The invention relates to a protection circuit () for an access-arbitrated bus system network, comprising a fault detection device for detecting a fault status in a sub-network of the overall bus system network; and a separating device for separating the sub-network from the overall network when a fault status is detected in said sub-network.

Protection circuit for an access-arbitrated bus system network

A measuring apparatus has a sensor element that produces an output signal proportional to a variable to be measured. An integrator which, beginning at a starting value, integrates the output signal from the sensor element. A comparator is connected downstream of the integrator, compares the output signal from the integrator with a threshold value, and outputs an output signal corresponding to the result of the comparison. A reset device that is likewise connected downstream of the comparator and resets the integrator to the starting value at specific times. This is a simple way of achieving integrability in autonomous modules.
