There won't be any current drop in mA, but when you consider
Voltage there will be Voltage drop.

-->main Reasons for Voltage drop

#Distance between the Field and Control Room(more the
Distance and more will be the Voltage drop)

#Consider if the Distance is small between the Field and
Control room,then also there will be Voltage drop,because it
is milli Volt

#Theory Sum of the incoming current and Out going current
is always Zero 20mA=20mA by KCL, if you find any thing
wrong,you can check it in Transmitter Outlet and the DCS
Inlet will have the same milli Amp.

Thank you

A PLC is programmed to drive three motors A, B and C as follows : After running motor A for an hour, motor B should get ON and motor A should get OFF. And after running motor B for an hour, motor C should get ON and motor B should get OFF. And after running motor C for an hour, motor A should get ON and motor C should get OFF. (That is, a cyclic repetition with time period one hour) Now, the second condition is: If any motor gone faulty and is tripped, the consecutive motor should get ON and the faulty (tripped) motor should be eliminated from cyclic repetition. The remaining two motors should bear the cyclic repetition of one hour each. (For healthy motor take logic as high and for tripped motor take logic as low) Now, the third condition is: When motor A load(Amps) exceeds 60% of its rated load, motor B should get ON in parallel to motor A. And when both motors A & B are running in parallel, and if their load exceeds 60% of their rated load, motor C should also start in parallel to A & B. [Here the cyclic repetition is eliminated, until their loads become normal(40%)] [Take logic high(1) for load at 60% and logic low(0) for load at 40%] Now draw a flow chart or a ladder diagram to fulfill the above condition.
