When the Output instruction is executed, the specified
n
parameter (n) is turned on.
In STL, the output instruction copies the top of the stack to the
specified parameter (n).

When the Output Immediate instruction is executed, the
n
specified physical output point (n) is turned on immediately.
I
In STL, the output immediate instruction copies the top of the
stack to the specified physical output point (n) immediately.
Operands:
The "I" indicates an immediate reference; the new value is
215 216
written to both the physical output 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.
When the Set and Reset instructions are executed, the
S_BIT
specified number of points (N) starting at the S_BIT are set
S
(turned on) or reset (turned off).

The range of points that can be set or reset is 1 to 255. When
S_BIT, N
using the Reset instruction, if the S_BIT is specified to be either
a T or C bit, then either the timer or counter bit is reset and the
