What does the error message "Too many data" mean?

FAQ #101554

 

Symptom
The M-Bus communication is working but the M-Bus Master FBox indicates an error on the output "Err" with code 36: "Too many data".

Reason
This error message is generated because that the buffer is not big enough to handle all the received data (the received telegram contains too many data for that all information could be stored in the configured buffer).

Solution
Increase the buffer size in the FBox "M-Bus Master", by default it is configured with 20 registers so increase it to e.g. 50 (100 is the maximum).
