I-7188E1-ML

Converter cooperates with maxi mum three thermal energy meter s Kamstrup
MULTICAL 66CDE lub Kamstrup MU LTICAL III, and assures conver sion of
monitored parameters (according to specification described b elow) to Modbus TCP
communication standard.

Communication with Meters is p erformed with use of MBus prot ocol, and it is
necessary to equip them with MBus protocol communication modules.
Devices I-7188E1-ML and MBus10 are supplied with 12-25 V DC. Maximum current
of both devices is 1A.
Converter communication is performed by loading appropriate configuration text files
to mini FTP server, built in the Converter.
It does not apply to Ethernet interface parameters. Those pa rameters should be
configured through Co nverter serial port RS232. Aft er Converter activation in
Ethernet network those parameters may be then remotely modified through TELNET
console.

Converter requires for operati on in Ethernet network setting of static configuration
parameters, i.e.:

a. IP: in form of xxx.xxx.xxx.xxx
b. SUBNET MASK: xxx.xxx.xxx.xxx
c. GATEWAY: xxx.xxx.xxx.xxx
d. MBus Meters addresses are defined as last two digits of meter serial number,
or up to 250.

Converter operates up to 16 concurrent Modbus TCP connections, i.e. at the same time
up to 16 remote Modbus TCP clients may query converter for data.
