Commissioning
Code Function Implementation Application/evaluation
D Diagnostic information of the
EtherCAT Master which, while it is
represented at the slave for
linking, is actually determined by
the Master for the Slave
concerned and represented there.
This information cannot be
characterized as real-time,
because it
• is only rarely/never
changed, except when the
system starts up
• is itself determined
acyclically (e.g. EtherCAT
Status)
State
current Status (INIT..OP) of
the Slave. The Slave must
be in OP (=8) when
operating normally.
AdsAddr
The ADS address is useful
for communicating from the
PLC/task via ADS with the
EtherCAT Slave, e.g. for
reading/writing to the CoE.
The AMS-NetID of a slave
corresponds to the AMS-
NetID of the EtherCAT
Master; communication with
the individual Slave is
possible via the port (=
EtherCAT address).
Information variables for the
EtherCAT Master that are updated
acyclically. This means that it is
possible that in any particular cycle
they do not represent the latest
possible status. It is therefore
possible to read such variables
through ADS.
Attention
Diagnostic information
It is strongly recommended that the diagnostic information made available is evaluated so
that the application can react accordingly.
CoE Parameter Directory
The CoE parameter directory (CanOpen-over-EtherCAT) is used to manage the set values for the slave
concerned. Changes may, in some circumstances, have to be made here when commissioning a relatively
complex EtherCAT Slave. It can be accessed through the TwinCAT System Manager, see Fig. “EL3102,
CoE directory”:
