Hello, if the problem appears on the DP/DP Coupler, do you have also problems on other DP-Sales on the net? If the DP/DP Coupler is at the end of the Network check the termination and grounding of DP/DP Coupler and PROFIBUS cable. More information about grounding you will find here: SIMATIC NET PROFIBUS Network Manual System Manual Refer for that part Appendix C.6 regards Rated X |

If , one side of the pribus , you poweroff the last slave you get a bus fault but when this slaveis restarted then the fault on the bus coupler does not reset automatically , you have to pull the cables out and put them back and this is not a good solution |
