In Table 31, the term multi-vibrator is used to indicate a network
variable whose state is changed regularly. The receiver expects this value
to change state within a certain interval. If it does not, a communication
fault is generated. The term comm. status is used to indicate a network
variable whose state is dependent on that particular MP581's EX2 and
BMTX communication status. If either are down, a communication fault
is generated.
