Re: question about interfacing between PLC and MICrocontroll
Hii,
I did the interfacing between PLC and microcontroller. I use LG PLC series Master K
and Microcontroller Basic Stamp series BS2P. At first i wanna communicate using
standar serial UART 232, but I tried to find the ladder function of this but i didn't
find it. So I did it with my way. I use Parallel interfacing ( not port parallel) but it
means it share I/O condition between PLC and Microcontroller.
example like this : my microcontroller gather sensor which require ADC for read
(because PLC with analog control is very expensive). And the micro process all the
reading and conversion and send the result to the PLC by Low or high condition in
one of the PLC I/O which will be check by PLC in ladder function.
Hope my experience will help you.
