Optimized Control- and Communication- Architecture for highest - - PowerPoint PPT Presentation

Optimized Control- and Communication- Architecture for highest Performance TwinCAT The eXtreme Fast Real-time Control Software

• real-time with MS Windows -> cycle times up to 50µs
• standard IEC61131 programming in XFC real-time tasks
• standard features of Windows and TwinCAT are

XFC compliant

EtherCAT The eXtreme Fast Control Communication Technology

• 1000 distributed digital I/O‘s in 30µs
• EtherCAT direct down to the bus terminal, no sub-bus
• optimized usage of standard Ethernet NIC‘s,

i.e. Intel PC chips set architecture

• enhanced real-time features based on

Distributed Clocks:

• synchronization, time stamping, oversampling

Optimized Control- and Communication- Architecture for highest Performance

Bus Terminals The eXtreme Fast I/O Technology

• complete I/O product portfolio for all signals
• high speed digital and analog I/O’s
• time stamping and oversampling terminals for

highest time resolution up to 10ns
