What are ASI + & ASI - ? Are these the communication supplies of PROFIBUS ?
Are these DC voltages supplies ?
What is ASI DP Controller ? which has 5 connectors on it ...... 0v , 24 V , ASI + , ASI - & PE ... the profibus connector is connected to it (there are 2 violet cables connected to this profibus connector)
0 V & 24 V are supply voltages DC 24 V ......... ASI + & ASI - are 30vdc - 32 vdc voltages .....
the ASI + & ASI - supplies are coming from power supply (ASI)
this controller has red seven segment LED display ..... when there's problem in communication (i.e. some loosing in profibus connector) then " bf " fault is indicated on that controller in led display ....
thanks a lot
