With MXPLC serial number 48800 and higher it may happen that the process station restarts periodically after about a minute. To fix it, the cover must be open and the watchdog-blocking jumper must be removed. See the image to locate the jumper – the red circle close to the battery.
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.
