Basics of communication with Industrial Ethernet

1.1

Terminology

Industrial Ethernet
The term "Industrial Ethernet" covers a series of expansions to the Ethernet standard IEEE
802.3 with which communication suitable for an industrial environment is implemented. The
main aims are as follows:
● Deterministic data transmission - guaranteed response times and data rates
● Safeguarding against component failure
● Plant-specific network topologies with a focus on linear, redundant network structures.
The components must meet the following requirements:
● Industrial equipment, for example, signaling contacts, secure cables and plug-in
connectors
● Capability of withstanding extreme environmental conditions, for example extreme
temperatures, vibration, dust, dampness, electromagnetic interference.
PROFINET
The term PROFINET refers to the standard for Industrial Ethernet (IEC 61158/61784) that is
drawn up and supported by the Profibus & Profinet International (PI).
PROFINET unites protocols and specifications with which Industrial Ethernet meets the
requirements of industrial automation technology.
These include, for example:
● Real-time conditions
● Environment strongly affected by EMI
● High transmission safety, reliability and availability requirements
PROFINET contrasts with the office environment whose emphasis is more on high data
throughput and an extensive network. Further differences between the two network types
can be found in the numbers and heterogeneity of the nodes and their intermeshing.
SIMATIC NET
SIMATIC NET stands for a variety of network components that are available for innovative,
consistent realization of automation solutions under the umbrella of "Totally Integrated
Automation". PROFINET is the protocol that is used most often by SIMATIC NET
components in the context of the Industrial Ethernet.
