A safety controller controls an automated installation on the basis of project data representing an individual application running. The safety controller has a plurality of controller hardware components. At least some controller hardware components have a respective project data memory. The project data memories each are designed to store project data supplied to them. The safety controller includes a connecting unit, such as a communication network, which connects the controller hardware components to one another. The safety controller also has a distribution unit for distributing at least some of the project data via the connecting unit to at least some of the project data memories.

Safety controller and method for controlling an automated installation

An installation comprises at least one sensor for providing sensor data representing a real system state of the installation and at least one actuator for acting on the real system state. A controller for controlling the installation comprises a data memory for storing the sensor data and a program memory for storing a machine code program. A programming tool for programming the controller includes a program editor, a debugging tool and a compiler. A machine code program is executed on the controller while the debugging tool is activated, and the debugging tool determines a reverse relationship between the machine code running on the controller and at least one high level control instruction shown in the program editor, thereby linking at least one high level control instruction to a real system state during the execution of the machine code program.

Method and device for programming an industrial controller

A method for creating a user program for a safety controller designed to control an automated installation having a plurality of sensors and a plurality of actuators involves several programming steps. The user program comprises a first program portion, in which safety-related program variables are processed in failsafe fashion, and comprises at least one second program portion, in which non-safety-related program variables are processed, wherein failsafe processing is not necessary for the non-safety-related program variables within the second program portion. The method steps involve a step of defining a number of safety-related program variables, a step of defining a number of non-safety-related program variables, a step of selecting a safety-related program variable from the number of safety-related program variables, a step of selecting a first non-safety-related program variable from the number of non-safety-related program variables, wherein the first non-safety-related program variable is repeatedly assigned an instantaneous value when the user program is executed, a step of defining at least one assignment condition which is processed when the user program is executed, a step of defining an association which associates the selected first non-safety-related program variable with the selected safety-related program variable, wherein the instantaneous value of the selected first non-safety-related program variable is assigned to the selected safety-related program variable depending on the assignment condition, when the user program is executed.
