Optional Interfaces

1.3.3.1 Modbus Interface, Serial
A serial interface with the Modbus protocol
allows communication with external data ac-
quisition systems. The interface enables the
exchange and modification of measurement
and analyzer signals as well as the remote
activation of procedures.
The RS 485 interface is electrically isolated
from the unit's electronic components and
facilitates the construction of a network of
several analyzers.
Optionally, an RS 232 interface can also be
used (and is also electrically isolated from
the unit's electronic components; however,
it only allows communication between two
end devices.
All supported Modbus parameters are listed
in chapter 9.
1.3.3.2 Modbus Interface, Ethernet
The Ethernet Modbus interface offers the
same form of comunication with a data ac-
quisition system as does a serial interface.
The most obvious difference is the plug-and-
socket connection: the Ethernet interface
uses an RJ45 socket.
This interface is also electrically isolated from
the unit's electronic components and enab-
les the construction of a network of several
analyzers.
All supported Modbus parameters are listed
in chapter 9.

Note!
The Ethernet Modbus interface cannot be
combined with the serial Modbus interface
( 1.3.3.1).
