A method and system for operating a bus master on a field bus on the basis of the master/slave principle in the event of a fault. The field bus has at least one slave connected to it and the bus master runs a separate state table for each connected slave. The state table stores the operating state of each individual slave and each state table is deleted when initialization takes place for the first time. In the event of a fault, the bus master is reinitialized such that a check is run to ascertain whether full initialization has taken place for each connected slave as assumed, and, if it has, the content of each state table is retained in unmodified form, and, if it has not, the state table for the affected slave is deleted and the bootstrap initialization is imposed.
A method of operating a bus master on a field bus in the event of a fault, said field bus having at least one slave connected to it and said bus master running a separate state table for each connected slave, which stores the operating state of each connected slave, each state table being deleted when initialization takes place for the first time, said method comprising the steps of:
