Hi, Experts. Need help to count the Product Per Minute to show on HMI as Line output or average/min, could you please help to make sample calculation program for S7 300 313 CPU , The maximum production rate is aprox 250 CPM. I tried with simple counting within time frame 1 min but it need wait 1 min to updating on time and not accurate. I am using Photo sensor to detect product at output conveyors, Unfortunately there is no HSC function in PLC ------------------------------------------------------------------------------------------ |

Hi , Thanks for your valuable feedback, as a maintenance guy I don't have much experience in PLC programming, However I have managed to build own a sample logic which is giving me good result: I used ADD in FC1 by incrementing +1 and this FC1 called in OB35 in cyclic interrupt set 20mS and in another FC2 I used counting logic and result transferred to DB ,, I would like to share if this can help someone or ignore it.
