Guys,
Is a DCS alarm a Digital Input? For instance, if a PT reaches a High alarm level of 5 bar or say 18mA, is this set point then converted into a digital input to the system/graphics/HMIs where ever it is displayed or logged?
Also... if the DCS is receiving multiple pump status signals from the MCC via profibus, is each status/command (such as start, stop, running etc) its own input, or is the profibus signal itself one input? as it is only terminating into one card?? im a little confused by this. I would imagine it is multiple seperate signals that are merely sharing the same comms cable / technology to get to where they need to be.
Thankyou
Anthony
