Function
RSTA(531) turns OFF the specified number of consecutive bits.
SETB(532) turns ON the specified bit in the specified
word when the execution condition is ON.
Unlike the SET instruction, SETB(532) can be used to
set a bit in a DM or EM word.
RSTB(533) turns OFF the specified bit in the specified
word when the execution condition is ON.
Unlike the RSET instruction, RSTB(533) can be used to
reset a bit in a DM or EM word.
OUTB(534) outputs the result (execution condition) of
the logical processing to the specified bit.
Unlike the OUT instruction, OUTB(534) can be used to
control a bit in a DM or EM word.
Function
Indicates the end of a program.
END(001) completes the execution of a program for
that cycle. No instructions written after END(001)
will be executed. Execution proceeds to the
program with the next task number. When the
program being executed has the highest task
number in the program, END(001) marks the end of
the overall main program.
