The data manager family of Endress+Hauser is growing: the most recent addition to the PC-Wetzer system prod- ucts forge is on its way to conquer the world of process automation.
To meet the strong demand from the market for a smart, compact DIN rail data manager for mounting in the control cabinet, about a year ago the starting shot for the RSG45 DIN rail development was initiated. A short “time to market”, compact design and the expansion of the display options of the integrated web server for optimal commissioning and operation were key objectives of the development. The posi- tive feedback from numerous field tests confirmed this: The expectations were fulfilled!
Full compatibility – multi-functional applications The RSG45 DIN rail is 100% hardware and software compatible to its counterparts with displays. It has the
same possibilities as the display devices. The I/O channels can be ordered freely configured with HART® or universal inputs. All interfaces and fieldbuses are also available. The RSG45 DIN rail offers an attractive entry price and product features, particularly in the acquisition of new clients by system builders, OEM customers and skid builders provides excellent conditions to significantly expand our market share. When used as a data and application manager, preferably for communication tasks, an on-site display is often not necessary. The installation is integrated in the control cabinet, allows easy wiring and the visualization and operation is carried out via the web server which has been considerably extended in terms of its functionality.
To that end, an application (e.g. plant visualization) can be accessed through a web browser window. A connection can also be estblished with cordless devices such as tablets. Ac- cess is possible, of course, via the Internet from anywhere in the world. With the already well-known application pack- ages such as mathematics, energy, waste water, etc. the device is suitable for many applications in most industries. Through the connection using the Ethernet-based fieldbus to automation systems (PLC, DCS, EcoSystems, etc.), the RSG45 DIN rail is predestined for use e.g. as an intelligent remote I/O with data preprocessing, application packages and control functions. This is a key differentiating feature in comparison to conventional remote I/Os.
Measurement data analysis: Turn your data into information
One of the outstanding strengths of the new RSG45 DIN rail are its wide range of communication capabilities. With integrated digital communication from the sensor level up to higher-level systems, ERP, cloud, etc. the device offers almost unlimited possibilities for communication. Particu- larly interesting is the possibility of building up a second communication channel, which is increasingly required in automation. In addition to the transmission of measured data in real-time via fieldbus to the automation system, Ethernet (TCP/IP, Modbus TCP/IP, OPC, etc.) is available for the transmission of large volumes of data as well as diagnostic and analysis functions in the control level or the cloud databases.
Many sensors, e.g. Endress+Hauser flowmeters not only provide the actual measured value, such as flow rate, but also temperature values, density, condensate, etc. using the HART® protocol. Here, the RSG45 DIN rail is in its element. As an intelligent HART® gateway it can preprocess values, perform calculations and link them together. The measured data or results are then transferred via fieldbus or Ethernet. Device connectivity and the provision of data and informa- tion for further processing are the basis for future industry
- solutions and cloud-based data management.
Intelligent sensor monitoring: iTHERM TrustSens cali- bration monitoring
For the iTHERM TM37x TrustSens, the RSG45 offers the new functionality “TrustSens calibration monitoring”. In an application with TrustSens temperature sensors connected via HART® the RSG45 monitors the sensors for self-calibra- tion. As soon as a TrustSens reports a completed calibration by changing the calibration counter, the RSG45 retrieves all relevant data from the sensor, provides the data with a time stamp and stores them in a database as a tamper proof calibration protocol to FDA 21 CFR Part 11. Directly on the device, via web server or via the Field Data Manager (FDM) software calibration certificates can be generated from the data records. Deviations from the reference temperature sensor are therefore continuously logged. The customer gains 100% transparency about his process and reduces the risk of unacceptable deviations in the temperature mea- surement to a minimum.
Simple ordering process across all device variants.The Memograph M DIN rail is the new basic device in the order structure of the RSG45. The display with the naviga-tor as well as the stainless steel touch display are available as an option with an additional charge. Customers who al-ready use the RSG45 with one of the two available displays will not be required to change their order structures. Due to the integration into the existing structure, therefore, no adjustments of the validation and approval processes are required, e.g. in the Food & Beverage and LSI industry .
With the new Memograph M RSG45 DIN rail Endress+Hauser rounds off the system components product portfolio. Data management at a top level, a wide range of application packages and software functionalities are, in addition to the outstanding communication properties, the guarantee for a successful market launch.
