Response to module errors

A module error of one of the connected modules (e.g. HW-defect) is

de-tected by the BL 250/B and a corresponding status message is sent

to thebus master. The error is indicated on the status LED (red)

Behavior at sensor failure on a connected module

A sensor failure on an analog input of a connected module is forwarded

asstatus message to the K-Net master. The status LED of the BL

250/Bre-mains on green.
