HI
I am trying to read some datafile from the tlserver.
I am using t100md 888.
after issuing the command
PRINT #1 <READ datefile.txt> </>
where do i find the downloaded data? Can I specify the data locations in PLC to store the downloaded data?
Thanks ::) ::) ::)

The data will be sent as CR-terminated text string to the PLC's serial port. You will need to use INPUT$(1) to read the strings one at a time. So the maximum number of characters (including CR) a file is not more than 256 since that's the size of the serial buffer. The string you read from INPUT$(1) can be stored in A$ to Z$ or converted to a number using VAL or HEXVAL if they are numeric or hex data.

You can look at the example of the <Read RTC[]> in the SynchronizeRTC.PC6 program (found in the samples\FileServer_Modem folder) which is similar except that instead of returning the data from a file it returns the real time clock as multiple strings.
