Hi

Anyone could explain me the issue with the block not working please? 

I don`t understand what is the internal error message.

Thanks

Hi,

try to look to a BACnet browser on the connected object. It maybe visible reason there.

Hi,

If you look at the block it just does not make sense. The CMD_M should select the value 4 and not create an internal error. 

When configuring it as a BACnet object, it`s saying the object is not accessible. 

Where can we find some documentation on those error code? 

Are you able to try this on your ABT site and let me know if you get the same error please?
