The base unit contains information about the
` Link module (in order, defective, no supply voltage)
` Status of communication with the decentralised modules (data valid,
data invalid)
If the connection to a decentralised module is interrupted or there is a
major error on the decentralised module, the inputs on the devices con-
nected to the link module are set to zero. The base unit remains in a RUN
condition.
