Automation & Intelligent Systems
AUTOMATION also referred to as AUTOMATIC CONTROL, is the use of various CONTROL SYSTEMS for operating equipment such as factory machines, heat treating and curing ovens, telecommunication equipment, …etc. with minimal or reduced human intervention. Automation is achieved by using various means including mechanical, hydraulic, pneumatic, electrical, electronic and computers in combination.
An INTELLIGENT SYSTEM on the other hand is a machine with an embedded, Internet-connected computer that has the capability to gather and analyze data and communicate with other systems. Intelligent systems require security, connectivity, ability to adapt according to current data, capability for remote monitoring and management. EMBEDDED SYSTEMS are powerful and capable of complex processing and data analysis usually specialized for tasks relevant to the host machine. Intelligent systems are all around in our daily lives. Examples are traffic lights, smart meters, transportation systems and equipment, digital signage. Some brand name products we sell are JANZ TEC, KORENIX, ICP DAS, DFI-ITOX.
AGS-TECH Inc. offers you products that you can readily purchase from stock and integrate into your automation or intelligent system as well as custom products designed specifically for your application. As the most diverse ENGINEERING INTEGRATION provider we pride ourselves with our capability to provide a solution for almost any automation or intelligent system needs. Besides products, we are here for your consulting and engineering needs.

Industrial control systems are computer-based systems to monitor and control industrial processes. Some of our INDUSTRIAL CONTROL SYSTEMS (ICS) are:
- Supervisory Control and Data Acquisition (SCADA) Systems : These systems operate with coded signals over communication channels to provide control of remote equipment, generally using one communication channel per remote station. The control systems may be combined with data acquisition systems 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. SCADA systems are different from other ICS systems by being large-scale processes that can include multiple sites over large distances. SCADA systems can control industrial processes such as manufacturing and fabrication, infrastructure processes such as transport of oil & gas, electric power transmission, and facility-based processes such as monitoring & control of heating, ventilation, air conditioning systems.
- Distributed Control Systems (DCS) : A type of automated control system that is distributed throughout a machine to provide instructions to different parts of the machine. Contrary to having a centrally located device controlling all machines, in distributed control systems each section of a machine has its own computer that controls the operation. DCS systems are commonly used in manufacturing equipment, utilizing input and output protocols to control the machine. Distributed Control Systems typically use custom designed processors as controllers. Both proprietary interconnections as well as standard communications protocols are used for communication. Input and output modules are the component parts of a DCS. Input and output signals may be either analog or digital. Buses connect the processor and modules through multiplexers and demultiplexers. They also connect the distributed controllers with the central controller and to the Human–machine interface. DCS are frequently used in:
-Petrochemical and chemical plants
-Power plant systems, boilers, nuclear power plants
-Environmental control systems
-Water management systems
-Metal manufacturing plants
- Programmable Logic Controllers (PLC) : A Programmable Logic Controller is a small computer with a built-in operating system made primarily to control machinery. PLCs operating systems are specialized to handle incoming events in real time. Programmable Logic Controllers can be programmed. A program is written for the PLC which turns on and off outputs based on input conditions and the internal program. PLCs have input lines where sensors are connected to notify events (such as temperature being above/below a certain level, liquid level reached,… etc.), and output lines to signal any reaction to the incoming events (such as start the engine, open or close a specific valve,… etc.). Once a PLC is programmed, it can run repeatedly as needed. PLCs are found inside of machines in industrial environments and can run automatic machines for many years with little human intervention. They are designed for harsh environments. Programmable Logic Controllers are used extensively in process-based industries, they are computer-based solid-state devices that control industrial equipment and processes. Even though PLCs can control system components used in SCADA and DCS systems, they are often the primary components in smaller control systems.
