Meaning
This table indicates the slaves that are
registered in the network configuration in-
formation.
Slaves are given in the table in the order
of slave node addresses.
The element for a slave is TRUE if the
corresponding slave is registered.
This table indicates which slaves are
connected to the network.
Slaves are given in the table in the order
of slave node addresses.
The element for a slave is TRUE if the
corresponding slave has entered the net-
work.
This table indicates the slaves that can
perform message communications.
Slaves are given in the table in the order
of slave node addresses.
The element for a slave is TRUE if mes-
sage communications are enabled for it
(pre-operational, safe-operation, or op-
erational state).
Note Use this variable to confirm
that message communications
are possible for the relevant
slave before you execute mes-
sage communications with an
EtherCAT slave.
This table indicates the slaves that are
performing process data communica-
tions. Slaves are given in the table in the
order of slave node addresses.
The element for a slave is TRUE if proc-
ess data of the corresponding slave is
enabled (operational) for both slave in-
puts and outputs.
Note Use this variable to confirm
that the data for the relevant
slave is valid before controlling
an EtherCAT slave.
Slaves are given in the table in the order
of slave node addresses.
The element for a slave is TRUE if the
corresponding slave was disconnected.
Slaves are given in the table in the order
of slave node addresses.
The element for a slave is TRUE if the
corresponding slave is disabled.
TRUE when process data communica-
tions are performed with all slaves*.
*Disabled slaves are not included.
TRUE when packet monitoring is stop-
ped.
TRUE if the communications controller
link status is Link ON.
