_EC_PktSaving
Saving Packet Data
File
Shows whether a packet data file is being
saved.
TRUE: Packet data file being saved.
FALSE: Packet data file not being saved.
BOOL
TRUE or
FALSE
_EC_InDataInvalid
Input Data Invalid
TRUE when process data communica-
tions established in the primary periodic
task are not normal and the input data is
not valid.
BOOL
TRUE or
FALSE
_EC_InData1Invalid
Input Data1 Invalid
TRUE when process data communica-
tions established in the primary periodic
task are not normal and the input data is
not valid.
Note
You can use this system-de-
fined variable only for NX-ser-
ies CPU Units.
BOOL
TRUE or
FALSE
_EC_InData2Invalid
Input Data2 Invalid
TRUE when process data communica-
tions established in the priority-5 periodic
task are not normal and the input data is
not valid.
Note
You can use this system-de-
fined variable only for NX-ser-
ies CPU Units.
Note
This variable is always TRUE
for the NX102 CPU Units and
NX1P2 CPU Units.
BOOL
TRUE or
FALSE
_EC_RingBreaking
(Ver.1.40)
Ring Disconnection
TRUE when all slaves in the ring topolo-
gy except for disabled slaves are con-
nected and if there is only one point of
disconnection in the communications ca-
bles in the ring topology.
BOOL
TRUE or
FALSE
_EC_RingBreakNo-
deAdr
(Ver.1.40)
Slave Node Address
Before Ring Discon-
nection
When the
_EC_RingBreaking
(Ring Dis-
connection) system-defined variable is
TRUE, the slave node address before
point of disconnection is stored.
When the
_EC_RingBreaking
(Ring Dis-
connection) system-defined variable is
FALSE, “0” is stored.
UINT
0 to maxi-
mum number
of node ad-
dresses
*1.
For the NX102 CPU Units, NX1P2 CPU Units, and NJ-series CPU Units, the data type is ARRAY [1..192] OF BOOL.
Note
All system-defined variables that are related to the status of EtherCAT communications give the current status.
