I have to read a text file from a USB stick somehow extract the relevant data into a PLC.
The system is based around a 840DSL NCU730.3 and a MP277.
The NCU/PLC has USB ports that are described in the manual as for 'service use only' so I guess I can disregard them, which is a pity as I would have preferred to write PLC code to read the file.
So I think I'm left with the MP277 USB ports and reading the file with a HMI script, which I'm less familiar with.
Am I looking in the right direction? Will it be possible to read the file and extract the data into tags? Also is it possible to write a new file to the USB after the data is edited?
Any help would be appreciated, even if it's to tell me I'm going the wrong way.
Cheers
