The TH Link is a monitoring tool that sits on the PROFIBUS network and ethernet and can alert you not only when there is a problem but potentially before the problem occurs as it looks at patterns in the error messages and spots trends.
It has its own webserver built in for independent use and access but can also be connected up to a Server with TH Scope running to add additional features and gather data from multiple TH Links PB or PN.
This link gives you access to a demo network running in Softing’s HQ in Munich, where you can investigate issues that have happened on their demo network over the last month or so. If you click on Link-PROFIBUS-1 on the left hand side and then click Diagnostic list you can see in there all the issues that have been recorded.
For instance ID 8 in the list I saying that the device with address 9 has a System fault with the module 1. The wire in the first port of the first module is broken (or has no connection). This significantly reduces the amount of time taken to identify why production has stopped. I have included a screenshot from the interface in case they reset it (which they do from time to time).
