ACOPOS 6D bootup failure，can't connect to all Segments

For my project, we used ACOPOS 6D with 86 Segments, and the layout is shown in the figure below. The current issue is that when we set the master on either the 1st or 10th Segment, we are unable to communicate with all the Segments. Currently, our tests are not controlled by PLC, but are configured using PMTool.

Power supply configuration: Green represents a power supply with 6 Segments, blue represents a power supply with 5 Segments, and yellow represents a power supply with 7 Segments.

But if we reduce the number of Segments, it will work. We have tried setting the master to number 1, removing the right part of the Segments, and it was able to communicate. However, if we add one more segment, it will all fail., it will all fail.

We have tried setting the master to number 10, removing the upper part of Segment. This still enables communication. However, if we add one more segment, it will all fail., it will all fail.

It can be initially determined that the position of the master (the position where it is connected to the PMC) and the number of communications are related. We have learned that one PMC can control up to 200 Segments, but currently we have only connected less than 100 of them and it doesn’t work.We hope to receive guidance from ever yone.

Hi @Zherui_Sun ,
Welcome to B&R Community,
I pinged the project manager of ACOPOS 6D in the morning and this is his answer “as according to the specifications it should work”, but I think your issue required deep investigation so I recommend to report the issue to our Support in China.

Please update us when our Support will identify the cause of the problem.

Ciao

OK. If there are any new developments, I will respond here. I can confirm that there is no problem with the hardware.

I have also replaced the PMC controller, the segments and the cabling, but the situation remains the same.

HI @Zherui_Sun , have you solved your issue, can you update us?

Hi , the problem has not been resolved yet. I contacted the product manager and others from B&R, but the response from the other side was that we still need to wait for further feedback from the supplier.
