Note All of the system-defined variables for EtherCAT communications status show the current status.
A-110
Meaning
Shows the status of the Basic I/O Unit alarm
output (load short-circuit protection).
TRUE: Load short-circuit
FALSE: No load short-circuit
The corresponding variable is TRUE during
initialization of the CPU Bus Unit.
The corresponding variable changes to
FALSE when the initialization is completed.
The numbers in the variables indicate the unit
numbers of the applicable Units.
The corresponding variable is TRUE during
initialization of the Special I/O Unit.
The corresponding variable changes to
FALSE when the initialization is completed.
The numbers in the variables indicate the unit
numbers of the applicable Units.
The CPU Bus Unit is restarted when the cor-
responding variable changes to TRUE. (It is
changed to FALSE by the system after the
CPU Bus Unit is restarted.)
The numbers in the variables indicate the unit
numbers of the applicable Units.
If you change the Restart Flag to TRUE with
an instruction, the restart process begins from
refresh processing in the next task period.
The Special I/O Unit is restarted when the
corresponding variable changes to TRUE. (It
is changed to FALSE by the system after the
Special I/O Unit is restarted.)
The numbers in the variables indicate the unit
numbers of the applicable Units.
If you change the Restart Flag to TRUE with
an instruction, the restart process begins from
refresh processing in the next task period.
TRUE when the parameters of the specified
port are being changed. TRUE when the
Change Serial Communications Parameter
(SerialSetup) instruction is being executed.
FALSE after the parameters are changed.
It is also possible for the user to indicate a
change in serial port settings by turning ON
the corresponding flag through the execution
of an instruction or a user operation.
