Variable name _EC_EntrySlavTbl
Meaning Network Connected Slave Table Global/local Global
Function 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 network.

*1. For the NX102 CPU Units, NX1P2 CPU Units, and NJ-series CPU Units, the data type is ARRAY [1..192] OF BOOL.
Variable name _EC_MBXSlavTbl
Meaning Message Communications Enabled Slave Table Global/local Global
Function 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 message communications are enabled for it (pre-operational, safe-operation,
or operational state).
Note Use this variable to confirm that message communications are possible for the relevant slave
before you execute message communications with an EtherCAT slave.

Variable name _EC_PDSlavTbl
Meaning Process Data Communicating Slave Table Global/local Global
Function This is a table that indicates the slaves that are performing 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 outputs.
Note Use this variable to confirm that the data for the relevant slave is valid before controlling an
EtherCAT slave.
