sysfileopen and sysfileread
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.
