| Q4 - Modular software library for measuring and inspection systems |
Ever increasing levels of productivity,
flexibility, and quality are required in industry.
Swift adaption of production processes to new tasks
is essential. Measuring and inspection systems which are
integrated into the production line play a decisive role here.
They supply information on the characteristics of the
processed product or the status of the current
process directly and without delay. This means that
deviations from the required quality can be identified
in good time to enable the appropriate corrective action,
through to control of the machine and process parameters.
|
|
|
|
Measuring is only the initial step - automation of the
testing process and connection to higher-level communications
networks are necessary, too, in order to fully utilize
the potential for product optimization.
|
|
|
|
|
Q4 is the name for intelligent solutions for quality
assurance and production optimization. Q4 is a modular
software system which is suitable for various applications
in the area of production. Q4 utilizes highly effective
internet standards to monitor testing and inspection systems.
|
|
|
Q4 runs on inexpensive PC hardware and supports established standards:
ProfiBus, CAN-Bus, RS 232, TCP/IP,
HTML, XML, etc.
|
|
|
|
The combinability of the elements and modules provides the Q4 software
system with the necessary flexibility for adaption to
the customer's requirements.
|
|
|
|
Short introductory period
|
|
The modules and elements of Q4 are already in successful
use in numerous industrial applications and have proven highly
effective in day-to-day production operations.
|
|
Q4 is divided into four elements:
|
1. Operation,
2. Data processing,
3. Automation and
4. Communication.
|
The Q4 elements provide measuring and testing systems with
intelligence on a standard platform: the personal computer.
With Q4, the PC shows the operator the test results, evaluates
the measurement data, performs the automatic test process, and
communicates with higher level systems via internet or intranet.
Q4 is a flexible modular system. Each element of Q4 is comprised
of standardized modules which can be combined according to the
task concerned.
