The general syntax rule is as follows:

Example
The PS4-200 (master) exchanges word data with an
intelligent slave. You can define the number of send
and receive bytes when you set the station
parameters in the Sucosoft S 40 Topology
Configurator (see chapter 4, “Software
Configuration”).
Figure 24: Configuration example for sending and receiving
communication data to/from an intelligent slave
If the PS4-200 is run as slave, it provides status
bytes %ISB0.0.0.0 for device status information
and %ISB0.0.0.1 for slave status information.
These status bytes cannot be scanned together
in one word but must be addressed separately.
