Coil
The Coil is an output instruction used to represent a field device or internal memory
location that needs to be controlled. Use a normal coil when your application requires the
referenced address to equal ON (1) when the coil has power flow.
When the network logic passed power to the coil, the coil turns on and the address
equals 1. When the network does not pass power to the coil, the coil remains OFF (0)
and the address equals 0.

Coil Not
The NOT coil is used similarly like the normal coil, but if the referenced address equals
OFF (0), the coil has power flow.
When the network logic does not pass power to the NOT coil, the coil remains energized
and the reference address equals ON (1). When the network logic passes power flow to
the NOT coil, the coil is de-energized and the referenced address equals OFF (0).

Immediate Coil
The Immediate coil is used similarly like the normal coil, but the immediate I/O module
update is done when the coil is executed. The immediate coil is updated any time during
the controller scan and is not limited to the normal I/O update portion of the timeline.
NOTE: Both the image register and the I/O module are updated when the immediate coil
is executed.
