Hi All,

In our project we have S7-1500 controller IFM IO link master AL1102 which is connected to E & H Cerabar PM23 on IO link.

I want read Cyclic data of Cerabar PM23
Cerabr PM23. I have also attached IODD file.


 

To read Cyclic data I am writing below code



#sPressure_1 := PEEK_DWORD(area := 16#81, byteOffset := #iHW_Address, dbNumber := 0);

//Peek instruction is used access start 4 byte of Input data


#sPressure_2 := DWORD_TO_DINT(#sPressure_1);// #sPressure_1-->DWORD,

#sPressure_3 := SHL(IN := #sPressure_2, N := 2);  //#sPressure_2/3/4-->DINT

#sPressure_4 := SHR(IN := #sPressure_3, N := 2);//#sPressure_4-->DINT

#sPressure := DINT_TO_REAL(#sPressure_4);//#sPressure = Current Pressure



I don't have physical E & H devices with me for testing, Whether I have written correct code to access cyclic data.

Please suggest.

Hi ,

Thanks for reply,

I am using IFM AL1102 as a IO link master.

Actually there are 2 IODD files available.

1.How to access 30 bit below data

2.Below Image for refrence. If Data is 32 bit then i will be to convert it from DWORD to Real
