HI,
how do i let a plc acquire data from a continuosly varying voltage and current source such as the from the contacts of a CCB IN A SUBSATION.
1.do i need a transducer, my guess is yes. If so what kind of transducer do i need for this kind of application.
2.the transducer is likely to bring in analog information
now if my plc has A/D module do i need to write say a ladder program for example for the PLC to recognise that an analog signal is coming in and that it needs to do the conversion to digital
hope u guys got some ideas
any help will be appreciated
