Consecutive bytes contain the diagnostics flags for Module 8 through 15, 16 through 23, etc.
The Module related diagnostics information is usually followed by the Channel related diagnostics, which con-
tain the actual diagnostics data per module.
Channel Related Diagnostics
Channel related diagnostics contain diagnostics information related to a specific channel in a configured I/O
module, e.g. over peak current detected on current input channel 2, module 0.
The Channel related diagnostics information entry in the diagnostics message, always consists of three bytes,
which are outlined below. From these bytes the actual event can be deducted.

When set, this bit indicates that there is Diagnostics information pending related
to configuration module 0, i.e. the first configuration module.
When set, this bit indicates that there is Diagnostics information pending related
to configuration module 1.
When set, this bit indicates that there is Diagnostics information pending related
to configuration module 2.
When set, this bit indicates that there is Diagnostics information pending related
to configuration module 3.
When set, this bit indicates that there is Diagnostics information pending related
to configuration module 4.
When set, this bit indicates that there is Diagnostics information pending related
to configuration module 5.
When set, this bit indicates that there is Diagnostics information pending related
to configuration module 6.
When set, this bit indicates that there is Diagnostics information pending related
to configuration module 7.

Error Identifier byte
These bits contain the number of the configuration module, to which the channel,
reporting diagnostics belongs. The module number ranges from 0 to 63.
Fixed to 10.
The combination of bit 6 and 7 indicate the type of diagnostics, i.e. 10 indicates
Channel related diagnostics data.
