SONCEBOZ controller, German SONCEBOZ model, SONCEBOZ price

The SONCEBOZ controller is an electronic system for digital arithmetic operations, specifically designed for industrial environments. It uses a programmable memory to execute instructions for stored logic operations, sequential control, timing, counting, and arithmetic operations. It controls various types of mechanical equipment or production processes through digital or analog input (I) and output (O) interfaces. The programmable controller was developed based on electrical control technology and computer technology, and has gradually evolved into a new type of industrial control device that integrates automation technology, computer technology, and communication technology with a microprocessor at its core. PLC has been widely used in the automatic control of various production machinery and processes, becoming one of the most important, widespread, and frequently applied industrial control devices. It is recognized as one of the three pillars of modern industrial automation (PLC, robotics, CAD/CAM).

SONCEBOZ Controller Classification

1) Non-networked door controller: A single unit manages one door. It cannot be controlled via PC software, nor can records be viewed; control is performed directly through the controller. Features include low cost and simple installation and maintenance. However, records cannot be viewed. It is unsuitable for locations with more than 50 people or high personnel turnover (frequent hiring and resignations), and also unsuitable for projects with more than 5 doors. 2) Networked door controller: An access control type that communicates with a computer, allowing direct management via software, including card and event control. Benefits include convenient management, centralized control, record viewing, and data analysis for other purposes. Features include higher cost and increased installation and maintenance difficulty, but simple training and value-added services such as attendance tracking. Suitable for projects with many people, high mobility, and many doors. 3) TCP/IP network door controller: Also known as Ethernet networked access control, this is a networkable access control system that connects the computer and controller via network cables. In addition to all the advantages of networked access control, it offers faster speed, simpler installation, greater networking capacity, and cross-regional or cross-city networking. However, equipment costs are high, and computer networking knowledge is required. Suitable for large projects, locations with many people, speed-sensitive applications, and cross-regional installations.

SONCEBOZ Controller Structure

1) Central Processing Unit (CPU): The Central Processing Unit (CPU) is the control hub of the PLC, serving as its core and neural center. Each PLC system has at least one CPU. It receives and stores user programs and data entered from the programmer according to the functions assigned by the PLC system program; checks the status of the power supply, memory, I/O, and watchdog timer, and diagnoses syntax errors in the user program. When the PLC is running, it first scans and receives the status and data from field input devices, storing them in the I/O image area. It then reads the user program line by line from the user program memory, executes logical or arithmetic operations as per the instructions after decoding, and sends the results to the I/O image area or data registers. After all user programs are executed, the output states from the I/O image area or data in the output registers are transmitted to the corresponding output devices. This cycle continues until operation stops. To further improve PLC reliability, large PLC systems may use dual CPU units for redundancy or triple CPU voting systems. Thus, even if one CPU fails, the entire system continues to operate normally. CPU speed and memory capacity are critical parameters for PLC, determining its operating speed, I/O quantity, and software capacity, thereby limiting the control scale. 2) Memory: System program memory stores system software; user program memory stores PLC user applications; data memory stores intermediate states and information during PLC program execution, equivalent to PC RAM. 3) Input/Output Interfaces (I/O modules): The interface between PLC and electrical circuits is achieved through the input/output section (I/O). I/O modules integrate PLC I/O circuits; input latches reflect input signal states, and output points reflect output latch states. Input modules convert electrical signals into digital signals for the PLC system, while output modules do the reverse. I/O includes modules such as discrete input (DI), discrete output (DO), analog input (AI), and analog output (AO). 4) Communication Interfaces: The main function of communication interfaces is to enable data exchange (communication) between PLC and external devices. Communication interfaces come in various forms, with basic standard serial interfaces including UBS, RS-232, and RS-422/RS-485. Connections can be made via multi-core cables, twisted pairs, coaxial cables, or optical fibers. 5) Power Supply: The PLC power supply provides operating power for PLC circuits and plays a crucial role in the entire system. A good, reliable power supply system is the most basic guarantee for PLC. Generally, if AC voltage fluctuation is within +10% (+15%), the PLC can be directly connected to the AC mains without additional measures. Power input types include: AC power (220VAC or 110VAC) and DC power (commonly 24VDC).

SONCEBOZ Controller Features

1) High reliability and strong anti-interference capability: PLC replaces a large number of intermediate relays and time relays with software, leaving only a small amount of hardware related to inputs and outputs. Wiring can be reduced to 1/10~1/100 of that in relay control systems, significantly reducing failures caused by poor contact. High reliability is a key performance metric for electrical control equipment. PLC utilizes modern large-scale integrated circuit technology, strict manufacturing processes, and advanced internal anti-interference techniques, resulting in high reliability. For example, the mean time between failures for Mitsubishi's F series PLC is as high as 30 hours. Some PLC systems using redundant CPU have even longer mean times between failures. Regarding external PLC circuitry, using PLC for control systems reduces electrical wiring and switch contacts to a few hundredth or even thousandth of those in relay-contactor systems of comparable scale, greatly lowering failure rates. Additionally, PLC features hardware fault self-diagnosis, issuing alarm information promptly upon failure. In application software, users can incorporate peripheral device fault self-diagnosis routines, providing fault self-diagnosis protection for circuits and equipment other than the PLC. Thus, the entire system achieves extremely high reliability. 2) Complete hardware suite, comprehensive functions, and strong applicability: PLC has evolved into serialized products of various sizes (large, medium, and small), standardized, serialized, and modularized, with a wide variety of hardware devices available for user selection. Users can flexibly and conveniently configure systems to create systems of different functions and scales. PLC installation and wiring are also convenient, typically using terminal blocks for external connections [3]. PLC has strong load-driving capability, directly driving general solenoid valves and AC contactors, suitable for industrial control applications of various scales. In addition to logic processing, modern PLC mostly possesses comprehensive data arithmetic capabilities, suitable for various digital control fields. Numerous PLC function units have emerged, allowing PLC to penetrate various industrial controls such as position control, temperature control, and CNC. Enhanced PLC communication capabilities and developments in human-machine interface technology make it very easy to compose various control systems using PLC. 3) Easy to learn and use, popular among engineering technicians: As a general-purpose industrial control computer, PLC is industrial control equipment oriented toward industrial and mining enterprises. Its interfaces are easy to use, and its programming languages are readily accepted by engineering technicians. Ladder diagram language symbols and expressions are quite similar to relay circuit diagrams; only a few PLC discrete logic control instructions are needed to conveniently implement relay circuit functions. This opens a convenient door for those unfamiliar with electronic circuits, computer principles, and assembly language to use computers for industrial control. 4) Easy to modify: System design, installation, and commissioning workloads are small, maintenance is convenient, and modifications are easy. PLC ladder programs generally adopt sequential control design methods. This programming method is regular and easy to master. For complex control systems, ladder diagram design time is much less than that for designing relay system circuit diagrams. PLC uses stored logic instead of wired logic, greatly reducing external wiring of control equipment, significantly shortening the design and construction cycle of control systems, and making maintenance easier. More importantly, it enables changing production processes by modifying programs on the same equipment. This is very suitable for multi-variety, small-batch production scenarios. 5) Small size, light weight, and low energy consumption: Taking ultra-small PLC as an example, recently produced models have base dimensions smaller than 100mm, equivalent to only a few relays, thus reducing cabinet volume to 1/2~1/10 of the original. Its weight is less than 150g, and power consumption is only a few watts. Due to its small size, it is easily installed inside machinery, making it an ideal controller for mechatronics integration.
