thanks for that. Could you elaborate as to why the termination resistor need to be on both side please?

Hi Craig, Please have a look: WBT PROFIBUS Installation Guide - 2 Assembling PROFIBUS cables Wrote: Termination prevents reflections that can disturb the data communication. The higher the baudrate and the longer the cable, the more important termination becomes. Termination should be activated/placed at both ends of every bus segment. With PROFIBUS DP the termination is powered to provide an idle level when nobody is sending data. |

Hello, Please check the address of S7-200 in system block. (Is it address 3?) Best regards, Wizard |

Hello, When using MicroWin, you make sure you are now looking for Remote address 3. Best regards, Wizard |
