The interrupt section of the slave diagnostic shows information about
interrupt type and cause. It consists of max. 12bytes. For every slave
diagnostic max. 1 interrupt may be sent. The interrupt section is always the
last part of the diagnostic telegram if activated in the parameterization.
If there is a diagnostic event for a channel of a module, there may be a
module error as well as a channel error.
