I am working on a project where I need to communicate between MM440 and S7 PLC via profibus.
I have established the communication and configured the MM440 in Hardware configuration with 4 PZD's ( Process Data's).
The P2051 ( PZD to CB) is configured in such a way thats the structure of 4 words are,
Code: Select all
1st word = Status word 2nd word = Actaul Frequecny 3rd word = Actual Current 4th Word = Output Voltage
For Example I am getting value 6048 in the 3rd word, but the actual current is 1.4 A.
Can anyone please help me to find a solution for converting the IEEE format into Real format. If possible please upload the program to convert the IEEE to Real.
