2 Instruction Descriptions
2-64
NJ-series Instructions Reference Manual (W502)
The operation of some typical instructions is described below.
z Out
FALSE is output while the master control is reset.
z OutNot
FALSE is output while the master control is reset. Caution is required because this operation of the
OutNot instruction is different from when the output of the previous LD instruction is FALSE.
z Set and Reset
The previous value of the output is retained while the master control is reset.
BREAK instruction This instruction is not executed.
Function blocks that are executed
over more than one task period (i.e.,
instructions with Done, Busy, and
Error output variables)
The power flow from the left bus bar changes to FALSE. If the instruction
was operating before the master control reset, execution of the instruction
is continued until processing is completed. Busy, Done, and Error outputs
will be made, but FALSE will always be output if the next instruction is an
output instruction. If a variable is directly connected to Busy, Done, or
Error, the proper value for the instruction specifications will be assigned to
that variable. You can also get the value of Busy, Done, or Error in the
form instance_name.output_variable.
Other functions These are not executed.
Other function blocks The power flow from the left bus bar changes to FALSE.
