M4 Err Grp 5

[Daniel]

Hi

Was going through my logged data and found this, M4 Err Grp 5 and would like to know what it is or what it means.
Tryed to upload the data but i can not get it to work as its to big of a file.
Does anyone know what it means?

Each error/status is assigned a value that represents each bit of the error group channel 1, 2, 4, 8, 16, 32, 64, 128
If there are multiple error/statuses on at the same time these numbers add together, so when the error group has a value of 50, that is error 32, 16 and 2.
A bit mask works by filtering the channel so only certain bits have an effect. A bit mask of 50 allows error 32, 16 and 2 to change the result to their corresponding values but any other bits are masked so if bit value 1, 4, 8, 64 or 128 appears they do not affect the result.

What each bit means can be found in the when veiwing the logging setup for the error groups set out with values as follows.
