Basic Information

Model identification: GJR5253100R0220 07KT98 is the basic unit in the ABB Advant Controller 31 series. This model number is an important identifier used by ABB for product identification and categorisation, helping the user to pinpoint the controller amongst the many products available.

Country of origin: Usually from ABB's plants in Europe, e.g. Sweden. These regions have a sophisticated industrial manufacturing environment and strict quality control standards to ensure high quality and reliability.

Physical characteristics: Measures approximately 25.4 cm long, 10.2 cm wide, 15.2 cm high and weighs approximately 0.9 kg. This compact design allows it to be easily mounted in a control cabinet, saving space and allowing for easy layout and integration in industrial sites.

Performance Characteristics

Processing power:

Computing speed: The internal processor has a highly efficient computing speed that enables it to quickly process a variety of complex control algorithms and logic operations. In industrial environments, it can process the input and output signals of multiple devices in real time, such as processing signals from different sensors at the same time and rapidly outputting control instructions to ensure the real-time responsiveness of the system.

Multi-tasking: It supports multi-tasking function and can run multiple control programmes or task threads at the same time. This makes it possible to simultaneously handle multiple tasks such as device monitoring, data acquisition, communication management, etc. in a single system without significant performance bottlenecks.

Storage Performance:

Programme Memory: With 1MB of programme memory, this capacity can meet the needs of writing most industrial automation control programmes. Users can use this memory to write complex control logic, including sequential control, conditional judgement, loop structure, etc., in order to achieve precise control of various industrial equipment and processes.

Data Memory: Data memory is used to store temporary data, equipment parameters, historical records and other information during system operation. Adequate data memory ensures that the system can effectively manage and utilise such data during long periods of operation, for example, storing real-time data collected by sensors for subsequent analysis and processing.

Communication features:

Types of communication interfaces: A variety of communication interfaces are available, such as Ethernet and RS-232 interfaces. The Ethernet interface provides a high-speed and stable data transmission channel, which is suitable for remote communication and data interaction with the host computer, other PLCs or remote monitoring systems, while the RS-232 interface is mainly used for connecting some local devices, such as specific sensors, actuators, or older devices, which enhances the compatibility of the devices.

Communication protocol support: It supports a variety of industry-standard communication protocols, such as CS31 and Modbus. Through these protocols, it can seamlessly interface with protocol-compliant devices made by different manufacturers to achieve data sharing and collaborative work. For example, in an automated factory, it can communicate with smart meters that support Modbus protocol to obtain energy consumption data.

Functional Features

Input and output functions:

Digital I/O:

Input channels: It has 24 digital input channels, and these channels can be connected to various digital sensors, such as push buttons, limit switches, photoelectric switches, and so on. When the status of these sensors changes, the controller can detect the change of the input signal in time, which can be used for equipment status monitoring, position detection and other application scenarios.

Output Channel: It contains 16 digital output channels, which are mainly used to drive digital output devices, such as relays, indicator lights, solenoid valves and so on. Through these output channels, the controller can realise the control of external devices, such as starting or stopping the motor, lighting up or extinguishing the indicator lamps, and so on.

Combination channel: There are 8 digital combination input and output channels, users can flexibly configure whether these channels are used as inputs or outputs according to the actual demand, which increases the flexibility and expandability of the system.

Analogue I/O:

Input channels: 8 analogue input channels are provided, capable of receiving continuous signals from analogue sensors, such as temperature sensors (outputting 4 - 20mA current signals or 0 - 10V voltage signals), pressure sensors, flow sensors and so on. These channels can convert physical quantities into digital quantities for data processing and control.

Output channels: There are 4 analogue output channels, which can output continuous analogue signals for controlling devices requiring analogue inputs, such as frequency converters (to regulate the speed of motors), regulating valves (to control the flow rate or pressure), etc., so as to achieve precise control of physical quantities on industrial sites.

Expandability: As a basic unit, it has good expandability. Users can add expansion modules to increase the number of input and output points, communication interfaces or other special functions. For example, when you need to expand more digital or analogue input and output channels, you can add the corresponding I/O expansion module; if you need to support other special communication protocols or increase the number of communication interfaces, you can also add communication expansion modules to meet the demand. This scalability allows the system to be flexibly adjusted with the development of industrial production and process changes.

Reliability and Stability:

Hardware Reliability: Manufactured with high-quality electronic components, these components undergo rigorous screening and testing to ensure that they work properly in harsh industrial environments. For example, under high temperature, high humidity, strong electromagnetic interference and other conditions, it can still maintain stable performance, reducing the probability of system failure due to environmental factors. The housing design also takes into account the protection and heat dissipation factors, effectively protecting the internal circuitry.

Software stability: The built-in operating system and control software have powerful error detection and recovery mechanisms. If disturbances or errors are encountered during programme operation, the system is able to automatically diagnose and attempt to restore normal operation, reducing the impact on the control process. At the same time, ABB will regularly update the software, users can easily upgrade the software to improve the performance and safety of the system.

Programming Flexibility: Multiple programming languages are supported, such as ladder diagrams, function block diagrams, instruction lists and sequential function diagrams.

Ladder Diagram: The ladder diagram programming language is intuitive and easy to understand, similar to a traditional electrical control schematic. For engineers who are familiar with electrical control, ladder diagrams can be used to easily construct control logic and represent logical relationships through simple graphical symbols (e.g., normally open contacts, normally closed contacts, coils, etc.) and connecting lines, which are easy to understand and maintain.

Function Block Diagram: Function Block Diagram focuses on the combination and invocation of function modules and is suitable for implementing complex control algorithms. Users can combine different function modules (e.g. PID control module, arithmetic operation module, etc.) together to quickly build a complex control system and improve programming efficiency.

Instruction list: Instruction list is similar to assembly language, providing a programming way to operate directly on processor instructions. For users who have higher requirements on the efficiency and details of program execution, the instruction list can control the execution process of the program in a finer way.

Sequential Function Chart: Sequential Function Chart is mainly used to describe the sequential logic of a control system, which clearly shows the operation flow of the system by dividing the control process into several sequential execution steps. This programming language is particularly suitable for industrial application scenarios where sequential control is the main focus, such as the process control of automated production lines.
