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... |
