A safety controller for controlling an automated installation in accordance with a user program has a plurality of control components. At least some of the control components have a respective data bus interface. The data bus interface is designed to receive and send data. The safety controller also has a data bus to which the plurality of control components are connected via the respective data bus interfaces for the purpose of interchanging data. A configuration interface is designed to receive configuration data ascertained on the basis of association data generated by a programming tool. The configuration data determine at least one characteristic of the data bus or of at least one data bus interface.

Safety controller for controlling an automated installation and method for generating a user program for a safety controller

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

A safety controller designed to control an automated installation having a plurality of sensors and a plurality of actuators. A method for generating a user program for the safety controller comprises the step of generating a source code having a number of control instructions for controlling the actuators and having a number of diagnosis instructions for producing diagnosis reports. Safety-related program variables are processed in failsafe fashion during execution of the control instructions. A machine code is generated on the basis of the source code. At least one checksum is determined for at least some of the machine code. The diagnosis instructions are ignored for the determination of the checksum.

Method and apparatus for generating an application program for a safety-related control unit

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 new method and to a new programming tool for creating a user program for a safety controller is disclosed. The new method and programming tool exploit a matrix-type organization of occurring programming tasks. Itemized software components allocated to specific hardware components are combined with aspect blocks that enable programming grouped according to functional control aspects of the system to be controlled.

Method and programming tool for creating a user program for a safety controller

A safety controller for controlling an automated installation which has a plurality of sensors and a plurality of actuators, comprises a control unit to which a plurality of control input signals are supplied by the sensors. The control unit produces a plurality of control output signals in an automatic mode on the basis of the control input signals in accordance with a user program running in said control unit. The plurality of control output signals is used to actuate the plurality of actuators. The safety controller also has a diagnosis evaluation unit to which a number of diagnoses input signals are supplied. The diagnosis evaluation unit takes the diagnosis input signals as a basis for ascertaining which of a plurality of operating states is present at a defined instant of time. The diagnosis evaluation unit produces an operating state data record which represents an ascertained operating state. The safety controller also has an interface for a display unit in order to display diagnosis reports. The operating state data record includes a plurality of diagnosis data and a Boolean status indicator. The control unit actuates at least one actuator on the basis of the Boolean status indicator contained in the operating state data record.

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.
