Reference
_EC_RegSlavTbl Registered Slave Ta-
ble 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. Array [1..512]
OF BOOL
*1
TRUE or
FALSE page 7-14
_EC_EntrySlavTbl Network Connected
Slave Table 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. Array [1..512]
OF BOOL
*1
TRUE or
FALSE page 7-15
_EC_MBXSlavTbl Message Communi-
cations Enabled
Slave Table 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.
Array [1..512]
OF BOOL
*1
TRUE or
FALSE page 7-15
_EC_PDSlavTbl Process Data Com-
municating Slave Ta-
ble 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.

corresponding slave was disconnected. Array [1..512]
OF BOOL
*1
TRUE or
FALSE page 7-16
_EC_DisableSlavTbl Disabled Slave Table 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. Array [1..512]
OF BOOL

FALSE page 7-16
_EC_PDActive Process Data Com-
munications Status TRUE when process data communica-
tions are performed with all slaves*.
