A method for operating an application program for executing in an electric control unit for a drive system includes managing at least one application parameter using an application parameter manager.

A controller includes control function circuits that are connected to each other and control a multi-axis control machine. Each of the control function circuits performs a respective control function upon receipt of a control signal from another control function circuit of the control function circuits, and the control signal corresponds to a predetermined interface standard determined from the control function.

A control device (7) for a system controlled by a controller with an evaluation unit (9) and at least one acquisition unit (17a, 17b) that is connected to the evaluation unit (9). Depending on input values that are input in the acquisition unit (17a, 17b), an operating mode selection can be performed and/or an access authorization can be granted. Output values generated in this manner can be output to the controller via an output stage (8).

A flexible expandable automation device includes: a main control unit; and at least two I/O-units connected to the main control unit and to each other via an I/O-bus. The I/O-bus works according to a daisy-chain technique. The I/O-bus has a bus signal line and a daisy-chain-control-line. Each I/O-unit has a daisy-chain-control-IN-port for receiving a daisy-chain-control-signal as a daisy-chain-control-IN-signal and a daisy-chain-control-OUT port for delivering the daisy-chain-control-signal as a daisy-chain-control-OUT-signal to a next adjacent I/O-unit. Each I/O-unit has an I/O-module carrier and a pluggable and unpluggable I/O-module. The daisy-chain-control-IN-port and the daisy-chain-control-OUT-port are part of the I/O-module carrier. Each I/O-module-carrier has a hot-swap-control unit that, in case of an unplugged I/O-module creating an interrupted daisy chain, automatically bridges the interrupted daisy chain.

A safety control unit includes: a memory; a computation control part; and an input and output unit for connecting the computation control part to a safety input device and an output device to be safely controlled. A system program includes a data refresh program for executing a data refresh of safety control data of the safety input device and the output device and the control data of the memory via the input and output unit. If the computation control part receives a change of a control program, the computation control part stops executing the control program. The computation control part executes the change of the control program while executing a part of the system program including the data refresh. The computation control part resumes executing the control program.

Arrangement and method for securely executing an automation program in a cloud computing environment, wherein the automation program is installed on computer hardware in a public IT infrastructure, and wherein the computer hardware is connected via a data connection to a cloud server, where the connection and a dedicated runtime environment of the computer hardware are configured such that the automation program is transferrable onto the computer hardware and its execution can be monitored via the server and data connection, such that the automation program and sensitive information, i.e., recipes, instructions and/or method steps, contained therein can be executed in a protected environment, effective protection against interception is achieved and such that the dedicated hardware can be matched to a possibly pre-existing automation program so that existing automation programs can execute in the cloud or be made available without modification and further system tests, certifications and other costly adaptation steps.

The device includes an electric energy source to which an inverter is power-connected, whose output is three-phase with symmetrical power distribution. It further includes an inter-phase power transfer module which is power-connected to the inverter and comprises at least one first power board including at least three power transistors. The inter-phase power transfer module has a data interface and has a first output with asymmetrical power distribution into three phases, wherein the first output is further connected to a distinctive nodal point, this distinctive nodal point being power-connected to a load. Through a measuring module, the PLC control system is also connected to the distinctive nodal point, the PLC control system being further connected also to the inverter and the data interface. This arrangement ensures that the power supplied to the load reflects in each phase the power consumed by the load. The device further offers additional possibilities to control energy production, consumption and storage.
