Hi, for a better diagnostic you can use the free diagnostic tool Amprolyzer. "The Amprolyzer V3.2 bus monitor (Advanced Multicard PROfibus AnaLYZER) is a powerful software for PROFIBUS network diagnostics. This tool is an important aid when checking PROFIBUS networks during commissioning and maintenance. Amprolyzer is also an important tool in the development of PROFIBUS products." I use this tool and I think it is one of the best tools. This tool you find there: http://support.automation.siemens.com/WW/view/en/18818699 Attention: You have to use a PG/DP adaptor. |

Hello DAYALAL BHUT, I've seen these drawings, even if left side of pages aren't visible good. You mean Profibus Address 86 (TB11; Thermosetter III), instead Addr. 84. I am remember to similar problem in automotive industry - transfer line. I had sporadically fallout of one DP slave. My problem was appear after small mechanical modification of one transporter. In the moment when transporter start to move with load, mentioned ET slave had communication fallout. After lot of time we had found source of problem. The mechanical company which was made some works, cut the power supply cable of SITOP to another device. Mentioned DP slave was connected to same DC circuit and short circuit make voltage drop. In the same moment the safety relay was tripped by mentioned voltage drop and disconnect this circuit. After reset all was OK - no fault. The short circuit time was too short (peak), therefore circuit breaker was not tripped. I suggest You try to supply the IM module only of problematic DP slave - ET with separate power supply (Sitop). Separate IM of existing power supply. Vitas Attachment20110404155515.pdf (148 Downloads) |

Hello Vitas, I will be providing seperate power supply only to problematic ET to rule out momentoriry dip in power. Also, I am checking for any possibility like cable cut or load etc. I again attach network diagram which is clear with connection. My previous scan was notindicating all node connection. As pointed out by you, the problem is at address 84 only. (I have wrongly mentioned address as 86) With warm regards, Bhut AttachmentDrawline Profibus Network_CP 11.pdf (132 Downloads) |

any 1-ET-200 connectionis creating problem. so disconnect ET-200 1 by 1 & check without load. |
