I received an inquiry today for a shaped Profibus-DP protocol encoder, model QEH80M-00008.

This is a product launched by TR, but the selection information can no longer be found on the Internet, through the model number and can not understand the relevant parameters. Through Google query, finally found the relevant information. Product information: QEH80M*8192/4096 V001 PBS-DP 20H7/N .

That makes it easier to solve, and we have the parameters to make customized alternatives.

First of all, let's confirm its resolution: 4096*8192, aperture is 20mm, communication protocol is Profibus-DP. these parameters are enough, let's match an alternative.

The picture shows the prototype model and the picture on the right shows the replacement model. The difference is that there are some differences in appearance and size, and the application parameters are the same, which solves the problem of alternative applications.

In practical use, there are many such substitutions, regardless of appearance and shape, to meet production needs. As long as the technician is familiar with importing GSD files, it is very convenient to use.

This is an alternative made for today's customer and it's pretty much perfect. The only difference is that the exterior shape is not quite the same, but it's good enough for normal use.

I'm going to record a note here in the hope that it will help more people who need it.
