Troubleshooting Communication Issue with Panelview 800 2711R-T7T: Boot Code Version 8.011 Incompatibility with DH485 Protocol

Question:

I am currently in the process of migrating an application, but have encountered an issue with the Boot Code Version of the panel being at 8.011. This version does not support the dh485 communication protocol, making it impossible to download the firmware version 7.011, which is compatible with dh845. I am seeking assistance in resolving this compatibility issue. Can someone provide guidance on how to address this problem?

After reviewing the Knowledgebase, it appears that there was a hardware update from Series A to Series B for the 7" units alongside the release of Version 8.011 and later firmware. Unfortunately, the newer hardware does not support DH485 communication. This means that if you have a Series B terminal with Version 8.011 or later, it will not be able to support DH485. According to the release notes, Rockwell Automation does not plan to reintroduce the removed legacy communication functionality. It is possible that they decided to remove these features to optimize memory usage or testing procedures, as they may not have been in high demand. If you are encountering issues with PanelView 800 firmware v8.011 and the hardware series changes, you may need to consider using an older terminal or exploring alternative platforms to run your desired applications effectively.

According to Ken Roach's interpretation of the Knowledgebase, a hardware change from Series A to Series B occurred alongside the release of firmware Version 8.011 and later. This new hardware no longer supports DH485 communication. If you have a Series B terminal with firmware 8.011 or later, it will never be able to support DH485. Rockwell Automation does not plan to reintroduce the legacy communication functionality that was removed from these terminals. It is possible that they made this decision to optimize memory usage or testing processes, as the older features were not in high demand. For those needing DH485 support, it may be necessary to locate an older terminal or consider a different platform.

It seems that you're stuck between the proverbial 'rock and hard place'. Unfortunately, if your Boot Code Version doesn't support dh485, there's not much you can do about it directly. But one workaround might be installing an intermediary firmware version that can interact with both your current version and desired version, which might be a bridge to ease this version migration. Always remember to back up before making such changes, just as a precautionary step.

It sounds like you're in quite the pickle, but there might be a workaround. Rather than trying to downgrade your firmware, consider using an interface converter that can bridge the dh485 and dh845 protocols. This way, you won't have to tamper with the Boot Code Version. Just ensure that the converter you select is universally compatible with both these protocols and won't add any significant latency to your communications.
