!
Note!
The USB interface is always active and can be used independently of other interfaces. Parallel oper-
ation of multiple optional interfaces, e.g. fieldbus and Ethernet, is not possible.
4.5.1 Ethernet TCP/IP (optional)
The Ethernet interface is galvanically isolated (testing voltage: 500 V). A standard patch cable (e.g.
CAT5E) can be used to connect the Ethernet interface. A special cable gland is available for this pur-
pose which allows users to guide pre-terminated cables through the housing. Via the Ethernet inter-
face, the device can be connected using a hub or a switch or directly to office equipment.
• Standard: 10/100 Base-T/TX (IEEE 802.3)
• Socket: RJ-45
• Max. line length: 100 m

4.5.2 Modbus TCP (optional)
The Modbus TCP interface is used to connect the device to higher-order systems to transmit all
measured values and process values. The Modbus TCP interface is physically identical to the Eth-
ernet interface (→ ä 19). Connection → å 19.
