharing options...
Kevin Wynne Posted February 11, 2020 Author Report Share Posted February 11, 2020 I have a 1210, 570 and a 120 to play with. My intentions were to use the 1210 outside and a 570 connected through a fiber optic line on the inside. There is a 4,000,000 volt difference between regions.

MVP 2023 Flex727 Posted February 11, 2020 MVP 2023 Report Share Posted February 11, 2020 You can record data in either a Data Table onboard the PLC or on an SD card. On the SD card you can store the data directly from a Data Table in a format that can be read by Unitronics SD Card Suite and converted to .csv. You can also (with more difficulty) store the data directly to the SD card in .csv format. My recommendation would be to store the data in a Data Table and periodically push it to the SD card. You can read the file on the SD card directly (using SD Card Suite) without removing the card if you can go online with the PLC. Unitronics SD Card Suite is free and easy to use.

Kevin Wynne Posted February 11, 2020 Author Report Share Posted February 11, 2020 I think that I left out a key point here, I need to display the graph of ( current Vs B Field) on the PLC itself, it is a part of the run up procedure and can not be done off line.

MVP 2023 Flex727 Posted February 12, 2020 MVP 2023 Report Share Posted February 12, 2020 Ugh. I think that's going to be a problem. Quote Link to comment Share on other sites More sharing options...
Kevin Wynne Posted February 12, 2020 Author Report Share Posted February 12, 2020 I understand that live streaming the data into a trend is out but is there any way to plot data from a file or data base shortly after acquisition? Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted February 12, 2020 MVP 2023 Report Share Posted February 12, 2020 It only takes a few seconds to go online with the PLC, copy the data out of the Data Table, paste it into a spreadsheet, and graph it any way you like.
