	8.6.1.2 Free assignment of inputs and outputs
Free assignment	You can make the permanently assigned standard inputs I1 to I6 available for
of inputs	assignment using parameter P221. Meaning:
	Input	Function without	Function with SHIFT	Valency
		SHIFT
	I1 (X8/1)	SHIFT	-	1	(Bit 1)33
	I2 (X8/2)	Manual+	Find machine zero (MZ)	2	(Bit 2)
	I3 (X8/3)	Hand–	Approach real zero (RZ)	4	(Bit 3)
	I4 (X8/4)	Quit	Teach real zero	8	(Bit 4)
	I5 (X8/5)	START	reserved	16	(Bit 5)
	I6 (X8/6)	STOP	Break (breaks off data	32	(Bit 6)
			record)

Setting P221

Example:

Free assignment of outputs

Each input is assigned a valency. Calculate the sum of the valencies of the required free inputs and enter this in parameter P221.

Hand+ and Hand- should be possible via the inputs; I1, I4, I5 and I6 should be freely available.

1 (I1) + 8 (I4) +16 (I5) +32 (I6) = 57

You will obtain this setting using P221 = 57.

Note that when I1 is freely assigned (SHIFT), you can no longer perform any "Functions with shift" via the inputs!

You can directly cancel all input functions (apart from Hand+ and Hand-) as commands using interfaces (RS232, bus system).

♦The status outputs O1 to O6 can be freely assigned using parameter P225.

♦Use P223 and P224 to assign the outputs of the OUTPUT WORD command of the bus systems (Interbus-S, Profibus, CAN – Bus, ...).

♦Use P245 and P246 to assign the outputs of the HEDA bus (COMPAX with IPM via the option A1).

♦Permanently assigned outputs of unit variants (COMPAX XX30, ...) cannot be masked.
