Function
TRUE if the same node address is set for
more than one slave.
TRUE if there is an error in an initialization
command addressed to a slave.
TRUE if there is an error in the slave's appli-
cation status register.
TRUE when a message is sent to a slave that
does not support messages or when there is
an error in the format of the response to a
message that was sent to a slave.
TRUE if the master detects an emergency
message that was sent by a slave.
TRUE if the Input Data Invalid state continued
for the following period because the EtherCAT
master could not perform process data com-
munications normally when it was in the Oper-
ational state.
• When the task period is 10 ms or shorter:
100 ms
• When the task period is longer than 10 ms:
10 periods o the task
Slaves are given in the table in the order of
slave node addresses. The corresponding
slave element is TRUE if the master detected
an error for the slave.
TRUE if the CPU unit cannot establish com-
munications within the set communications
period at startup.
Note You can use this system-defined variable
only for NX-series CPU Units.
