Hi!
A customer has a weighing machine and wonder if he can read the results thorugh their communication port. I have never done ASCII before and have a few questions.
They state that the communication is:
Baudrate 9600
Databits 8
Parity None
Stopbits 1
Protocoll is ASCII based
They don't state what connection they send it through they just say it's a "COM PORT". Musn't I know this too? To know what module I have to buy to the s7-1200 to recieve the signal?
They say the protocoll is ASCII based, what does that mean? Is ASCII a protocoll of it's own or do I send it over for example modbus?
The data to be sent is in this format:
weigh+c+cr+if
I guess this is some sort of information, I will have to ask them some more of what it contains.
And last, what block in TIA portal is used to get ASCII from a slave?
