54 EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A
Communication between the gas analyzer and the computer
Communication via Ethernet
Communication between the gas analyzer and the computer is executed via
an Ethernet connection, either as a point-to-point connection or via a net-
work.
The Ethernet connection enables communication
• with the test and calibration software TCT-light,
• with the configuration software ECT,
• for transmission of the QAL3 data, if the option QAL3 monitoring has
been integrated in the gas analyzer,
• for reading the measured values and for calibrating and controlling the
gas analyzer via the Modbus TCP/IP protocol.
NOTE
Detailed information on "Modbus" can be found in the technical information
"EL3000 Modbus" and "EL3010-C – Modbus via TCP/IP".
Setting up the communication between the gas analyzer and the computer
Basically, the following steps are required to set up the communication be-
tween the gas analyzer and computer:
1 Check and set the TCP/IP parameters in the gas analyzer and the com-
puter.
2 Establish and test the Ethernet connection.
3 Start the communication between the gas analyzer and the computer.
Check the TCP/IP parameters in the gas analyzer and the computer
The TCP/IP parameters in the gas analyzer and the computer must be
checked and changed if necessary for operation of the configurator. In the
case of a point-to-point connection, the IP addresses in the gas analyzer and
the computer must be carefully matched.
Example: gas analyzer: 192.168.1.4, computer: 192.168.1.2
