What is the purpose of this article?

This article explains one way to configure non-standard PROFINET station names


1. Overview

When integrating a Rheonics inline viscometer or inline density meter into a PROFINET network, assigning a valid station name is one of the first steps for establishing communication. The station name must comply with the IEC 61158-6-10 naming requirements. This article explains an approach if, for some reason, a non-standard name is required.

2. Using Non-Standard Station Names

If your setup requires a non-standard station name, check if your programming environment supports a station name converter feature, as Siemens TIA Portal does:


“The TIA Portal supports PROFINET device names that do not conform with the DNS name conventions. A "converted name" is generated from the non-conform PROFINET device name. This is the device name that is actually loaded to the device. The PROFINET device name is converted only when it does not conform to the IEC 61158-6-10 rules. The PROFINET device name and the converted name are displayed for the properties of the PN interface. You cannot change the converted name; it is generated automatically.”
(Siemens, TIA Portal Documentation) 


Using this feature allows users to keep their preferred non-standard names (e.g., names with uppercase letters or underscores) in the engineering environment for easy identification and documentation. Internally, however, the sensor sees and operates with the standard-compliant converted name.

3. PROFINET Station name on TIA Portal

After adding a Rheonics device in Device & Networks, you can set the device name. Figure 1 shows an SRV with a non-standard PROFINET station name: Tank4_SRV.


Tank4_SRV is a non-standard name as it has uppercase letters and an underscore.

On Properties > Ethernet Addresses (see Figure 2), enabling “Generate PROFINET device name automatically” uses the name set earlier as the station name.

The automatically converted name tank4xbsrv5554 is IEC 61158-6-10 compliant and can be configured on the SRV.



4. Configuring Station name on Rheonics Viscometers

For FW3 sensors, PROFINET station name cannot be modified by the user. Contact Rheonics Support and provide the desired station name.


A configuration file will then be provided, which can be uploaded to the SME using the RCP software.


For more information on using the RCP software, see Running the RCP Program and Updating sensor configuration.
