Coils

The Micro PLC instruction set includes the following coils:

±(	)±	Coil. The basic type of program output.
±(SET)±		Set coil. Used to set a specified reference to 1.
±(RST)±		Reset coil. Used to reset the same specified reference to 0.
±(MCR)±		Master Control Relay. Used to set a group of outputs to 0.
±(SKIP)±		Skip. Used to cause a group of outputs to hold last state.
±(END)±		End of MCR or Skip

Using Coil Pairs

The following types of coils must always be used in pairs. If one of these instructions is used in the program, the paired instruction must also exist somewhere in the program.

SET	RST	Set and Reset
MCR	END	Master Control Relay and End MCR
SKIP	END	Skip (rungs) to rung containing End

±(SET)±		(F2)	Set coil
±(RST)±		(F3)	Reset coil
±(MCR)±		(F4)	Master Control Relay
±(SKIP)±		(F5)	Skip
±(END)±		(F6)	End of MCR or Skip

The selected coil type appears at the end of the rung:

2.Enter an appropriate address. For a coil, enter an address in output (O) or internal coil (C) memory. For example, C0001. You don't need to enter leading zeros.
