When a process station with Webpanel is to be restarted remotely (because of some configuration changes, CF commit and reboot for permanent saving of changes) there happens that the OS closes network connections (thus remote communication is terminated) and then asks if the Webpanel service has to be quit. This prompt can not be remotely acknowledged, and the station seems to stop responding – it does not reboot.
Solution: if there is a need of remote restart of a station with Webpanel, shut down the web service first using Web Panel Win Service Manager, and then reboot the station.
The Building Automation Control Network (BACnet) protocol is not new to building management systems. In process stations, however, it appears only gradually, especially for its not quite easy implementation. Unlike relatively simple communication protocols such as Modbus, BACnet defines a number of services and objects that make it easier for application engineers to work with programming and commissioning technologies.
