A data processing system, comprising several distributed processing units which are connected to a remote central monitor and test station in which the state of each distributed processing unit is monitored by the transmission of test and diagnostic signals. Each processing unit comprises a simulation unit which comprises a microprocessor and test sequences for decoding and simulating these commands and, after their execution by the central unit of the processing unit, for transmitting the results to the central station for analysis. Moreover, the simulation unit is capable of detecting errors in the simulation and the execution of the commands and of supplying the central station with a warning.
