Hello Edmilson; Looking over your schema file, it seems that the designer of thoss network (I hope I am insulting no none, especially you!) does not understand the Y-link and its use. As you can see from the screenshot below and the following link, the Y-Link is designed as an interface between redundant controllers as Profibus masters (a S7-400H for exmple) connecting to one or more non-redundant Profibus-DP slaves. https://support.industry.siemens.com/cs/ww/en/view/43688632 Following a Y-Link you can have a number of non-redundant slaves and orther equipment, including repeaters (if you need to extend the length or number of slaves on the network). all of them will be connetd to either the primary or standby controller as Profibus master, depending on their status. Examining your network, the element named "Y" appears to be connected to slave nymber 16, i assume that "Y" is a Y-coupler, and that slave 16 should be a IM 153-2. But to create a Y-Link properly, you need 2 distinct IM 153-2, each connected to the Profibus interface of one of the 2 redundant Profibus masters. Your sketch shows slave 16 as a single unit, connected daisy-chain to the network, which is wrong. Your Y-Lik is not complete, therefore you will have error messages such as you are receiving. Study the following manual, there are sections on setting up and commissioning a Y-Link that should help you out: https://support.industry.siemens.com/cs/ww/en/view/1142696 At this time I do not think that your problem is related to the repeater and we can look at this later when you have clarified the presence of redundant controllers in your system, and the Y-Link connections to these controllers. One test you could do, if it is possible to modify your system temporarily, would be to connect one of your encoders directly on the main Profibus network, for example connecting encoder 17 to replace slave # 16 in the present network design. Modifying the network configuration in your Profibus master would then allow you to see if a connection t the encoders is possible directly wothout error. Hope this helps, Daniel Chartier |
