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

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 of 19.2kHz, 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: EtherCAT and Profinet, and further standards for example Profibus (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.

Browser based software

The browser based PMX software sets new standards in terms of performance capability and user interfaces:

• Easy and intuitive to use, for both users in production and administration.
• Comprehensive programme library, numerous available drivers and API interfaces for maximum expandability and transparency.
• The modern interface allows fast access to production data for evaluation and for service and maintenance.
• Flexible and assured service and maintenance.

Overview of modules

PMX is ready for your application. For each PMX you can have up to 5 plug-in cards for different measurement quantities and communication interfaces: You can easily integrate further PMX modules, for up to 300 measurement channels.

The current PMX modules available are:

PX460

Frequency measurement module for the operation of

• up to four torque flanges (T10, T12, T40) for torque or rotational speed measurement including two times shunt calibration (TMC protocol under preparation)
• or two measurement channels for simultaneous measurement, for rotational speed, angle of rotation and direction of rotation or reference signal recognition
• or two angular/incremental encoders each, SSI, PWM sensors, magnetic transducers or pulse counters
• or four measurement channels for frequency measurement up to 2 MHz

Including 1-Wire-TEDS (sensor identification)

PX401

Four-channel measurement module for analog input signals and active sensors (+/-10 V voltage, +/-20 mA current). Including sensor supply and 1-Wire-TEDS (sensor identification)

PX455

Four-channel measurement module for full and half bridges, force transducers and load cells (strain gauges, inductive sensors, LVDT, potentiometric sensors)

• Including 0-Wire-TEDS (sensor identification)
• In combination with SD01A Zener barriers, sensors can also be operated as intrinsically safe devices in potentially explosive atmospheres, measurement circuit type (Ex II (1) GD, [EEx ia]IIC).

PX878

Multi-I/O module with eight digital inputs, eight digital outputs, five analog outputs (+/-10 V voltage)

• I/O functions are freely adjustable
• Measurement channels or calculation channels can be output via the analog signals.

PX01PN

Real-time Ethernet module (ProfiNET device) for automation tasks via ProfiNET (RT and IRT protocol)

PX01EC

Real-time Ethernet module (EtherCAT slave) for automation tasks via EtherCAT (up to 9.6 kHz frame rate)

PMX software - flexible and easy to use

Standardized software interfaces ensure access to all device parameters for configuration, control and analysis. Completely new software and control technology, so far only known from smart phones and tablet PCs, has been used for the first time in test and measurement technology.

PMX WebServer - integrated in the device

The browser-based PMX software has set new standards in performance and usability. Complex and error-prone software installation belongs to the past.

Users and administrators benefit from easy, intuitive control. Three different user levels with corresponding user rights are available to ensure access to the PMX and the process. 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®EASY/AP

catman®EASY/AP 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®EASY/AP 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 free PMX driver package allows integration into LabVIEW^TM* 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.
