3.6 Ethernet interface

The Ethernet interface of the PW100 converts the physical interface Ethernet 10/100BaseT to M-Bus and the
TCP / IP protocol to the serial protocol. The Ethernet interface is available in the front panel as an 8-pin RJ45
socket. The PW100 can be integrated into an existing local network and the M-Bus meters can be read from
one or more PCs in that network. This requires the so-called "Tibbo Device Server Toolkit" to be installed on
that PC. With this software the Ethernet interface is configured in the PW100 and a virtual COM port is set up.
This simulated serial interface enables the use of the usual M-Bus software designed for normal serial inter-
faces. Please perform the following steps of installation:
3.6.1 IT preparations
The IT division of the network containing the PW100 must define the following items:
Fixed IP address must be identical to the IP range of the reading computer. Only the last number must
▪
be different. (e.g. 192.168.1.239)
▪ You need also the subnet mask and IP address of the gateway if the IP addresses are reassigned by a
gateway.
The converter uses the port 1001 by default for the TCP protocol. This port must not be blocked by any
▪
firewall.
You can find your own IP address in your network this way:
