SCADA & HMI

SCADA (supervisory control and data acquisition) is a system for remote monitoring and control that operates with coded signals over communication channels (using typically one communication channel per remote station). The control system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions. It is a type of industrial control system (ICS). Industrial control systems are computer-based systems that monitor and control industrial processes that exist in the physical world. SCADA systems historically distinguish themselves from other ICS systems by being large-scale processes that can include multiple sites, and large distances.

Such systems are "stratified" (scalable) Due to the nature allows them carried out gradually all control needs of different businesses.

These layers.

Enterprise Resource Management Layer

Production and services to support policy decisions in this layer of the resources required for the planned production of the company are taken and implemented. The services and cooperation between departments, other departments with production management is carried out. Here "Enterprise Resource Planning" (Enterprise Resource Planning - ERP) software is used to support the management function at this level. An integrated SCADA control system in this layer of the lower layer by evaluating the data from business development strategies, policies taken important decisions regarding the detection and businesses.

Layer Management

Cooperation between the departments of businesses or facilities are provided at this level. Decisions are created in accordance with a determined strategy of business management layer in the previous level and the work carried out as well. This layer handles the more a business process manager.

Process Control Layer

Process Control facilities with the realization of monitoring and data collection functions are intended to ensure synchronicity between the layers and machinery. This layer typically contains control devices and SCADA software within the central control room.

Business Control Layer

Defined as enterprises where the physical layer controls. Here carry out the functions of business and connect electronic devices with mechanical interface. Control commands the electrical signals at that level for the operation of facilities, which in turn signals and camera movement, this transformation is collected via electronic sensors. The collected data are converted into electrical signals transmitted to the SCADA system. Drive motors, valves, lamps, speed measurement equipment, proximity detectors, temperature, force and torque sensor electronics are located here. Commands from the SCADA system, the opening of the valves required to be converted into electrical signals in the real world in this layer, ensuring the formation of the movement, such as heaters run and stopped.

SCADA Position

Monitoring Functions (Event and Alarm Processing)
Control Functions
Data collecting
Data Recording and Storage

The logic of all production stages from a single central SCADA monitoring, inspection, the ability to control the data-collection and reporting unit. Because of these features are provided by a large areas.

SCADA Advantages

The system can be monitored at any time
Time and labor earnings
Recording and analyzing production data
Energy monitoring and conservation systems
Suspended condition prevention (compensation etc.).
Be aware of the situation in the field and immediate intervention
Storing intervention system
The risk of failure can be determined in
Get information about the functioning of the system can instantly (switch of status, etc.). There are many great advantages, such as
