Abstract
For the purpose of controlling safety functions as part of a system controller which is not oriented to safety functions in an automation system, the invention provides safety modules having a sound functionality and provides a safety protocol which transmits data in the form of safety messages, wherein input and output parameters from each safety module are encapsulated by the safety protocol, and the individual safety modules are logically combined with one another in terms of data and flow by means of a data transmission link in line with the system's safety functions which are to be controlled, the data interchange taking place between the safety modules on the basis of the safety protocol.
Claims26
A method for controlling safety functions as part of a system controller which is not oriented to safety functions, in which safety modules having a sound functionality are provided and a safety protocol which transmits data in the form of safety messages is provided, wherein input parameters and the output parameter from each safety module are encapsulated by the safety protocol, and the individual safety modules are logically combined with one another in terms of data and flow by means of a data transmission link in line with the system's safety functions which are to be controlled, the data interchange taking place between the safety modules on the basis of the safety protocol.
A method for controlling safety functions as part of a system controller which is not oriented to safety functions, in which safety modules having a sound functionality are provided and a safety protocol which transmits data in the form of safety messages is provided, wherein input parameters and the output parameter from each safety module are encapsulated by the safety protocol, and the individual safety modules are logically combined with one another in terms of data and flow by means of a data transmission link, the data interchange taking place between the safety modules on the basis of the safety protocol, wherein in an implementation step of the safety protocol the logic combination of the safety modules in terms of data and flow is stipulated in line with the system's safety functions which are to be controlled, each safety module being assigned a unique identifier.
An apparatus for controlling safety functions in an automation system as part of a system controller which is not oriented to safety functions, comprising safety modules having a sound functionality and comprising a safety protocol which transmits data in the form of safety messages, in which input parameters and the output parameter from the safety modules are encapsulated by the safety protocol, and has a combinational logic unit which logically combines the safety modules with the other safety modules in terms of data and flow in line with the system's safety functions which are to be controlled.
An apparatus for controlling safety functions in an automation system as part of a system controller which is not oriented to safety functions, comprising safety modules having a sound functionality which are logically combined with one another in terms of data and flow by means of a data transmission link and comprising a safety protocol which transmits data in the form of safety messages, in which input parameters and the output parameter from the safety modules are encapsulated by the safety protocol, wherein a logic tool in the safety protocol which is designed to stipulate, in an implementation step of the safety protocol, the safety modules' logic combination in terms of data and flow in line with the system's safety functions which are to be controlled and to assign a unique identifier to each safety module.
