7.2 Profibus PA communication
Profibus uses a master/slave data exchange technique. The master
(typically a PLC) generates queries to individual slaves. The slaves, in
turn, reply back with a response to the master. A Profibus message
contains the information required to send a query or request, including
the slave address, function code, data, and a checksum. See
for Profibus communication parameters in case of errors.
