Operator Graphics System

• Dynamic graphical representation of plant status
• Operator interaction with the plant using a mouse
• Trending of process variables
• Alarm handling
• Diagnostics for the control system

Picture structures are configured in a hierarchical series, more detail being obtained by pointing and clicking. Dialogue boxes appear prompting for parameters and presenting options. Once selected the commands are transferred to the control system to initiate the operation.

Connection is either by a serial link to a single ACCOS control system or via a network so that up to 254 systems can be monitored and controlled from a single OGS station.
