Set Immediate, Reset Immediate (N Bits)
When the Set Immediate and Reset Immediate
instructions are executed, the specified number of
physical output points (N) starting at the bit or OUT are
immediately set (turned on) or immediately reset (turned
off).
The range of points that can be set or reset is 1 to 128.
The “I” indicates an immediate reference; the new value
is written to both the physical output point and the
corresponding process-image register location when the
instruction is executed. This differs from the
non-immediate references, which write the new value to
the process-image register only.
Error conditions that set ENO = 0:
SM4.3 (run-time), 0006 (indirect address), 0091 (operand
out of range)
