Hello Valdo; Participants in the Siemens forum come from many countries, and many do not understand Portuguese. To make understanding easier between members we have chosen English as an international interchange language. Please try to write to us in English on your next visit. How fast must your digital output generate the pulses? Until a few ywears ago, there was a FM Stepdrive (FM 353) that you could have integrated in your S7-300 configuration to pulse out signals to simulate a stepper motor in your project, if you knew the number of puldses to send to your other (undescribed) device. Unfortunately it has been discontinued , about 5 years ago, and there is no replacement. if the pulsing speed of a regular DO on your rack is sufficient for this operation, you might want to look at FB43, Pulsegen, that is used with FB 41/FB 42 PID controllers. I have no experience with that function as a standalone application, we used in with FB 42, the panmeters of FB 42 were linked to FB 43 synchonization, this gave us a bit of trouble if I remember well. One option that mght interest you is the ET 200S 2-Pulse module, 6ES7138-4DD01-0AB0 that can be connected to your CPU S7-300 over a Profibus link, using a IM 151-1 head module (6ES7151-1AA04-0AB0) on the ET 200S rack. See this manual for the ET 200S Technological Functions, including the 2-Pulse operating mode "Pulse Train": https://support.industry.siemens.com/cs/ca/en/view/45977588/21340171403 Hope this helps, Daniel Chartier |
