Description
Fifth
Indicates the beginning of the main
program.
Indicates the end of the main program.
Indicates the beginning of a subroutine.
Indicates the end of a subroutine.
Branches processing to the subroutine
specified by <subroutine name>.
Resumes execution, after an interruption,
from the step where program execution
was interrupted.
Resumes execution, after an interruption,
from the beginning of the program.
Executes <instruction set> repeatedly
until <variable> reaches <end value>.
Note that <variable>, which initially
contains <start value>, is incremented by
<incremental value> each time
<instruction set> is executed.
Indicates the instructions to be executed
repeatedly.
Ends the "for" loop.
Branches processing unconditionally to
the step labeled with <label name>.
Branches processing to the step labeled
with <label name> when the inverter trips.
Branches processing to the step labeled
with <label name> when the <condition>
is met.
Starts the structured if statement.
Indicates the beginning of instructions to
be executed when <condition> is met.
Indicates the instructions to be executed
when <condition> is met.
Indicates the beginning of instructions to
be executed when <condition> is not met.
Indicates the instructions to be executed
when <condition> is not met.
Ends the structured if statement.
Executes the instructions specified after
"case" when the value of <conditional
variable> is <conditional value>.
Indicates the conditional value and the
beginning of instructions to be executed.
Indicates the beginning of instructions to
be executed when the value of
<conditional variable> is not <conditional
value>.
Ends the select case syntax statement.
Executes <instruction set> repeatedly
until <condition> is met.
Indicates the instructions to be executed
while <condition> is not met.
Ends the "until" loop.
Waits for "***.**" seconds.
Waits until <condition> is met.
Executes <instruction set> while
<condition> is met.
Indicates the instructions to be executed
while <condition> is met.
Ends the "while" loop.
Increments the value of <variable> by 1.
Decrements the value of <variable> by 1.
