First field transmitter to junction box than junction box to barrier than barrier to DCS or PLC in put card. Controller is integrate part of PLC than controller decode the input value and give order final control element through output card

How can i solve the problem of ROSEMOUNT 5300 guided wave level transmitter of full range? For more clearfication , another guided wave level transmitter VEGA brand have the same problem and i solved it by drain the champer from water and make "false signal suppretion" from transmitter push buttons it's configuration to tell the transmitter to avoid any built-up signal ,,, so my question how can i avoid the problem that rosemount read full range while the champer empty or any other ????

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.
