Moran Posted November 30, 2018 Report Share Posted November 30, 2018 Hi, I'm using the PLC usp-070 and trying to use data table. I have an SD card in the PLC and: when I use the function "store DTI to file" I get error status '-31' when I use "load DTI from file" i get error status '-4' the SD card is FAT32. I'm new with UniLogic and every help will be appreciated. thanks, Moran Quote Link to comment Share on other sites More sharing options...
ORSO2001 Posted November 30, 2018 Report Share Posted November 30, 2018 hi Moran, with error -31 seams that you are trying to save "0" (zero) rows in the file...or maybe more than how many are in theDTI...you have to check the value of the "D" variable in the "Store DTI ti File" function. usually at teh first start up of my programs, when I check if a file is already present, to load the file in the DTI, and the file is not created yet, I have alarm -4...then Icreate the files where I will store DTI....then seams that you are trying to read a file that don't exist...or maybe you have insert a wrong "number" of rows to trasfer...check teh "B", "D", "E" variable in the function.
