Versions

ProfiMessage D - modularly expandable and perfect for complex measurement tasks

The ProfiMessage D impresses with its consistent modularity: each master or slave device can be equipped with up to two I/O modules, with a total of nine different modules to choose from. Master devices without an internal I/O module are also available for pure fieldbus applications. Up to 20 slave devices can be connected to a master device via a robust, real-time-capable extension bus using two-wire technology - distributed centrally or decentrally. This creates a highly flexible system that can be adapted precisely to the task at hand.

FAQ

The ProfiMessage D is a modular measuring, monitoring and automation system for industrial applications. It is used wherever precise measured value acquisition, monitoring and control are required, e.g. in production, test laboratories, energy systems, mechanical engineering or for long-term measurements.

The most important features include:

  • Modularity: Flexible combination of different I/O modules for individual measurement tasks
  • High measuring accuracy: Up to 24-bit resolution and fast sampling rates of up to 600 Hz depending on the module
  • Galvanic isolation: Minimizes susceptibility to interference and protects sensors and electronics
  • Wide range of interfaces: PROFIBUS, PROFINET, Ethernet, Modbus, CAN, OPC UA, USB etc.
  • Self-sufficient data recording: 32 GB internal memory for network-independent measurements

The ProfiMessage D supports a wide range of sensor and signal types via the various I/O modules: e.g. voltage, current, thermocouples, resistance thermometers (Pt100 / Pt1000), frequency/status inputs, digital I/Os. The galvanic isolation and the high resolution and measuring accuracy also make the system suitable for demanding measuring tasks. This covers both simple and high-precision measurement tasks.

Thanks to modern interfaces such as OPC UA (client/server), Modbus TCP/RTU, PROFINET or PROFIBUS, the system can be easily integrated into networked production environments and automation systems. The modular expandability also enables flexible adaptation to growing systems.

  • Master and slave devices can be equipped with up to two I/O modules
  • Up to 20 slaves can be connected to a master device via the extension bus
  • Modules can be added or replaced at any time

This allows the system to grow flexibly with increasing measuring points, new sensors or future requirements.

Commissioning is supported by intuitive configuration software. Important are:

  • Selection of suitable modules
  • Correct interface and network parameters
  • Parameterization of automation and limit value functions (software channels)

If required, Delphin provides support with advice and commissioning service.

Software channels as extended functions

Realise and execute monitoring and automation tasks easily 

Our measuring and testing devices have extended functions, which are summarized under the term software channels. The online measurement data is offset against the software channels and then used for visualization, storage or control.  

In this way, entire programme sequences can be configured very simply and intuitively with the regulation and control function. These then run autonomously without PC support. This is how you use your data logger effectively, also as a monitoring device or PLC replacement. 

The software channels enable functions such as limit value monitoring, integration or online calculation and are configured very easily. This means that even users who are not experts in programming can easily implement their own monitoring tasks or balancing independently in the unit.
