Hello Martins; If I may make a suggestion before we look at an answer to your question: change the online translator you are using, the one you are using now is very inefficient; translations produced are nearly incomprehensible.. And it would help if you wrote the original question in correct Portugese so the translator can at least understand all the words you are using, Now, as far as I can make out in your question, you want to read values from a sensor that operates digitally at 230 VAC.You can select3 modules for the S7-300: -6ES7 321-1FH00-0AA0, SM231 DI 16 120/230 VAC -6ES7 321-1FF01-0AA0, SM321 DI 8 120/230 VAC -6ES7 321-1FF10-0AA0, SM321 DI 8-Isolated 120/230 VAC You will find the caracteristics and wiring schematics for each in this manual: S7-300 Automation System Module Data Hope this helps, Daniel Chartier |
