Function
This table indicates the slaves that are regis-
tered in the network configuration information.
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 con-
nected 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 corre-
sponding slave has entered the network.
This table indicates the slaves that can per-
form message communications. Slaves are
given in the table in the order of slave node
addresses.
The element for a slave is TRUE if message
communications are enabled for it (pre-opera-
tional, safe-operation, or operational state).
Note Use this variable to confirm that mes-
sage communications are possible for
the relevant slave before you execute
message communications with an Eth-
erCAT slave.
This table indicates the slaves that are per-
forming process data communications. Slaves
are given in the table in the order of slave
node addresses.
The element for a slave is TRUE if process
data of the corresponding slave is enabled
(operational) for both slave inputs and out-
puts.
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 corre-
sponding 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 corre-
sponding slave is disabled.
TRUE when process data communications
are performed with all slaves*.
*Disabled slaves are not included.
TRUE when packet monitoring is stopped.
TRUE if the communications controller link
status is Link ON.
Shows whether a packet data file is being
saved.
TRUE: Packet data file being saved.
FALSE: Packet data file not being saved.
