ACOPOSmulti power supply 8BVP440HW firmware issue

I have a machine with 8BVP440HW power supply with firmware issue. I sdm I can see this:

The hardware tab, I got this firmware:

The communication is good by checking on the SDM but due to the power supply issue, I can’t power up the servo drives behind:

I did use a B&R function block to read out the details:

The working version should look like this:

And all the runtime are configured below:

At hardware, I can see that the power supply LED “ERR” is blink slowly.

How can I downgrade the firmware?

Hi @Swee_Hoe , your power supply is 8BVP0440HW00.000-3 that’s why you need at least ACP10 ARNC0 5.24.1. There is a note in the Help under Motion control > mapp Motion > General information > Version 5.24.1, but I don’t see similar note for Motion control > ACP10/ARNC0…
On the menu Tools > Upgrades…select at least the version 5.24.1

I think this is the “available” solution until now. I do a test with a completely new project that only have the power supply, it work with 5.24.1 and the power supply work well:

But the problem is when I changing the runtime to 5.24.1, I need to upgrade the “mapp services” too:

I’m not sure upgrade the “mapp services” version will affect the rest of the code or not.
We did a lot hard work to maintained same pieces of source code. It seem it can’t work with this way when there is new version of hardware introduced. BTW we use ACP10 instead of “mapp Motion”, so I never notice there is a note there and there is not log in the PLC state that I need to upgrade the firmware. The error message I showed was get from a function block. Thanks for the help.

Usually within a version line (so in this case “5.xx”), no incompatible changes happen.

You can check on the linked page that only additions and improvements happened in 3 or 4 or the versions after 5.17.0 and no (user facing) changes at all in others (this is due to the dependency between the mapp packages, which forced a release for packages that had no or no relevant changes)

→ You can upgrade those packages

Yup, firmware can only support things that are known by the time the firmware is released :wink:


Addition: I’d go for the latest ACP10 (5.27.1), not 3 versions old once more, when you are already upgrading anyway
