values
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
TRUE or
FALSE
_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
TRUE or
FALSE
_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
TRUE or
FALSE
_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.
Array [1..512]
OF BOOL
TRUE or
FALSE
_EC_DisconnSlavTbl
Disconnected 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 was disconnected.
Array [1..512]
OF BOOL
TRUE or
FALSE
_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
TRUE or
FALSE
_EC_PDActive
Process Data Com-
munications Status
TRUE when process data communica-
tions are performed with all slaves*.
*Disabled slaves are not included.
BOOL
TRUE or
FALSE
_EC_PktMonStop
Packet Monitoring
Stopped
TRUE when packet monitoring is stop-
ped.
BOOL
TRUE or
FALSE
_EC_LinkStatus
Link Status
TRUE if the communications controller
link status is Link ON.
BOOL
TRUE or
FALSE
