Serial data from PLC to file, is VB the tool ?

Serial data from PLC to file, is VB the tool ?

(OP)
Hi, as a PLC programmer with no (yet) experience of VB, I could do with some guidance. I have an app to develop that will take an ASCII text string (from a PLC) from the serial COM port and save it as a file, the file name being sequentially numbered (0000-9999) with a .prd extension. Once at 9999, the filename reverts to 0000 and over-writes the old files.

One text string in on the COM port approx every 5 minutes.

RE: Serial data from PLC to file, is VB the tool ?

VB has a serial port communication tool (MSCOMM control) which takes serial data into your program. Saving a file and incrementing your file name are also very straightforward

Good Luck
