IRT in Standard PLC – Why?
Introduction
Motivation
 Uses the same network for process data and standard
Ethernet data (e.g. VoIP) without this affecting the process
data
 Under IRT process data is transferred with its own interval
Requirements
Technology
Performance
Diagnostics
Safety
Integration
Profiles
Wireless
 Machine and plant structure with numerous line-switched
subscribers and short refresh times
 IRT devices guarantee shorter throughput times (30%)
 PLC synchronous initiates drive functions (e.g. positioning)
for a number of motion controllers
 PLC as sync master provides deterministic cyclical
communication for PROFINET with IRT
