2347What is the processor scan time of allen bradle control logix processor 5555 lenin lenin123us@rediff.com
1 10650hi friends,can u send me the link for downloading Allen_bradley_RsLogix_500_Pro_V_7.0 software with activation file.or how can i find activation file for this.
2 5326i have D.p. transmitter of range 0 to 2540 mmWC, i want to use this for flow measurement (0 to 500 ltr/hr.) what should i do?
9 25109when i installed Allen_bradley_RsLogix_500_Pro_V_7.0,after installation it gives the fatal error.it need activation file.from where and how i can find its activation file.

How to calibrate the flow transmitter
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.
