Profibus IO support

Hi,

Gsd file of hach analyzer (SC-200 Profibus Networ card)contains 4 byte of Prfibus Data(i.e. 2words from Slave)

First 2 words contains ERROR-STATUS and another 2 words contains Primary sensor value in IEEE 745 floating format.

I have selected 2bytes to 1DWord configuration.

Please find attached configuration I have done.

From Dword how I convert Primary value to real .This conversion is correct?

Please help for hach analyzer process value decode to correct format in control builder for profibus communication.

Greetings,

For Measurement-1/2 or 3 you have to Customize Input and create 2 words for each Actual Values.

There is a Function Block called "Words_To_Real" is exist in standart library.

Via this function Block, you can obtain Real values, 2 different Word Registers.

Hope it helps you.
