Hello atv127, Take a look at link bellow: http://support.automation.siemens.com/WW/view/en/42087579 Here you can download a library with two blocks to convert input and output 0..20mA to 4..20mA and4..20mA to 0..20mA. The library was created on TIA 10.5, but you can open on TIA V11 and the library will be converted automaticaly. |

Hi, From 0-20 to 4-20 mA, the convert function is: y=1.25*x-6912, where x is count from 0 to 27648 for input and if x<5529.6 (at 4mA) assume that the sensor current circuit broken. From above, you can make your progam accordingly. I have done with that. As for the FAQ link (https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=42087579&caller=view), I dont know why but when I use the attatch lib together with ModbusRTU communication (slave), the communication is malfunction (return wrong data)....may be FC1 is conflict with some system function... |
