n
(1) Turns ON the bit position of (D), which corresponds to the binary value designated
by the lower n bits at (S).
(2) The value of n can be designated between 1 and 8.
(3) No processing is conducted if n=0, and there are no changes in device designated
at (D).
(4) Bit devices are treated as 1 bit, and word devices as 16 bits.
n
The range 2 bits from exceeds the range of the corresponding device or the value of n
is other than 0 to 8, sequence program error occurs.
Safety observation warnings (SM24) are turned ON and error code (SD32): 10, detail
code (SD33): 8015H are stored.
