2. A.Klepper – 01/04/11 Rev.B 2 LAN-connection between PC with CGVision and PC with BMS Software LAN (RJ45) Ethernet (LAN) with TCP/IP USB Building Managment System (BMS) (e.g. TAC – Vista) PC Workstation with CGVision LAN (RJ45) IP-Interface Client 1 ZB-S CG-S Bus / FTT10A ZB-S ZB-S Systems BMS as OPC-Client IP-Interface Client 2 ZB-S CG-S Bus / FTT10A ZB-S ZB-S Systems incl. OPC-Server CG-S/IP-Interface
