1.4.5.1.1 Intended purpose
The communication module is for PROFINET RT communication.
The PROFINET communication module includes an internal Ethernet switch. The connection to
the Ethernet can be established directly to the communication module. An additional switch is
not necessary.
The communication module is configured via the dual-port memory by means of a system
configurator. The configuration is saved on a non-volatile Flash EPROM memory.
For use in extreme ambient conditions (e.g. wider temperature and humidity range), a special
XC version of the device is available.
