SFB 47 for counting pulses

[Callisto 0]

Hi guys, I have a incrementral encoder that that churns out 360 pulses per revolution. I would like to use the integrated function of the S7-300 CPU314C-2 DP to count the pulses I have set the operating mode to count once and i am using channel 3 for the signal of the encdoer. Here are the settings for the basic parameters Main count direction : up Gate function : cancel count Comparison value : 0 Hysteresis : 0 Input evaluation : Pulse /direction Comparison : none interrupt : none There was a job error which states i was on the wrong operating mode or had faulty parameters when i got the program running. Can anybody give advice about the parameters that i should set or the operating mode which i should be operating on? Cheers
