  1. Thank you very much panic mode for the write up. my goal is I wish to control flow. For example if I need 100 liters i should input the requirement in my HMI and once 100 liters is dispense The pump should stop, Different amount of litters maybe requested depending on the need.  Now my flow meter has been set at 1 liters per pulse, pulse width is 100ms and scan cycle is 3-5ms that is the scope of the project thanks
  2. Thanks panic mode, I will restructure the program. but I need to use the count up. For accumulation and pre-set for my application.
  3. Panic mode. Okay thanks for the identification' please how do I rectify this ?
  4. please find attached the program UNTITLED_BAK001-pages-supprimées (2).pdf
  5. Panic mode thanks for your contribution. pulse width is 100  milliseconds I believe that's slow, secondly the reading from the flow meter aligns with the PLC HSC, but it's the CTU and HSC counts that does not align.
  6. Hello all thanks for the Verious contributions.  After going through the program detaily I realize that the flow meter actually counts the same with my PLC HSC. But now my HSC does not count the same with my count up  CTU. For example the HSC is counting on 5 and CTU on 3 Please is there any possibilities for the both to count the same ?
  7. Hello Sir, thanks for the reply  the HMI reads from the micrologix data table. Am using Delta DOP B series HMI
  8. Hello Sir, thanks for the reply. am using E+H promag 50 that's flow meter and Allen Bradley 1400. In builder HSC. thanks 
  9. Hi experts, the pulses counted in my flow meter are not the same with what is counted in my PLC. my flow meter is set at 1 liter per pulse, and the pulse width is 100 mili-seconds  my PLC filter is set at 5 micro-seconds. example for 12-13 seconds in my flow meter readings 23 liters will be dispense for the same 12-13 second it shows 12 liters dispensed on my HMI. please what settings are required to make both the PLC and flow meter count the same ? am using high speed counter for this application. Please i will appreciate any contribution to enable me solve this problem  thanks     
  10. Hi experts thank you people for the wonderful contributions you made. The program works well now 
  11. Hello, I noticed something, I configured the two counters in the same program but different ladders, the first counter and it register counters well. the second counter only the Accumulator counts the destination register does not count.  Please will appreciate any contribution to resolve this suituation  thanks 
  12. okay i have PM you the program just now 
  13. Hi b_carlton thanks for the contribution you have made, when i configured HSC:0.ACC, it was working very well and counting in the destination register L9:0, but when i configured the other HSC, for example, when i connected my square wave simulator input in IN 4 which reads HSC:1, I noticed only the HSC was accumulating, but the destination register was not counting.  i connected the pulse input back to IN0, that is HSC:0 Only the accumulator was reading and the register L9:0 was not reading any longer.  just  thought of something, could it be that the battery am using to power my square wave generator is low ? and as such the pulses it generate now are weaker to work with the PLC scantime ?    
  14. Hi, my HSC counts accumulated pulses but destination register does not count ! will appreciate any contribution to help resolve this issue  thanks  HSC Issues.pdf
  15. Thanks for the video it helps.  Base on the video explanation, i came out with the schematic attached below, please kindly go through it. and see if i did it the right way.  thanks wiring diagram for AB 1400 & square wave generator.pdf
