Fig. 7.15: Monitoring
The central router and bridge module acts as a standard IP router or bridge, i.e. decides to which
interface an IP packet goes next. The COM ports module does the conversion from messages re-
ceived over the serial ports to UDP datagrams and vice-versa. The Radio channel module wraps
(unwraps) IP packets into radio channel frames and handles all sorts of service frames. Terminal
servers process messages from/to virtual COM ports, transforming them into/from the same UDP
datagrams as the COM port module does. The Modbus TCP server similarly processes packets of
Modbus TCP(RTU) protocol - see the relevant application note (Modbus TCP/RTU) for details.
Since it is possible to monitor the messages from virtual COM and the resulting UDP datagrams
independently, the TSn and the Modbus TCP have two internal interfaces – distinguished as (com)
and (router).
