Runtime server for simultaneously executing multiple runtime systems of automation installation

Abstract

The invention relates to a runtime server (100) for simultaneously executing multiple runtime systems (101) in an operating system (103) for a data processing installation for controlling an automation installation on the basis of an installation control program, wherein the runtime systems (101) are designed for real-time execution of the installation control program, comprising: at least two runtime systems (101) for executing application modules (105) of the installation control program, wherein at least one application module (105) for executing an application of the installation control program is installed on each runtime system (101), wherein each runtime system (101) has a data transmission interface (107) for data transmission between runtime systems (101) and / or between application modules (105), wherein each runtime system (101) has an I / O configuration (109) that defines an association between at least one variable of the application modules (105) of the runtime systems (101) and at least one hardware address of a hardware component (113) of an automation installation (112) to be controlled, an I / O interface (111) for data interchange between the at least two runtime systems (101) and the hardware components (113) of the automation installation (112) having at least one I / O input (115) and / or I / O output (117), and an I / O mapping intermediate layer (119), wherein the I / O configurations (109) of the at least two runtime systems (101) are mapped in the I / O mapping intermediate layer (119). The invention further relates to a computer program product (200) for executing the runtime server (100).

Description

technical field [0001] The invention relates to a runtime server for the simultaneous execution of several runtime systems in an operating system of a data processing device for controlling an automation device. The invention furthermore relates to a computer program product having program code means for executing a runtime server and a runtime system. The invention also includes an automation device. Background technique [0002] This patent application claims priority from German patent application DE 10 2019 117 954.8 of 03.07.2019, the disclosure content of which is hereby incorporated by reference. [0003] In industrial automation, memory programmable and numerical control (SPS / NC) is increasingly implemented in software on efficient standard hardware, such as an industrial PC. In contrast to conventional SPS / NC, which is executed on separate computing components, so-called soft SPS / NC runs under the host operating system of the data processing device, for example un...

Problems solved by technology

[0007] Despite the advantages that can be obtained by modularizing the control program, there is also the following problem: In order to perform changes, modifications or upgrades to the existing control program or to the individual program modules of the control program, the control program must at least update the change or upgrade to the existing must be interrupted during the time period with the control program

However, an interruption of the control program also means an interruption of the control and thus of the operation of the automation system every time.
