Setting P223, P224, P245, P246

Example:

Digital inputs and outputs

Outputs	OUTPUT parallel		HEDA
	P223		P245
O1	1	(Bit 1)35	1	(Bit 1)
O2	2	(Bit 2)	2	(Bit 2)
O3	4	(Bit 3)	4	(Bit 3)
O4	8	(Bit 4)	8	(Bit 4)
O5	16	(Bit 5)	16	(Bit 5)
O6	32	(Bit 6)	32	(Bit 6)
O7	64	(Bit 7)	64	(Bit 7)
O8	128	(Bit 8)	128	(Bit 8)
	P224		P246
O9	1	(Bit 1)	1	(Bit 1)
O10	2	(Bit 2)	2	(Bit 2)
O11	4	(Bit 3)	4	(Bit 3)
O12	8	(Bit 4)	8	(Bit 4)
O13	16	(Bit 5)	16	(Bit 5)
O14	32	(Bit 6)	32	(Bit 6)
O15	64	(Bit 7)	64	(Bit 7)
O16	128	(Bit 8)	128	(Bit 8)

Each output is assigned a valency. Calculate the total of the valencies of the required outputs and enter this in the relevant parameter.

O4 to O16 should be influenced by the OUTPUT WORD command; O1, O2 and O3 should be available via OUTPUT Ox=y.

8 (O4) + 16 (O5) +32 (O6) +64 (O7) +128 (O8) = 248

When P223 = 248 and P224 = 255 (total of all valencies), you will obtain this setting.

8.6.1.3 COMPAX virtual inputs

COMPAX provides 48 logic inputs. These are divided into:

♦inputs I1 ... I16 which are actuated via the physical inputs.

♦virtual inputs I17 ... I32 which are activated via a fieldbus (object CPX_STW).

♦virtual inputs I33 ... I48 which are activated via a COMPAX command (OUTPUT O33 ... OUTPUT O48, or abbreviated: OT O33 ... OT O48).

Access to COMPAX control functions

Access to COMPAX control functions (functions which are allocated to inputs I1...I16 by default) can be configured via parameters P221 and P222 (see structural diagram on the right).

The allocation of the bits in P221 and P222 respectively to the relevant inputs can be found in the parameter description)
