Objective: Status of devices in plant, PID parameters (Set value, Present value & output), important process variables as temperature, pressure, flow, levels etc. may be changed or need to change anytime that is why these variable condition must be in observation to ensure healthy operation of a plant. There is no available software or control system in Bangladesh to solve this problem. This control system ensures the Observation, Operation and Control of any industry from a suitable position. Feature: It can observe continuously the devices status (on, off, dozing rate (0 to 100 %), level high/low, continuous level (0 to 100 %), open/close (0 to 100 %) PID process regulators etc. without any command and able to indicate any instantaneous changes of state of devices in field. Any plant can be operated (Automatically / Manually) from a suitable place. Using feedback control system, it can control an industry automatically. # It can make a printable report about the important parameter of a plant. Fault location can be detected (software, PLC, in-field device) easily. # From remote location it can observe, operate and control any plant.
