Im Projekt mit WinV3 funktioniert die Verbindung und ich erhalte Daten. Mit dem Raspi hingegen tut es nicht. Ist aber alles gleich. Wieso?
Code:
PROGRAM PLC_PRG
VAR
getAttributeSingle : ENIP.Get_Attribute_Single; (* fb to get a single attribute from a cip class *)
datareal : ARRAY [0..11] OF REAL;
END_VAR
(* this instance call requests the host name (= name of the device in the network) from the WAGO_750_352_FC_ETHERNET device as soon as xExecute gets TRUE )
getAttributeSingle(
xExecute:= ,
itfEtherNetIPDevice:= Powermonitor_500, ( instance of the device (instance is found in the I/O Image of the device) )
eClass:= ENIP.CIPClass.AssemblyObject, ( cip class which contains the desired attribute )
dwInstance:= 101, ( value of 0 is class level, range from 1..x is instance level )
pData:= ADR(datareal), ( data buffer )
wAttribute:= 3, ( attribute no. 6 of the tcp/ip interface object is the Hostname (CIP Spec. Vol.2 Chapter 5-3.3.2.6)*)
xDone=> ,
xBusy=> ,
xError=> ,
eError=> ,);
(* this instance call requests the host name (= name of the device in the network) from the WAGO_750_352_FC_ETHERNET device as soon as xExecute gets TRUE )

Hi,
ich denke es fehlt einfach beim Aufruf:
udiDataSize:= SIZEOF(REAL) * 12
also so:
(* this instance call requests the host name (= name of the device in the network) from the WAGO_750_352_FC_ETHERNET device as soon as xExecute gets TRUE )
getAttributeSingle(
xExecute:= ,
itfEtherNetIPDevice:= Powermonitor_500, ( instance of the device (instance is found in the I/O Image of the device) )
eClass:= ENIP.CIPClass.AssemblyObject, ( cip class which contains the desired attribute )
dwInstance:= 101, ( value of 0 is class level, range from 1..x is instance level )
pData:= ADR(datareal), ( data buffer )
wAttribute:= 3, ( attribute no. 6 of the tcp/ip interface object is the Hostname (CIP Spec. Vol.2 Chapter 5-3.3.2.6)*)
udiDataSize:= SIZEOF(REAL) * 12, xDone=> ,
xBusy=> ,
xError=> ,
eError=> ,);

Vielen Dank. Hat geklappt! Komisch das es in WinV3 ohne "SIZEOF(REAL)*12" funktioniert...
Gibt es eine Möglichkeit mit Explicit Messaging Wert von einer anderen Steuerung aus dem Codesys zu lesen?
