METHOD FOR OPERATING AN AUTOMATION NETWORK, AUTOMATION NETWORK, AND COMPUTER PROGRAM PRODUCT

摘要

The invention relates to an operating method for an automation network (1) having a gateway device (2) and a plurality of network devices (3, 4, 5), wherein the network devices (3, 4, 5) subscribe to subscription data (AD₂) from the gateway device (2) by means of a respectively associated subscription identifier (AK₂) and publish publication data (PD₁) under a respectively associated publication identifier (PK₁). The gateway device (2) publishes publication data (PK₁) as subscribed subscription data (AD₁) under a respective subscription identifier (AK₁). The network devices (3, 4, 5) are a field instrument device (4) and a database device (3), which subscribe, save, provide and/or publish measurement (MD) and/or control data (SD) of the field instrument device (4), device data (GD) via network devices (3, 4, 5) present in the automation network (1), and user data (BD) via users of the network devices (3, 4, 5). The data (MD, SD, BD, GD) are transmitted via the gateway device (2) according to a specified protocol by subscribing and publishing.
