Delphin - Model ProfiMessage D -Measuring Device for Modular and Flexible Data Acquisition

The device utilises faster processor technology to provide the resources needed to realise any application. Its modular design is based on the use of master and slave devices. These can be equipped with one or two I/O modules. A large number of I/O modules means systems can be adapted to different sensor types as well as to the number of channels required. The I/O modules are equipped with 8–24 analog or digital inputs and outputs. In addition to these modules, a range of fieldbus interfaces are also available. Easy connections are possible to PLC control systems for data exchange purposes. With such a diversity of features and functions offered by ProfiMessage D devices, you gain instant benefits:

• Cost savings – just one system for measuring, monitoring and automation
• Time savings – easy to configure and practical to use
• Compatible for future needs – with OPC UA, ready for the IoT

ProfiMessage D enables you to easily develop applications according to your requirements, whether for measuring processes at machines, systems or test stands.

Independent data recording

ProfiMessage D devices record measurement data independently to an internal data storage capability of up to 32 GB, large enough for several billion measurement values including precision time stamps. A USB interface is available to extend the data storage capability via a USB stick.

Measurement data can be instantly read out online via an Ethernet interface during runtime. This can be performed manually on request or automatically according to a set time schedule. For stand-alone, network-independent operation, recorded measurement data can be transferred at the press of a button to a USB device for offline analysis.

Integrated IoT compatibility

Connecting a ProfiMessage D device to the cloud is possible for a range of application scenarios. Online measurement data can be transferred to a PC connected to the internet. The PC can then be used to access both current and historical data and to portray such data in trends (online applications). If the ProfiMessage D device is used as a stand-alone device for recording measurement data, the data can be automatically and regularly transferred to a cloud drive (offline applications). The data can then be accessed from the cloud and evaluated offline using the ProfiSignal software.

In online applications, the DataService software, which creates the connection to the ProfiMessage D devices, is run on a server in the cloud. Connection of the ProfiMessage D devices to the cloud takes place wirelessly via LAN/WLAN – secured via VPN. The required services, such as user authentication from a ProfiMessage D device, is provided as standard.

The DataService saves the measurement data to a database on the cloud server, and provides both online and historical measurement data for ProfiSignal trend diagrams. To set up such a solution requires a cloud server to enable the running of the DataService. The cloud server can be a server on the internet, a server on a company network, or a standard local PC.

Offline applications require only cloud-based server storage resources. The ProfiMessage D is connected to the internet via LTE or LAN/ WLAN and transfers its off-line measurement data using FTP, CIFS or NFS. When required, transfer to the server can also be made via a VPN. Users can download files from the cloud server and evaluate data off-line using ProfiSignal.

Diverse fieldbus interfaces

The variety of ProfiMessage D interfaces makes it very easy to communicate with external systems. Regardless of whether data needs to be exchanged with a PLC, a frequency inverter or an intelligent field device, setting up the interfaces and data exchange is very easy to understand.

Flexibility for any sensor or actuator

Depending on the I/O module being used, each input can be individually configured for measuring mV, mA, RTDs and thermocouples. Universal inputs  for voltage, current and temperature measurement make ProfiMessage D devices extremely flexible. Digital inputs are also available as status or frequency inputs, as well as digital and analog outputs. 

A major advantage of ProfiMessage D devices is that the inputs and outputs are differential, high-precision and galvanically isolated – from each other and from the power supply. Earth loops are effectively suppressed. A unique system architecture also enables problem free measuring of non-isolated sensors.

ProfiMessage D master and slave devices can each be equipped with up to two I/O modules. A single master device can be connected with up to 20 slave devices of the same housing designs. Data exchange between master and slaves takes place via a real time expansion bus using robust dual-wire technology.

Slave devices can be decentrally located and managed from a single master device. Nine different I/O modules are available for ProfiMessage D devices. Each master or slave device can be equipped with two I/O modules. When a master device is intended to process fieldbus signals only, it can be supplied without an internal I/O module.

Test stands frequently need to acquire combined vibration and process measurement data from rotating machinery (e.g. pumps, drives, motors, compressors). Such tasks can be performed using ProfiMessage D devices in combination with time-synchronized Expert Vibro or Expert Transient devices. Such combinations enable extremely slow measurement values to be acquired, recorded and analysed, along with measurement values of up to 50kHz.

Diverse fieldbus interfaces

The range of ProfiMessage D interfaces makes it extremely easy to communicate with external systems. Setting up interfaces and exchanging data is simple whether for a PLC, frequency converter or intelligent field device.

The number of ProfiMessage D interfaces has been further extended compared to its predecessor model. In addition to PROFIBUS, a optional PROFINET interface is now available. There is also an option for WLAN.

LAN/TCP

The LAN interface transmits all measurement data at high speed across an intranet or the internet. Any networked PC can access a ProfiMessage D via this interface. Other TCP services such as NTP, SFTP, HTTP and SMTP are supported. Internally stored data can also be read out via the LAN.

OPC UA

All Expert devices can be optionally equipped with an OPC UA Client/Server interface. This equips the ProfiMessage D series devices for universal measurement-data exchange at field level and therefore meets Industry 4.0 requirements. Measurement data and threshold violations can be immediately transmitted to subsystems via OPC UA. The OPC UA interface also provides data exchange to PLC systems and connections to process management systems.

PROFINET (optinal)

ProfiMessage D supports different PROFINET topologies, e.g. ring, line and topologies, while adhering to the CC-B conformance class.

PROFIBUS

ProfiMessage D also has two separate PROFIBUS DP slave interfaces and is integrated into PROFIBUS via a GSD file. Any analog or digital signal can then be read or written to from PROFIBUS. There is the option to switch operating mode to redundant PROFIBUS (according to PNO 2.212 V1.2).

Modbus TCP/ RTU

The LAN and RS485 interface can exchange data via Modbus TCP/RTU. ProfiMessage D supports this operation as a Modbus master or slave.

RS232/RS485

These serial interfaces can function with individual and proprietary protocols. The protocols can be created either directly by the user or by Delphin. Applications include the control of climate chambers, laboratory devices, power measuring units and GPS reception.

CAN bus

The CAN bus interface can be programmed as required. Any identifier can then be read, scaled, processed and recorded.

USB interface (master/slave)

The USB interface (type C) can be used to read out the internally stored data to a USB data stick or connect a PC.

Expansion bus

The expansion bus enables up to 20 slave devices to be connected to the master device.

Monitoring and automation tasks are performed independently by the ProfiMessage D device using software channels.  

Software channels are predefined function modules that users set up, configure and process within the device by mouse clicking. For example, computations can be performed on measurement via calculation channels. Limit-value channels monitor measurement data and issue alarms and dispatch emails in the event of an alarm.

There is practically no limit to the number of available software channels. All functions are independently processed by the powerful internal processor and ensure fully secure operation of the ProfiMessage D device.
