PMX data acquisition and control system - The new industry standard for measurement

The sharpest measurement technology from HBM, perfectly designed for use in modern production: PMX, the new data acquisition and signal conditioning system for use in production control and industrial test benches. Strong performance, precise, reliable and highly efficient.

PMX enables professional and precise acquisition of force, torque, vibration, pressure, strain, temperature, voltage, current, frequency, speed, angle of rotation, rotational direction and many other quantities. All channels are rated with 38,400 samples per second. With 16 measuring channels and 32 calculating channels, PMX as a whole is rated up to 400,000 values per second.

This is not all: thanks to the support of real-time communication via Industrial Ethernet, a modern browser based user-software and flexible plug-in cards; it makes PMX the ideal module for application in modern production plants. All of this at an unbeatable price.

This makes PMX the first choice in process control, press-fit monitoring, monitoring of machines, industrial test benches and end-of-line test stands.

Product Description: PMX Signal Conditioner

Deciding to use PMX means you are using the newest industry standard in measurement technology. Furthermore, the PMX data acquisition control system sets ground breaking standards for use in production and test stands.

High precision for optimum results in production

High accuracy when acquiring measurement data gives you considerable efficiency advantages in your production processes. With a sampling rate up to 38,4kHz, PMX offers the greatest precision for optimal quality assurance.

Moreover, PMX can already process the signal internally and transfer this in real-time to your automation system. PMX identifies transducers automatically thanks to the integrated TEDS system: this is dynamic plug and measurement technology for efficient production.

Real-time data acquisition via Industrial Ethernet

PMX supports current Industrial Ethernet technology: for example Profibus, ProfiNET, EtherCAT and Ethernet/IP (available within short). Therefore PMX integrates seamlessly into modern production plants and enables the measurement, calculation and automation of your data in real-time.

Scalability: PMX grows with your requirements

Thanks to flexible plug-in cards and the possibility to connect different PMX modules to each other, you can increase your number of channels. You can integrate up to 300 measurement channels and up to 600 mathematical calculation channels.

CODESYS V3 software platform

With the CODESYS V3 software platform, PMX is the right solution to many tasks in industrial automation such as factory automation, mobile automation or process automation.

CODESYS provides everything you need for programming, fieldbus and I/O configuration, visualization, motion control and other tasks. Even your own plug-ins! The CODESYS V3 software platform is based on the  IEC 61131-3 programming system. All IEC-61131-3 programming languages are supported.

Not only can PMX with CODESYS V3.5 automate your application, but at the same time it also facilitates real-time visualization and control. Optimal web visualization is created in CODESYS software and run on the PMX together with the application. The amplifier's Ethernet /IP interface allows visualization on all browser based instruments. Thanks to consistent and space-saving cabling, multiple connectors are no longer required.

PMX with its WGX001 basic device already includes a CODESYS Runtime license. CODESYS software V3.5 is available from the supplied PMX-CODESYS CD. The corresponding PMX package and a collection of useful sample programs for code generation, web visualization and integration of CANopen modules are also included. The CD is included in the scope of supply or available for free from HBM.

The modern interface merely requires a web browser-based display and control unit and enables fast access to production data for evaluation and use for servicing and maintenance. Ethernet technologies and Internet now also allow cost savings in remote maintenance.

    Measurement data analysis and quality assurance using catman

    catman is the professional tool for measurement engineers and supports parameterization within a few seconds using an extensible sensor database. The integrated TEDS editor enables TEDS data to be written to and read from sensors fitted with a TEDS chip.

    In addition, catman facilitates building up of individual user and visualization levels and offers comprehensive analysis options. Graphical parameterization of the start and end conditions for test and measurement tasks is easy. The measured data can be saved in different formats, for example BIN, RPCIII, MAT, ASCII or XLS for quality assurance and analysis at any time.

    PMX driver package

    When the test and measurement equipment is used in a complex system, PMX needs to be integrated into the overall system or machine concept. The PMX driver package allows integration into LabVIEWTM* or proprietary software using .NET API (C++, C#, VB.NET). These software tools are used throughout the world and enable convenient and efficient programming and maintenance of user-specific solutions.

    * LabVIEW is a brand of National Instruments.
