This “CONFIGURATION TOOL of BACnet GATEWAY for VRF SYSTEM” License Agreement (“LICENSE AGREEMENT”) is a legal agreement between you and Fujitsu General Limited (“FGL”) for the use of CONFIGURATION TOOL for VRF BACnet GATEWAY products consisting of computer software and online, electronic and/or printed documentation (collectively “SOFTWARE PRODUCT” or “SOFTWARE”).
BACnet Gateway for VRF System. The aim of this integration is to monitor and control your Fujitsu VRF air conditioning system, remotely, from your Control Center using any commercial SCADA or monitoring software that includes a BACnet/IP driver. To do it so, the BACnet Gateway for VRF System allows BACnet/IP communication, acting as a server, allowing polling or subscription requests (COV).
Number of refrigerant systems that can be controlled through UTY- Number of Refrigerant systems VBGX 5000 Number of FGL control and status objects available into UTY-VBGX. Number of Objects The number of Indoor Units and Outdoor Units may vary on each project. These parameters can be configured through Configuration Tool (See section 8).
Use the LON connector in the left bottom corner of the gateway in order to connect the VRF network to the UTY- VBGX. Remember to follow all safety precautions indicated by Fujitsu. Modifying some other parameters can affect proper communication.
10. Open the Fujitsu Communication Viewer window and check that there is communication activity, some RX frames. This means that the communication with the VRF network is OK. In case of no communication activity, check that the VRF network is operative and well configured and check also the communication cable used to connect both systems.
8.2 Welcome screen From the welcome screen, access is granted to: the Fujitsu General Limited Website, start a new project, load a previous project from our computer or get the current project running on the gateway. Figure 8.1 Welcome screen 1.
1. Device Name: Device BACnet name and description (Device UTY-VBGX by default). 2. Device Instance: Device BACnet number (144 by default, if more than one UTY-VBGX is present, this have to be a unique number for each BACnet Gateway for VRF System).
8.7 Diagnostic Use this setting to check the current communication status of the gateway on both: BACnet and FGL. Communication with the box, the BACnet side and the Fujitsu system can be check using the viewer available. Figure 8.12 Diagnostic tool 1.
Check the current signal values on both: BACnet and VRF network side (connection to the VRF network and/or BACnet client is required). The Signals Viewer can be used even though only one system is connected to the gateway, BACnet or Fujitsu AC. Therefore, it becomes convenient for supervision and testing the system.
