Integrating the measuring device in the system
8.1.1
General notes
The device has (optional) fieldbus interfaces for exporting process values. Measured values
and statuses can also be transmitted to the device via fieldbus. Note: Counters cannot be
transferred.
Depending on the bus system, alarms or faults occurring during data transmission are
displayed (e.g. status byte).
The process values are transferred in the same devices that are used for display at the
device.

menu.
The following functions are implemented:
• Data communication with PC software (analysis software, configuration software, OPC
server)
• Web server
The following connections are possible at the same time:
• 1x Port 8000 (configuration software, OPC server or analysis software)
• 1x Port 8002 (OPC server only)
• 4x Modbus slave TCP
• 5x Web server
Ports can be changed!
As soon as the maximum number of connections has been reached, new connection
attempts are blocked until an existing connection has been terminated.

Modbus RTU/TCP slave
The device can be connected to a Modbus system via RS485 or Ethernet interface. The
general settings for the Ethernet connection are made in the
