2. A.Klepper – 01/04/11 Rev.B 2 The OPC-Client has access to the OPC- server via TCP/IP, and present the data points in the BMS as graphics TCP/IP-Communication Different protocolls, e.g. Modbus, LON,KNX BMS Typical OPC application The OPC-Server collect the process datas aia a proprietary field bus from the field devices And provide these as OPC objects in the OPC-server

4. A.Klepper – 01/04/11 Rev.B 4 The CEAG CG-S OPC-Server is a Hardware-driver, which allows a BMS-software (e.g. CGVision) as OPC-client, a communication to CEAG emergency lighting systems with STAR-technology (CG-S Bus). An another BMS software for visualisation, must be able to support the OPC- interface. (e.g. Intouch from wonderware, B-CON etc.) The possible messages for status (e.g. circuit failure), or rather commandos (e.g. start functionstest) are described in a special interface description.
