IRT in Standard PLC


Why?


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



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
