To enable an addition or a removal of a control into or from a communication line without an interruption of the ongoing communication of the communication line, a method is provided of adding a control into a network of at least one first and one second control, which are provided for operating actuators, during an operation of the network, wherein the first and second controls are connected to one another in a communication line and communicate with one another via a first transmission connection of the first control and a second transmission connection of the second control; and wherein each control has an unambiguous identifier, comprising the steps of providing a third transmission connection and a fourth transmission connection between the control to be added and the first control to be connected upstream of the control to be added; providing a fifth transmission connection and a sixth transmission connection between the control to be added and the second control to be connected downstream of the control to be added; and activating the third to sixth transmission connections between the first and second controls and the control to be added on the simultaneous deactivation of the first and second transmission connections between the first and second controls and methods of removing a control from a network of at least one first and one second control and the control to be removed.

Methods of adding or removing a control into/out of a network and apparatus for carrying out said methods

The invention relates to a method for the programming of a safety controller to be interconnected with encoders and actuators, wherein a wiring plan or a specific wiring is first prepared, whereupon an automated programming of the safety controller takes place using the wiring information.

Method for the programming of a safety controller

The invention relates to an apparatus for the generation of a program for a programmable logic controller having a programming input unit for the selection and compilation of a plurality of symbols, a generation unit for the generation of a program code for the programmable logic controller from an arrangement of symbols compiled at the display unit of the programming input unit. In accordance with the invention an investigation unit for investigating the resulting possible influences of input signals of the programmable logic controller, onto output signals of the programmable logic controller at the actuator outputs from the arrangement of symbols generated by the program code or compiled at the display unit of the programming input unit is provided. In accordance with the invention an implementing unit for implementing the possible exertion of influence in a matrix and a display unit for the display of the matrix are also provided. The invention further relates to a programming device for a programmable logic controller having such an apparatus for the generation of a program, a corresponding method for programming a programmable logic controller and a corresponding computer program product.

Programming programmable logic controllers using exertion influence in establishing matrix parameters

The present invention relates to an apparatus for configuring a bus system which includes a plurality of participants as well as a bus master and a safety monitor having an input unit by means of which suitable configuration information can be entered and/or selected for the configuration of the bus system and having a configuration unit configured to configure both the bus master and also the safety monitor by means of at least a piece of identical common configuration information input or selected via the input unit. The invention further relates to a method which can be carried out by the apparatus in accordance with the invention.

Apparatus and method for configuring a bus system

A safety controller () having at least one input () for the connection of a sensor (), at least one output () for the connection of an actuator (), at least one communication interface () for the connection of a further safety controller (-), to exchange control relevant information as well as having and also having a control unit () is provided which is configured to carry out a control program which generates a control signal at the outputs () in accordance with predeterminable logic rules in dependence on input signals at the inputs () and/or in dependence on the control relevant information. In this respect the communication interface () is configured for the connection of safety controllers (-) in a line arrangement, in which each safety controller (-) has a neighboring safety controller (-) arranged as a predecessor and/or a neighboring safety controller (-) arranged as a successor, and the logic rules process control relevant information of a connected predecessor and/or a connected successor and communicate the so determined control signals as control relevant information to a connected predecessor and/or a connected successor.
