Example
The PS 4-300 (master) exchanges “word” data with a
slave with CPU. The number of send and receive
bytes is defined when the stations are configured in
the Sucosoft S 40 topology configurator (See
"Topology Configuration" on page 37).
Figure 26: Configuration example for sending and receiving
communication data to/from slaves with CPU
The syntax for sending and receiving the data can be
derived from the configuration.
