An Operator Interface (OI) is a low-level graphical user interface for specialized computers like a Distributed Control System (DCS), Programmable Logic Controller (PLC), or PAC. It helps to regulate and monitor the processes in industrial settings. The OI offers a remote interface to the push buttons, switches, and gauges located on the actual equipment.
The OI is typically integrated into a ruggedized terminal so that it can be used on the shop floor. Unlike Windows and Mac-based interfaces, OI does not provide the same level of flexibility and rich graphics for the users. However, it enables factory operators to have a simple yet effective control system.
How does an Operator Interface work?
The Operator Interface (OI) is used to implement the control of processes that are critical to industries. The interface basically visualizes the status of the machine or production line, alerts the operator with alarm messages, and enables quick reaction to minimize downtime.
For instance, the OI can show the temperature of a particular machine, and accordingly, the operator can adjust the cooling system to avoid overheating. The OI can also alert operators if the machine is going to overload or shut down unexpectedly. Operators can respond immediately and take necessary actions to prevent a production stoppage.
What is the importance of Operator Interface?
The Operator Interface (OI) is important because it helps operators in manufacturing industries to monitor and control production processes. It is also critical for detecting and addressing any problems before they cause damage to equipment or production.
What is the difference between an OI and a SCADA system?
An OI is generally used for local operator control, while a Supervisory Control and Data Acquisition (SCADA) system provides remote monitoring and control capabilities. OI is specific for controlling and monitoring equipment within a limited range, while SCADA systems monitor entire systems or processes across wide areas.
The Operator Interface (OI) is an essential instrument in industrial settings, allowing operators to control critical processes and track the production status. Though it may not provide the level of flexibility and rich graphics found in other interfaces, it is unique in its own way and allows operators to have better control over their work environment.
