Profibus IO support
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.
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.
