Channel-related diagnosis
Information indicating the error content in 3byte per module (sensor amplifier) is stored
in Octet 20 to 67. The frame length of the diagnosis changes depending on the number
of module (sensor amplifier) connected (3 + 3 x [number of module (sensor amplifier)
connected]).
Also, Information of the module (sensor amplifier) for which the diagnostic function is set
to Disable for the parameter settings is deleted from the frame and subsequent data is
offset.
