XFC | eXtreme Fast Control Technology

XFC performance data

Extreme short control cycle time

  • 100 μs (min. 50 μs)
  • new performance class for PLC application: control loops with 100 μs

Extreme fast I/O response time

  • from 85 μs
  • Deterministic synchronised input and output signal conversion leads to low process timing jitter.
  • Process timing jitter is independent of communication and CPU jitter.

Signal oversampling

  • multiple signal conversion in one control cycle
  • hard time synchronisation through distributed clocks
  • for digital input/output signals
  • for analog input/output signals
  • support of analog I/O EtherCAT Terminals
    • up to 100 kHz signal conversion
    • down to 10 μs time resolution
  • support of digital I/O EtherCAT Terminals
    • up to 1 MHz
    • up to 1 μs time resolution
  • application
    • fast signal monitoring
    • fast function generator output
    • signal sampling independent of cycle time
    • fast loop control

Signal technology for terminals with timestamping (64 bit time resolution)

  • extremely precise time measurement for digital single shot events per cycle: resolution 1 ns, internal sampling 10 ns, accuracy with distributed clocks << 1 µs (+ input delay)
  • exact time measurement of rising or falling edges of distributed digital inputs
  • exact timing of distributed output signals, independent of control cycle
  • absolute distributed clocks time with 64 bit resolution, easy time handling over > 580 years

Signal technology for terminals with multi-timestamping (32 bit time resolution)

  • precise time measurement of up to 32 events per cycle: resolution 1 ns, internal sampling 10…40 µs dependent on configuration
  • exact time measurement of rising or falling edges of distributed digital inputs
  • exact timing of distributed output signals, independent of control cycle
  • distributed clocks time with 32 bit resolution, sufficient for actions in a ±4-second time frame

Distributed-Clocks

  • distributed absolute system synchronisation for CPU, I/O and drive devices
  • internal sampling: 10 ns
  • distributed clock precision: << 1 µs
