Hello Thomas，I can't connect to S7 Interface if I have many Signals。
Hello，as you can see，I have an Arduino Mega 2560 and I want to do my own PLC，the PLC has 24 DI、24 DO、8 AI、8 AO signals，when I add all the signals into S7 Interface it can't connect to PLCSIM（I use nettoplcsim），but when I deactivate some signals it works well，if I want it works with all my signals what should I do？I have used the most new G4A，thank you！

Hi, the number of signals is not an issue, I have seen models with more than 1000 signals. Have you tried changing (reducing) the MaxPdu Lenth (e.g. to 40). Did you tried the AreaReadWriteMode (but I don't know if that works with nettoplcsim).
Thank you Thomas，I change it to 200 and it works，thank you very much。
