Basic principles of PROFINET

PROFINET IRT is the family name of an industrial Ethernet based digital net­
work protocol used for real-time control (prioritized, scheduled, fix time latency)
and test automation of machinery and test stands.
A wide range of master controllers are available and linked to decentralized
units (DAQ with sensors and actuators like valves or drives). All of those mas­
ter controllers and companies behind address different applications and some­
times even different markets. The idea is finding an easy way to integrate
QuantumX into this powerful fieldbus in a way that system integrators or end
users are able to add some value coming along with HBMs QuantumX and
SomatXR data acquisition solution - flexible universal inputs, high accuracy,
distributable, etc.
In general the advantages of a fieldbus and also PROFINET are:
S Reduce cost in wiring and installation through decentralized devices and
thus short cable length
S Reducing long cable lengths transporting analog signals by acquiring and
digitalizing field data close to measurement spot and sensor and thus get­
ting the benefit of reducing noise and getting higher signal quality
S High resolution and accuracy of measured value (24 bit)
S One single cable transferring many signals in real-time instead of hundred
analog lines to a central processor
S Higher dependability due to self-tests
S Highly reliable data transmission is less error prone
S Quickly extendible
S Less faults (wrong wiring)
S Easy diagnostics
S Flexible topologies (star, line, link from field to corporate management level
and cloud)
