. Communication
The instrument has the function of communication with the upper computer, which can
complete the functions of parameter setting, data acquisition and monitoring of the low computer.
With industrial control software, under Chinese WINDOWS, it can complete dynamic screen
display, instrument data setting, chart generation, saving record, report printing and other
functions. It can also acquire the data and curves in real time through the company's upper
computer management software, and record the historical data and curves. Historical data and
curves can also be exported to Excel for data processing.
This instrument provides users with two standard interfaces RS-485 and EtherNet for
communication with the upper computer.
★
RS-485 mode allows a upper computer to connect multiple recorders simultaneously. This
communication mode is suitable for users of the terminal computer to form a network with the
recorder, and to receive real-time data of the recorder and connect with various control systems.
★
EtherNet communication allows multiple instruments to connect with the upper computer,
and exchange data at 10M communication rate. It is suitable for large amounts of data
communication between terminals and instruments. In case the communication distance is more
than 300 m, it can be realized by optical fiber network. As long as the IP address is well selected
in the recorder system configuration and set up in the computer management software, the
Modbus
Tcp
can be carried out.
