The OPC server (datasheet) acts as a master on Johnson Controls Metasys N2 network consisting of a mix of slave devices communicating using N2 (original Johnson Controls protocol) or N2Open protocol. N2 and N2Open are Optomux-based protocols used in HVAC (Heating, Ventilation and Air Conditioning) and other building automation networks. The server supports DC, DX, TC, VND and many other N2/N2Open devices, and is extensible using "hardware type definition" files.
New: OPC Server for Johnson Controls N2 now supports OPC UA (Universal Architecture) specification.
New: OPC Server for Johnson Controls N2 now supports 64-bit versions of Windows operating system.
Can be used to replace the NCM (Network Control Module) and enable OPC access to N2 slaves. Optionally, the OPC server can also pass through (forward) communication from other master, such as the NCM unit.
The server can handle multiple N2 networks simultaneously, and up to 255 slave devices on each network. The computer can connect to an N2 network via serial port, or using TCP through an Ethernet/serial convertor.
Configuration program with rich user interface is supplied with the server. You can use both the items pre-defined for a hardware type of your device, or add your own named items. The configuration is stored in an XML file. The server can run as Windows Service or Local Server.
