Auxiliary Relays

Description	Auxiliary relays marked M behave in exactly the same way as Q Discrete outputs
	(see Discrete (DISCR) Outputs, p. 98), but do not have an electrical output contact.
	They can be used as internal variables.
	There are 31, numbered from 1 to 9 and from A to Y except for letters I, M, O.
	All auxiliary relays can be used, in the program, indifferently either as a coil or
	contact. They can be used to latch a state to be used in the form of the associated
	contact.
