4. System design for fieldbus communication
The Liquiline device is an assembly of modules, which are connected to a backplane residing inside acasing. Up to 8 sensors can be connected to the measuring device. For using PROFIBUS, EtherNet/IP or
Modbus communication a “485” or an “ETH”-module must be present with appropriate licensing.
The 485 module has a RS485 port to connect it to a PROFIBUS DP or a Modbus RS485 Network. An
additional Ethernet port is used to connect the device to a TCP/IP network. The ETH module has only the
Ethernet port and no RS485 port. The Ethernet interface supports the following services:
Service/Protocol
ICMP
DHCP
HTTP
Modbus TCP
EtherNet/IP

Function“Ping”, used to check reachability of a device in a network
Network configuration, Setting of IP address by DHCP server
Access to the web server of the measuring device
Access to process and diagnostics data of the measuring device
Access to process and diagnostics data of the measuring device

TCP-Port
7
546
80
502
44818

At any time one of the following fieldbus protocols can be active:
•
•
•
•
•

PROFIBUS PA (RS485) / PROFIBUS DP
Modbus RS485 (RTU/ASCII)
Modbus TCP
EtherNet/IP
PROFINET

It is possible to switch the active fieldbus protocol by entering the appropriate activation code. The lastentered activation code defines the active fieldbus protocol.
For the Ethernet connection to the web server no activation code is needed.

4.1.

Power up

On power up, the device must initialize itself, which takes up to 2 minutes. During this period, the device
will not respond to any communication.
About 10 to 30 seconds after the measurement view appears on the display Liquiline is ready tocommunicate, no matter if there are errors present or not.

4.2.

Non-volatile memory

The device configuration parameters are saved into a flash memory. New data is written to this memory bya special flash handler. It takes approximately 5 seconds after the execution of the write command that thedata will be saved. Data consistency is always ensured.

7. Web server / Ethernet interface
The 485 / ETH module comes with an integrated Ethernet interface which can be used in addition to thefieldbus interface. The usage of the Ethernet interface does not reduce the performance of the fieldbus
communication.
Note:
On the other hand, the fieldbus communication may delay the web server operation.

7.1.

Hardware connection

7.1.1. Cables
For temporary connections to the web server for service tasks normal patch cables (CAT5 or better) areusually sufficient.
For the permanent connection and integration into an automation system we recommend the usage of
PROFINET Cable Type A.

7.1.2. Grounding and Shielding
Correct grounding and shielding must be ensured. This is required to guarantee electromagnetic
compatibility (EMC).
For Ethernet installations the guidelines for PROFINET should be considered while planning the
installation. These installation guidelines are available for free download at the following website:

8. Configuring the laptop for web browser access
The connection of a web browser to a Liquiline 4 wire device is only possible when the Liquiline has the
485 / ETH module installed.
To connect a laptop to the Liquiline, the IP settings of laptop and Liquiline must match. This comprises the
IP addresses and the web browser settings.

8.1. Configuring IP settings with ‘IP Configuration’ software ofEndress+Hauser InfoServe
If the user has no admin rights to change the IP settings of his laptop he can use the software ‘IP
Configuration’ of Endress+Hauser InfoServe. This software must be installed by the administrator.
Please start the software.

In normal operation the laptop receives automatically an IP address by a DHCP server. Please select‘Configure address manually’ to deactivate the DHCP client.
Configure the IP address of the laptop accordingly to the Liquiline. The IP address consists of four bytes. It
may be adapted to the customers IP network. In this case ask the local IT administrator for a free usable IP
address.

Endress+Hauser

14Liquiline web browser connection Guideline
The default address of Liquiline is 192.168.1.212
To read the current IP address of the Liquiline see the menu
Menu/Setup/General settings/Extended setup/Ethernet/Settings:

The laptop must be in the same subnet, meaning that the left three bytes must be identical, and the lastbyte must be different. E.g. in case of the default setting of Liquiline the laptop can be configured to192.168.1.1
