Abstract

In a system where the power is controlled by a microprocessor, power error logouts normally consist of data bits. In order to analyze a logout, the user must interpret the data bits. It is desirable to provide a program which can analyze the data bits from the power logout and display the logout information in a user friendly format. Such a program would have three significant advantages: 1. An engineering evaluation of the sequence of events leading up to the error would be provided. This would help the user to determine the most logical failing power component. 2. A display of the hardware control latches and the error latches, related to the power fault, would be provided. 3. A display of the actual names of the hardware control latches and the error latches would be provided. Fig.

POWER Logout Detail Display Program

In a system where the power is controlled by a microprocessor, power error logouts normally consist of data bits. In order to analyze a logout, the user must interpret the data bits. It is desirable to provide a program which can analyze the data bits from the power logout and display the logout information in a user friendly format. Such a program would have three significant advantages: 1. An engineering evaluation of the sequence of events leading up to the error would be provided. This would help the user to determine the most logical failing power component. 2. A display of the hardware control latches and the error latches, related to the power fault, would be provided. 3. A display of the actual names of the hardware control latches and the error latches would be provided. Fig. 1 illustrates an example of the type of output which would be provided as a result of this program. This figure describes each area of the display. The display features two major areas. The first section is called "CONTROL LATCHES AT TIME OF ERROR". This section illustrates the status of the hardware latches that control the power system. The actual names of the control latches are used. These control latches are displayed in the same sequence as they are activated to control the power system. Only the activated control latches related to the power fault will be displayed. The second section is called "POWER ERRORS". This section displays the erro...
