sysfileopen and sysfileread

Good morning.

I have to read an external file .csv (or .txt).

I use AB 1.2 and my PLC is an PM572 (modbus).

I use the function "sysfilopen" and "sysfileread", but don't work.

I have cheched path..etc..etc... but on sysfileopen output there is always "0" and the sysfileread, consequently, doesn't read.

Thanks for the tips.
