DEVICES, SYSTEMS AND METHODS OF CONFIGURING PROGRAMMABLE LOGIC CONTROLLER Russian patent published in 2011 - IPC G05B19/05 

FIELD: information technology.

SUBSTANCE: system for automatic configuration of a user interface in a programmable logic controller comprises a user interface tenderer which can be adapted to render a plurality of distinct user interfaces. Each user interface can be adapted to configure the corresponding software application. The user interface tenderer can be adapted to automatically provide a first user interface if the said PLC executes a control program, and a second user interface if the said PLC does not execute the said control program. The first user interface can be adapted to simplify debugging of the selected software application and to receive debugging input from the user. The second user interface can be adapted to provide the current set of configuration parametres and to receive configuration input from the user. In response to the configuration input, the second user interface can be adapted to change configuration parametres from the current set of configuration parametres.

EFFECT: automatic provision of a user interface based on information on whether the programmable logic controller executes the control program.
