GINEERS M-BUS Series Instruction Manual

- GET CONN – returns current firmware version, LAN/WAN network parameters
(MAC-address, IP-address, gateway address, network mask, connection retries and
the time between two retries) and remote reading network parameters (baud rate,
parity, message timeout).
GET MEDx – returns allowed mediums for data operator x, x=1-4. The mediums
-
can be programmed only remotely by control operator.

Instruction manual
MBET-3 is an internet/ LAN data transceiver for use in remote reading systems,
mostly m-bus. It has one RS-232C/RS-485 interface for connection to the network master
converter (like MBRS-xx) and for initial programming. The other interface is 10/100 Mbit
TCP/IP. Intended for 230Vac and DIN-rail mounting.

- protection class – IP30
- 3 LEDs (on, comm /local communication/, TX /remote communication/)
- weight – 320 g
2. MBET-3 operation
МBET-3 begins operation immediately after power-up. After initialization (about 2s),
MBET-3 enters "Command mode"/ checks for connection time, if device is set as remote
client. The connection with servers can be initiated by MBET-3 (acts as a client) or from
external network (MBET-3 acts as a server). The mode of MBET-3 is configured with service
command through RS-232/RS-485 interface. All of the contacted servers/clients must have
static real IP-addresses in order for MBET-3 to be able to connect to them (or proper routing
must be done by system administrator). MBET-3 can contact up to six servers/clients – two
"control" operators and four "data" operators. The two control servers/clients can program
all network access settings and have no access to the transmitted data. Otherwise, the data
operators can access only the data, but cannot program any network parameters. If it is
needed for an operator to have access both to the network settings and the data, its IP-
address must be set both as control and data operator. Accessible mediums for every data
operator may be programmed, so, for example, the operator which monitors water
consumption, cannot access the data, monitored by gas supplier and vice-versa.
If device is set as client, MBET-3 tries to connect to the remote servers after
predetermined period of time (default 1h). Each of the servers can accept or reject the
incoming connection. If the connection is accepted, MBET-3 starts with identification data
packet to identify the remote reading network, connected to this particular MBET-3. After
identifying the network the server can reprogram network parameters (for control operators)
or access network data (data operators). After reprogramming the parameters or gathering
the data, the server sends packet for closing the connection. After receiving this packet,
MBET-3 closes the connection and tries to connect to the next server in the list until all the
servers in the list are contacted. Then MBET-3 waits for predetermined period of time before
attempting to connect again to the first server in the list.
If the connection is accepted by the server, but then there is no communication for
predefined period of time (default 300s), MBET-3 drops the connection and goes to the next
server in the list.
