Hi there
can anyone answer me about freeport in s7-200??
does it send just standard ascii characters?
or is it like ppi (has some kind of secret)?
if i want to communicate with another rs485 device, should i use the freeport to just send ascii characters?
if i want to communicate with the pc, then should i use a standard r2485/232 converter?
and please don't tell me to buy the pc/ppi cable
thanks in advance :site:
