Hello Mortier; You show pulses giving a positive pulse at around 8 V. This does not match with the positive signal levels for the FM 350-2, as shown in this manual (and extracted in the attachment). SIMATIC S7-300 FM 350-2 Counter Module If you are stuck with using this specific equipment you wopuld have to look for some type of signal conditionner or pull-up circuit that would give you a readable signal as seen from the FM 350-2. Hope this helps, Daniel Chartier |
