hi...
i'm newbiew about this hmi and plcs...
And...
there is this old application running on ancient "windows 3.1".
i think it's communicating with connected plc(S5) with some kind of
data or anything that i don't know...
i've checked computers Serialport activity between plc and app
with protocol analyzer. but, nothing particular...
it's only doing is always reading data from some datablock.
and writes one block(?) of data with zero sometimes.
also can't find out the sequence of reading command...
right now i'm using tty cable to connect computer and S5.
