IoDrvEtherCAT.DCClockReferenceTime (PROP)¶

PROPERTY DCClockReferenceTime : LWORD

Returns the clock reference time in nanoseconds. Depending of the EtherCAT chip in the slave it is either a 32Bit value holding (overrun after 4.2seconds) or a 64Bit value. The clock reference is normally the first slave with DC enabled if DCSyncToMaster is not set to true. The reference time is read every bus cycle and the PLC synchronizes to this time.
