Programming PLC, HMI, SCADA
For the purpose of improving performance, increasing accuracy, utility and intelligence of industrial machinery systems. Cooperate or contract with machine manufacturers, install systems, works with automatic control process.
SCADA: Remote monitoring, remote control system.
The Supervisory Control and Data Acquisition (SCADA) system has been under development for more than 40 years, from a single, distributed model to a distributed network architecture. Fast, flexible, accurate and long distance. In addition, SCADA has moved from proprietary to hardware and software standardization, reducing the cost of upgrading, commissioning and maintenance, and providing management with real-time information to support Planning, monitoring and decision making. SCADA systems are very important components in most of the country's most critical infrastructures such as: • Generator, transmission and distribution facilities. Electric power • oil refinery and pipeline management system • water filtration and distribution system • chemical production and processing system • railway system and mass transport.
HMI: Monitor, control system automatically
The HMI is an acronym for Human-Machine-Interface, a communication device between the operator and the machinery. Strictly speaking, any way that humans "interface" to a machine is an HMI. For example, the microwave on-board sensor is an HMI, the remote control on the washing machine, the remote operating software selection panel on the TV, and the HMI, which allows the user to monitor and control commands. all system. The HMI has a graphical interface, which gives users an intuitive view of the state of the system.
Advantages of HMI:
- Operator support.
- There are many types of compact specifications.
- Low power consumption.
- Mobile when needed.
- Improved reliability
- Higher economic performance.
Compatible with many market sectors.
PLC: Central Process Controller System.
Programmable Logic Controller (PLC) is designed
To replace the traditional control method using relays and loose bulk devices,
And it creates an easy and flexible device control facility based on programming
On basic logic commands. In addition, PLC can perform other tasks as well
Then, count, and so on, which adds to the control of complex operations, even with
The smallest PLC type. The operation of the PLC is to check all signal status at the input,
Taken from the control process, execution of logic is programmed and clicked
Control signals for the corresponding external device.
