ADwin
Stationsadresse, Anzahl und Größe der Datenbereiche müssen die gle-
ichen sein wie bei der Projektierung des Profibus. Die Modullänge wird
bei der Projektierung auch in Worten angegeben: 1 Wort = 2 Byte.

Beispiel
#Include ADwinPro_All.INC
#Define module 5
#Define node 2
#Define info Data_1
#Define out_arr Data_2
#Define in_arr Data_3
Dim out_arr[76] As Long At DM_Local
Dim in_arr[76] As Long At DM_Local
Dim conf_arr[200] As Long At DM_Local
Dim info[10] As Long At DM_Local
Dim i As Long
Dim error As Long
Init:
Processdelay = 3000000
For i = 1 To 10
info[i] = 0
Next i
Rem initialize profibus interface: 38 input data areas of 2 byte
Rem and 76 output data bytes of 1 Byte
error = P2_Init_Profibus(module,node,38,2,76,1,conf_arr,info)
If (error <> 0) Then
Par_1 = error
Exit
EndIf
Event:
Rem set data in out_arr[] to be transferred
For i = 1 To 76
out_arr[i] = (out_arr[i] + i)
Next i
Rem send and read data (output areas: 76; input areas: 38)
error = P2_Run_Profibus(module,out_arr,76,in_arr,38,conf_arr)
error = error And
Par_2 = error
Rem here the received data in in_arr[] can be processed
