AC500 PROFINETCommunication Types

PROFINET provides different kinds of communication types

PROFINET NRT (non-real-time)e.g. process automation

TCP/IP, UDP/IP

PROFINET RT (real-time)e.g. factory automation

PROFINET IRT (isochronous real-time)e.g. motion control

www.infoPLC.net


PROFINET IO RT (Processed Fieldbus Ethernet)

PROFINET IO RT Features

Standardization organization IEC 61158

Nomenclature: Controller (Master) / Device (Slave)

Bus Topologies: Bus, Star, Tree

No direct Slave to Slave communication possible

Ethernet over PROFINET IO RT possible

Device description (GSDML) based on xml standard

Engineering tool to access the IO Devices temporally for commissioning

AC500 PROFINETPROFINET IO-Transfer Mechanism

PROFINET IO is not a typical master/slave communication

The process data are transmitted cyclically

IO Controller sets the communication basic cycle as the master (“SendClockFactor”)

Cycle time for data transfer can be preset for each IO Device due to optimize bus load

Cycle time is as set for each IO Device. Output data are sent by IO Controller, input data are sent by IO Device.

Acyclic communication is used for parametrizing, diagnosis, alarm messages

AC500 PROFINETPROFINET Standardization (1)

Each PROFINET IO Device has its own electronic data sheet, the General Station Description File (GSDML)

The GSDML files are usually supported by vendor (see also PROFIBUS user organization: http://www.profibus.com)

PROFINET defines 3 conformance classes: CC A, CC B, and CC C. AC500 PROFINET RT is certified to be conform to the class CC A

www.infoPLC.net


AC500 PROFINETPROFINET Standardization (2)

CC A

- Conduction-bound and wireless data transfer- Cyclic RT communication- Acyclic TCP/IP communication- Alarms/diagnosis- Definition of transfer cycle- Automatic address resolution- Identification & maintenance functionality- Basic mechanism for detection of adjacent devices- Prioritization of data transfer according to IEEE standard- Transfer media: 100 Base TX/FX

CC B

- Switches with MRP support (conform with IEEE 802)- Providing of data for device-to-device-communication- Application of SNMP- Comfortable device-replacement without usage of an engineering tool- Client-functionality with MRP redundancy

CC C

- Switches with IEEE802-conformity with bus-, phase- and real time clock synchronization

- IRT communication- TCP/IP/RT and IRT redundancy
