  1. Thanks Gambit. The question was not well understood the first time.It's much clear now. I have added a reset to M0 to stop the endless looping of the counter.  Regards.
  2. Develop a program that will latch on an output Y0, 20 seconds after input X1 has been turned on. The timer will continue to cycle up to 20 seconds, and reset itself, until input X1 has been turned off. After the third time the timer has timed to 20 seconds, the output B will be unlatched.
  3. How would you solve this problem in ladder?

    Thanks. Yes the question needs some review as it seems not to be workable as it is.It is a college question as I tutor college kids when I'm free.I wanted to find a better way to tackle the question. Regards.  
  4. How would you solve this problem in ladder?

    Here is the code I've written so far.It does not work well enough though.The part on throwing the start switch twice if stop was used to stop the motor is the problem. motor_with_counter_on _stop.gx3
  5. How would you solve this problem in ladder?

    Honestly somebody asked me and I got confused writing the ladder.
  6. A motor will be controlled by two switches.The Go switch will start the motor and the Stop switch will stop it. If the Stop switch was used to stop the motor, the Go switch must be thrown twice to start the motor. When the motor is active a light should be turned on. The Stop switch will be wired as normally closed.
  7. Thanks guys. I think it'll be better to just transfer it to the 3G insted of the 5U since this is my first time doing it as a tech in the field .
  8. Hello, I need to transfer  programs from two old FX 1N controllers to either an FX 5U or an FX 3G. I understand the recommended replacement is the 3G but the new 5U is  a better choice as it has more features. What are some of the pros and cons of both in regard to such factors as compatibility of the programs ie. How much will I need to edit the program to fit the new controllers? Regards.  
  9. Thanks @kraykov .I'll take a look. @drforsythe We just wanted an alternative to the 4-20mA to act as a standby while we were restructuring the system. 
  10. Thanks @Gambit.I will take a look. Normally HS counters  count up or down to a specified value as the input changes until a preset value is attained or it is reset .I am trying to figure out how you can actually  monitor incoming frequency(which indicates the flow rate) in real time which I can then scale accordingly.
  11.   .Hello guys, What is an example of a  program will read  frequency/Pulse output from a flow meter to Gx-Works 3 using a high speed counter?(PLC is FX5U) Image is attached.
  12. Great.The last two ladder rungs that use the DEMUL function are for scaling purposes,right?
  13. Thanks so much.I've connected 2V to each of the analogue modules.Why is it not being detected  in the program when I start monitoring?
  14. Dear all, I am new to Mitsubishi PLCs and I wish to read  analogue input(0-10V)  on the FX5U-32MR/ES.The PLC is compact. Could you please provide me with the required ladder code for that.The SD registers for the two channels is SD6020 alogue 1 and SD6060 for analogue 2. Thanks.
