Provider
External time providers are components that determine an external time offset in relation to the local system time through an external information source and make it available in TwinCAT. This allows external time consumers to receive a corrected time, independent of the provider.
TwinCAT also supplies providers with:
- NTP providers: an implementation that queries and provides a time signal from an NTP server via (S)NTP.
- DC providers: An implementation that passes on the DC time from the EtherCAT master to TwinCAT as an offset (e.g. via IEEE1588 or PTP)
- In addition, the customer is able to provide his own providers.
