METHOD AND ASSEMBLY FOR ACCESS BETWEEN AN APPLICATION OF AN INDUSTRIAL OPERATING AND OBSERVATION DEVICE AND AT LEAST ONE SERVICE

摘要

The invention relates to a method and an arrangement for accessing an application (HMI-A) of an industrial operator control and monitoring device to at least one service, the industrial operator control and monitoring device using a proprietary industrial communication link to a communication infrastructure (HMI-I). connected and connected to an HMI server (HMI-S). The HMI server (HMI-S) is equipped with a message broker (BR), the message broker (BR) being set up for communication with the at least one service by means of a number of open message protocols, with messages and service requests of the application (HMI-A) are exchanged with the message broker (BR) via the proprietary industrial communication link according to a first open message protocol, the message broker (BR) implementing the message and service requirements between the first open message if necessary Protocol and a second open message protocol used by the service, and wherein the message broker (BR) forwards the converted messages and service requests of the application to the service and vice versa. This means that users can implement their services with their environment using the mechanisms they are familiar with and connect them to the HMI system. It is also possible for services of the HMI / SCADA system to be made available via brokers for the purpose of external use and to be consumed by clients with the known and available mechanisms of message-based services.
