Page 36: Introduction To Profinet
1 PROFINET IO Technology Introduction to PROFINET As a common solution for the industrial communication, the PROFIBUS and PROFINET International organisation introduced the PROFINET Industrial Ethernet standard. PROFINET is the innovative and open standard for Industrial Ethernet. PROFINET satisfies all require- ments for automation technology.
Page 37: Profinet Distributed Io
1 PROFINET IO Technology PROFINET Distributed IO The focus of PROFINET IO is to have cyclic data exchange between a controller and multiple often simple communication devices. The aim is to have high performance and ease to use. The PROFINET IO distinguishes the following different device roles. Please note a single device can have multiple roles.
Page 38 1 PROFINET IO Technology  IO Controller A PROFINET IO Controller is the central device in the PROFINET network. It has the control over the state of the network and processes the data and alarms. The IO Controller typically is a PLC Unit that processes the data and alarms in the user program.
Page 39 1 PROFINET IO Technology Number Description Communication Unit IO Module Submodule Channel Provider/Consumer Model The data exchange between IO Controller and the IO Devices is carried out based on the provider-con- sumer model. The provider sends its data to the consumer without a request from the other device. The consumer processes the data.
Page 40: Profinet Communication Services
1 PROFINET IO Technology PROFINET communication Services The IO Controller establishes a connection to its IO Devices based on the configuration which has been given by the user. The Application Relation (AR) includes all data needed to achieve this data exchange.
