4.6 Real-time information (distributed clock)
0x2580 - ECAT DC: Real-time information
All time information provided in this object is based on UTC and transmitted in the format defined by EtherCAT for
this purpose: In nanoseconds, at a width of 64 bits, based on a date of January 01, 2000, (2000-01-01) and a time of
00:00.
There are various ways for the i700 servo inverter to receive its real-time information from the outside:
• From the (EtherCAT) master (DC synchronous in the EtherCAT state "Safe-Operational" or "Operational").
• By writing to subindex 4 (ECAT DC: Current time).

Subindex 1: ECAT DC: Status real-time information
Selection list (read only) Info
0 No real-time information received yet The i700 servo inverter has not yet received any real-time
information from the outside since switch-on.
• The i700 servo inverter is still operating with a time
which is based on the time when the device was
switched off last or which is based on the time stamp
of the firmware (whichever time is later).
1 Receive at least one piece of real-time
information
The i700 servo inverter has at least once received one
piece of real-time information from the outside since
switch-on.
• The first and the last time the i700 servo inverter has
received real-time information are displayed in
subindices 2 and 3.
2 Synchronous - cyclically updated The i700 servo inverter receives cyclically updated real-
time information from the outside.
• The i700 servo inverter reports this status if it is e.g.
DC synchronous in the EtherCAT state "Safe-
Operational" or "Operational".

Subindex 2: ECAT DC: Time stamp first real-time information
Display of the time when the i700 servo inverter received its first real-time information from the outside since
switch-on.
• In the "No real-time information received yet" status, a value of "0" is displayed.
