Hello eliko, what exactly you mean by length measuring; can you explain it in more detail? Applications which involve encoders for length measurement can be connected directly to the High Speed Counters (HSC) of the onboard CPU 224 (i don't think it's CPU 214). More details on HSC can be found here. S7-200 System Manual-> Chapter 6 -> High Speed Counter Instructions |

So... How do you determine the frequency of a pulse sequence and speeds? /tf/WW/en/Posts/22906 As you know the speed (multiply by time) will give the "length" Best regards, Hristo Mihalev |

hi marwanco62
Rebar on my case is moving 90 m/min end I'm not sure if this method which you said will work enough precisly. I thought earlier to do thisas you said, but I thought we need two sensors, the first one to slow down the speed and the second one to stop motor for cuting. Anyhow thanks on your efforts to help. Best wishes Eli |
