Abstract
A measurement or protective device has an interface for establishing a connection to at least one measurement transducer and a further interface for connecting to a superordinate data bus. In order to allow the measurement or protective device to be used in a particularly universal manner and to make it possible for complex protective systems to be constructed in a particularly cost-effective manner, a communication unit is provided in the measurement or protective device. The communication unit is connected to both interfaces, can be directly connected to the measurement transducer via the interface, can be connected to the superordinate data bus via the further interface, forms messages and transmits them to the superordinate data bus.

1-17. (canceled)
A measurement or protective device, comprising:
- a first interface for establishing a connection to at least one measurement transducer;
- a second interface for connecting to a superordinate data bus;
- and
- a communication unit connected to said first and second interfaces, said communication unit being directly connected to the measurement transducer through said first interface, said communication unit being connected to the superordinate data bus through said second interface, said communication unit receiving phase-conductor-related samples from the measurement transducer for forming sampling-time-related messages and transmitting the sampling-time-related messages to the superordinate data bus.
A protective system, comprising:
- a measurement transducer;
- a process bus;
- a superordinate data bus;
- a device selected from the group consisting of measurement devices and protective devices, said device containing:
- a first interface for establishing a connection to said measurement transducer;
- a second interface for connecting to said superordinate data bus;
- a communication unit connected to said first and second interfaces, said communication unit being directly connected to said measurement transducer through said first interface, said communication unit being connected to said superordinate data bus through said second interface, said communication unit receiving phase-conductor-related samples from said measurement transducer for forming sampling-time-related messages and transmitting the sampling-time-related messages to said superordinate data bus;
- a first 3-port network connection having two external ports connected to said measurement transducer through said process bus;
- and
- a second 3-port network connection having two external ports connected to said superordinate data bus being a station bus.
