Hi guys,
I'm new to PLC programming and have no knowledge about it except what I've learned in a few days. I was programming in Pascal and C+ 30 years ago and this PLC logic is breaking my brain.
If anybody can help me please? I have a program that works and all I need is to implement saving trend to SD card every time an button is pressed and it stops saving when button is pressed again.
Every time button to stop saving trend saving should be stopped and file name renamed to date+time.usd. I thing that would be nice for later checking temperatures for inspection of the process.
I created button, file for trend, SD card is formatted. Trend is working, I can see it that it is functional.
There's only one curve in one trend.
Probably I took wrong path and my logic is flawed.
Im using VisiLogic 9.8.65, Vision V430 and SD Card Suite
Edit:
I forgot to write what is the problem
Filename is not correct. I is part of original name and some numbers.
With SD Card Explorer mostly I don't see new files. And it won't backup complete SD card but only first folder (SYSTEM) or maybe five of them. Yesterday it saved whole SD card and now it only saves few parts. I restarted everything but nothing.
MB 28 is from button.
Thanks in advance!
