2. MBET-3 operation
МBET-3 be ins 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 confi ured with service
command throu h 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 routin
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 pro ram
all network access settin s and have no access to the transmitted data. Otherwise, the data
operators can access only the data, but cannot pro ram any network parameters. If it is
needed for an operator to have access both to the network settin s and the data, its IP-
address must be set both as control and data operator. Accessible mediums for every data
operator may be pro rammed, so, for example, the operator which monitors water
consumption, cannot access the data, monitored by as 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
incomin connection. If the connection is accepted, MBET-3 starts with identification data
packet to identify the remote readin network, connected to this particular MBET-3. After
identifyin the network the server can repro ram network parameters (for control operators)
or access network data (data operators). After repro rammin the parameters or atherin
the data, the server sends packet for closin the connection. After receivin 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
attemptin to connect a ain 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 oes to the next
server in the list.

If the device is set as server, it just waits for remote connections on specific local port.
By default port is set 59615 (a free port). When connection request arrives, MBET-3 checks
its internal list of IP addresses for allowed operators and decides to accept or reject the
connection. If there is no communication with the remote client for predefined period of time
(default 300s), MBET-3 closes the connection. If one of IP addresses is set 0.0.0.0 - then
MBET-3 accepts connections from anywhere and does not check the incomin request IP
address.
Initial parameters pro rammin is essential and includes settin the LAN/WAN-network
parameters (IP-address, ateway IP-address, network mask, IP-address of the control
server, etc, includin settin new MAC-address if MAC-conflict occurs) and remote readin
network parameters (baud rate and parity of serial connection, remote readin network
number). These parameters must be set first, and after successful connection all the
parameters can be set remotely by the server.
Direct pro rammin of the parameters can be done with simple terminal pro ram (like
GiCom) or by special software. When usin terminal pro ram, the parameters are set as
follows: each line starts with the keyword “SET”, then space, then parameter code, “=” si n,
value of the parameter. Like this:
SET IPV4=192.168.1.20 sets local MBET-3 IP-address to 192.168.1.20
After parameter value there should not be any additional characters (like CR, LF, etc.),
the strin should be send to the MBET-3 directly. MBET-3 responds to every command with
either success or error.
The direct pro rammable parameters are these:

The command and parameters are upper or lower case, with no preceding or trailing characters like
space, CR, LF, etc.
The steps of initial programming are the following:
- Power-up MBET-3 and connect it to the PC/laptop’s serial port
- Set all basic network parameters (if DHCP is OFF)
- IP-address /IPV4
- Gateway address. /GATE
- Network mask. /MASK
- If there is MAC-conflict, set new MAC-address. /MACA
- Remote readin network number. This settin is essential as this is the only
way the server can identify the network to read. /NETN
- COM port settin s for remote readin network (baud rate and parity) – only if
different from defaults. /COM2
- Network messa e timeout – if there is no response from the network after
MBET-3 has issued command, MBET-3 responds to the server with timeout
error. /NETO
- Set IP-addresses of control and data operators. At least one control operator
IP-address must be set in order to ain remote control of the network. All
operator IP-addresses can be set remotely by control operator. /IPMA, IPCO,
IPO1-IPO4. If yo want access from anywhere - set 0.0.0.0 (defa lt for
Control Operator and Data OP1)
- other parameters
- Current date and time set. These are lost at power interruption. /DATE, TIME
- Time between two connections, in hours (1-48, default 1h). / PITO
- Due date set. At due-date MBET-3 connects only to the data operators. Set
day, hour, minute. /DUED
- Set max. number or connection retries and the time between two retries.
/RETN, RETI
- Server inactivity timeout. MBET-3 drops connection after expiration of this
timeout without server activity. /INTO
The parameters can be repro rammed remotely by control operator. Allowed
mediums for all the four data operators can be pro rammed only remotely by control
operator. All mediums are allowed for all data operators by default.
Current settin s can be checked locally by issuin command “GET”, space,
parameter code. Parameter codes are: MAIN, SERV, CONN, MEDx (x=1-4).
- GET MAIN – returns current firmware version, current date & time, MBET-3’s ID-
number, network number, workin time after power-up or power interruption in
days
- GET SERV – returns current firmware version, all operators IP-addresses,
predefined server connection time and the time remainin to the next connection
attempt
