MSAC2 Interface

The communication between WAGO-I/O-PRO and the PFC run-time system
of the field bus coupler is performed via the READ and WRITE services of
the acyclic communication channel MSAC2 (Master-Slave-Acyclic Class 2).
This channel exists parallel to the cyclic data exchange MSCY (Master-Slave-
Cyclic) and has no influence on it. The program download and debugging
transmission speed is very effective, since the relevant telegrams are sent or
received in a PROFIBUS telegram. The transmission speed depends on the
physical requirements of PROFIBUS (e.g. baud rate).
