Abstract
Apparatus for indicating an abnormal program execution by a process controlling computer in, for example, a telecommunication system wherein the different programs, each consisting of one or more program sectors, are called for and executed within certain so-called priority levels. Each priority level includes a counter for supervising the execution of the programs on the level. This counter is stepped, for example, in its forward direction by a clock for measuring the time during which the computer works on the associated priority level and if a certain time limit is exceeded, a warning signal is obtained. For supervising the work of a certain program sector a second counter is arranged which is stepped in either direction by means of the clock and if a certain time limit is exceeded an alarm signal is obtained. The warning and alarm signals are delivered to the central processing unit of the computer via a control register for initiating an instruction program corresponding to the alarm or warning signal, respectively.
