Product Overview 

The ABB 07KT97F1 Advant Controller 31 is an intelligent decentralised automation system that plays a key role in decentralised automation architectures. The controller can be used as a bus master in a decentralised automation system to efficiently coordinate and manage the operation of the entire system; it can also be used as a slave device (remote processor) to flexibly access a larger automation system; at the same time, it can be used as a stand-alone basic unit to satisfy the automation control needs of relatively small or specific scenarios.

Specifications 

Programme and data storage: with a maximum of 480 kB of user programme space and 256 kB of user data storage space, it can meet the needs of more complex automation control programme writing and large amount of data storage.

Input and output interfaces 

Digital inputs: Equipped with 24 digital inputs with LED display, which can visualise the input status.

Digital outputs: 16 digital transistor outputs, also with LED display, easy to observe the output status.

Mixed digital inputs/outputs: 8 digital inputs/outputs, also with LED displays, for increased flexibility in the use of the interface.

Analogue inputs: 8 individually configurable analogue inputs support a wide range of common signal types such as 0...10 V, 0.... .10 V, 0... .5 V, ±10 V, ±5 V, 0...20 mA, 4... .20 mA, 4... .20 mA, and the differential analogue inputs can also be individually configured as digital inputs, greatly expanding the range of input signals.

Analogue outputs: 4 individually configurable analogue outputs for ±10 V, 0...20 mA, 4... .20 mA, 4... 20 mA.

Additional function modules 

Counter: 2 counters with counting frequency up to 50 kHz, configurable in 7 different operating modes for many automation scenarios requiring precise counting.

Bus interface: 1 CS31 system bus interface for system expansion, easy to connect more devices and modules to build a larger automation system.

Communication Interface: 1 interface for connecting communication module, and 2 serial interfaces COM1 and COM2, of which COM interface can be used as MODBUS interface, and also used for programming and testing functions to meet different communication requirements.

Clock: Built-in real-time clock provides accurate time reference for the system, which plays an important role in some automation control tasks with strict requirements on time sequence.

Status display: There are LEDs for displaying operation status and error messages, which is convenient for operators to quickly understand the working status of the equipment and find and deal with problems in time.

Terminals: Removable screw-type terminals are used for easy wiring and maintenance. The unit can be screwed or clamped to a DIN rail for flexible and easy installation.

Battery Backup: The 07 LE 90 lithium battery can be placed in the battery compartment for storing and backing up user programmes in RAM, storing and backing up data additionally contained in RAM (e.g. status of flags), and backing up the time and date (real-time clock) to ensure that critical data and system configurations are not lost in the event of an abnormal situation, such as a power failure of the system.

Performance Advantages 

High Integration and Flexibility: Rich and flexibly configurable input/output interfaces, as well as the integration of multiple functional modules, make the controller adaptable to diverse automation control scenarios, whether it is simple device control or complex system integration. Users can easily configure the input and output signal types, counter modes, communication interfaces, etc. according to the actual needs, which greatly shortens the project development cycle and improves the efficiency of system construction.

Reliable operation and data protection: With powerful self-diagnostic function, it can not only carry out comprehensive diagnosis on the basic unit itself, but also diagnose the CS31 system bus and the connected modules, detect and warn potential faults in time to ensure stable operation of the system. At the same time, the lithium battery backup mechanism effectively protects the integrity of user programmes and key data in the event of power failure and other emergencies, providing strong support for the continuous and reliable operation of the system.

Efficient communication capability: Equipped with a variety of communication interfaces, especially the MODBUS interface and the interface for connecting communication modules, it is able to carry out efficient data interaction with different types of equipment and systems. Whether it is data transmission with the upper computer or collaborative work with other intelligent devices, a fast and stable communication connection can be achieved, which lays the foundation for the construction of a large-scale, intelligent automation network .

Precautions 

Power supply: The basic unit is powered by a 24 VDC power supply. When connecting to the power supply, make sure that the power supply voltage is stable and meets the requirements, so as to avoid damage to the equipment due to excessive voltage fluctuations or the polarity of the power supply being connected to the opposite side. At the same time, make sure that the power supply capacity of the power supply can meet the power demand of the equipment when it is running at full load.

Installation environment: the equipment should be installed in a dry, well-ventilated, suitable temperature environment, avoid installation in high temperature, humidity, dusty or corrosive gases in the place. The installation location should be far away from strong electromagnetic interference sources, such as large motors, transformers, etc., to prevent electromagnetic interference affecting the normal operation of the equipment.

Wiring operation: In the wiring operation, you need to disconnect the power supply, in strict accordance with the wiring diagram for the correct wiring, to ensure that the wiring is solid, to avoid loosening, short-circuit and other problems. For removable screw terminals, when tightening or loosening the screws, use the appropriate tools to avoid excessive force and damage to the terminals.

Programming and Configuration: When programming and configuring, follow the relevant programming specifications and operation manuals to ensure that the program logic is correct and the configuration parameters are reasonable. When making important configuration changes or downloading programmes, it is recommended to back up the original programme and configuration data in advance to prevent data loss or system failure caused by operational errors.

Comparable Models Supplement 

07 KT 95/07 KT 96: These two models are basic units with reduced performance compared to the 07 KT 97 F1. There may be a reduction in program storage space, data storage space and configuration of some function modules, which is suitable for small projects with relatively simple requirements for automation control functions and more stringent cost control.

07 KT 97 R260 (with ARCNET connection): The basic functions are similar to those of the 07 KT 97 F1, with the addition of an ARCNET connection. This allows this model to better connect and interact with devices that support the ARCNET communication protocol in specific automation network architectures, and is suitable for industrial automation system upgrades or expansion projects that already use the ARCNET network.

07 KT 97 R0220 (with PROFIBUS connection): This model has a PROFIBUS interface, which makes it easy to communicate and work with other devices on the PROFIBUS network in the automation system. For industrial automation lines or control systems based on the PROFIBUS bus, this model can be optimally integrated for efficient data transfer and system integration.

07 KT 97 R0262 (with ARCNET and PROFIBUS interfaces): Integrates both ARCNET and PROFIBUS interfaces for broader communication compatibility. It can interact with devices on both ARCNET and PROFIBUS networks, making it suitable for complex automation networks with multiple communication protocols, and facilitating the interconnection of devices on different network architectures.
