OPC Data Access
OPC Data Access is a group of standards that provides specifications for communicating real-time data from data acquisition devices. The specifications focus on the continuous communication of data, and deals with real-time data only, not historical data.
OPC Data Access allows the status of Gallagher Command Centre items to be shared with a third party system, and also allows the status to be overwritten. For instance, a third party OPC client system could monitor the status of Gallagher perimeter sensors, and be alerted when an alarm is raised.
