Gateway
SENTRON PAC4200 can be used as a gateway. This allows devices (slaves) that are
connected to the RS485 expansion module of PAC4200 to be connected to a device over
Ethernet (master).
Operating principle
Data sent by the master to the addressed target device: The higher-level software packages
the serial protocol into TCP/IP packets. SENTRON PAC4200 unpacks the TCP/IP packets
and forwards the freed packets of the serial protocol to the serial port (RS485).
Data sent by the addressed target device to the master: SENTRON PAC4200 packages the
serial protocol packets into the TCP protocol and forwards the packaged user data to the
higher-level software.
