Miguel Noya Posted May 22, 2021 Report Share Posted May 22, 2021 I'm using a PLC V430J with two adittional modules (IO-ATC8 and IO-AI8). I need to record the history of five signal (two thermocouple, and three 4-20mA sensors). Could you explain me how to do it? How could I transfer the data to a PC? Thanks Quote Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted May 22, 2021 MVP 2023 Report Share Posted May 22, 2021 Hi Miguel, there are a few ways to do this, but you need to first answer this question.......... What is the required time interval of the logging? cheers, Aus Quote Link to comment Share on other sites More sharing options...
John_R Posted May 26, 2021 Report Share Posted May 26, 2021 The best way I have used involves setting up a DT (Data Table) to hold your records, then an interval timer that is used to increment a counter which sets the row you are writing to in the DT, as well as implements the save command. The DT can then be retrieved to your PC using the DataXport utility and can be saved as a CVS or Excel file. Look at Help/Examples/Version900/Project Examples/Data Table/V570_data_log.vlp We are all happy to help, but you gotta work for it.... Work with this example and show us what you come up with, then we can all give you pointers after you figure out where you are going Quote Link to comment Share on other sites More sharing options...
