Distributed data acquisition and control in real
The MSX-Box is an open Programmable Automation Controller
system (PAC). It has been specially developed for industrial measurement,
control and automation applications in real time where processes
have to be carried out within a defined time.

the production and IT level
The MSX-Box acquires sensor and machine data, processes them,
and controls or regulates the corresponding terminals.
can be integrated into a higher-level control system via Ethernet
or Profibus. By integrating the MSX-Box into the
company network via Ethernet, data can be forwarded to software
on the IT level for use in statistics or process optimisation.
Integrated into the field level
Measurement and control systems that monitor entire processes and
interact with machines or hardware must be capable of working with
data of different origins.
Field buses and signals
With the MSX-Box, you can acquire signals from different
field buses: CAN, Profibus, Ethernet, or signals from serial lines
such as ultrasound
sensors or scales.
The PAC system can also process the following signals:
• Digital I/O
• Counter: incremental, SSI, etc.
• Analog I/O
• Serial interfaces
• Motion control
Good for retrofits, too
The MSX-Box is suitable both for setting up a new automation
project and for optimising existing installations. That means
to benefit from your familiar hardware, while still equipping
your installation with the latest technology for more efficiency
In a steel plant, the MSX-Box is used to measure the thickness
of sheets. Laser sensors (±10 V) are used to measure the
sheet thickness. Simultaneously with the thickness measurement,
counters are used to determine the position of the sheet and
the feed rate.
The deviation in sheet thickness is calculated in
real time. The result of the calculation is used to control the position
the rollers in the next process step and thus to produce sheets
of a uniform thickness.
This information is then provided to higher-level
control systems through a Profibus interface, e.g. for statistics,
or as specification values for downstream processes.
inspection of engines, different metrics are acquired based on different
signal types: speeds, temperatures, pressures,
gas values, etc. Using the integrated CAN interface, messages from
the CAN bus can also be recorded.
To obtain a meaningful measurement
result, all metrics must be acquired at defined points in time.
The value of
metrics is then measured
at time t.
To use the data for later evaluation, the MSX-Box
stores the measured values in a database.
