Usable data
This section describes the payload that can be transmitted as the result of a corresponding
request.
Virtual inputs (Input Byte 0 ... Input Byte 15)
The virtual inputs are defined by the communications partner and transferred to the PNOZ-
multi. Each input has a number, e.g. input bit 4 of input byte 1 has the number i12.
Input Byte
0
i7 i6 i5 i4 i3 i2 i1 i0
1 i15 i14 i13 i12 i11 i10 i9 i8
2 i23 i22 i21 i20 i19 i18 i17 i16
... ... ... ... ... ... ... ... ...
Mask (Mask Byte 0 ... Mask Byte 15)
The mask is used to determine which of the virtual inputs sent in a Byte are to be set. For
example, if only inputs i0 to i5 are to be set in Byte 8, 0x3F must be entered in the mask in
Byte 24
Send virtual inputs to the PNOZmulti [ 83] .
Watchdog
The watchdog is used to monitor the virtual inputs.
If no virtual inputs are sent by a communications partner within a defined watchdog time
(watchdog timeout), the PNOZmulti sets the virtual inputs to "0".
The configuration and functionality of the watchdog varies and so is described in the re-
spective requests.
Virtual outputs (Output Byte 0 ... Output Byte 15)
The virtual outputs are defined in the PNOZmulti Configurator. Each output that is used is
given a number there, e.g. o0, o5 .... The state of output o0 is stored in bit 0 of output byte
0; the state of output o5 is stored in bit 5 of output byte 0 etc.
Output Byte

o7 o6 o5 o4 o3 o2 o1 o0
1 o15 o14 o13 o12 o11 o10 o9 o8
2 o23 o22 o21 o20 o19 o18 o17 o16
