Data generator

A data generator is a device that can simulate and reproduce miscommunication in a communication network .

Such a device consists of a programmable microprocessor , a storage medium , interfaces and one or more channels for connecting the communication network. Data generators usually have their own energy supply (e.g. from an accumulator ). Data is fed into the communication via the interface . A data generator is also configured for its use via one of these interfaces (e.g. the messages to be sent, response messages to received data, data to be sent cyclically, etc.).

Applications

Data generators are used to control and test control units in development, production and service, for system tests with deliberately generated fault data , for sending user- configured telegrams or data in an industrial environment and for ECU emulation.

Specifications

A distinction is made between data generators for "home use" and those for professional use. The latter can u. a. work independently in stand-alone mode after parameterization , have a significantly higher level of robustness and lower power consumption and are compatible with 12/24 V on-board voltages in automobiles and trucks .
