Plant/Shop-Scale Cabling Systems
Plant/Shop-Scale Cabling Systems are designed for data transmission and communication within a plant/shop and include Level 1 networks and industrial networks.
ПSuch cabling systems support the following applications: voice transmission, data transmission, transmission of digital and analog video signals; automation systems for buildings and structures, as well as automation systems for industrial and electrical applications; energy control and monitoring systems; fire safety systems; security and access control systems; heating, ventilation and air conditioning systems.
Plant/Shop-Scale Cabling Systems can be as follows:
- multifunctional telecommunication systems, which can be fiber optic systems, modular cabling systems or structured cabling systems.
- industrial networks
Fiber optic and modular-type multifunctional telecommunication systems are designed to meet the requirements specified for backbone cabling systems.
Structured cabling systems are designed to meet the requirements specified for cabling systems intended for office buildings.
Industrial networks are designed to enable the physical and logical connection between instruments, actuators and PLCs or industrial computers for the data to be accessible by the corporate information system of an enterprise.
An industrial network provides the basis for building distributed data acquisition and management systems. Industrial networks can employ various data transmission media, including copper and fiber optic lines and wireless technologies.
Network infrastructure components include:
- Field Level Networks
Field level networks are designed to collect data coming from field instruments, actuators and their secondary instruments, control panels, circuit breakers, power protection terminals and remote drive control units.
- Level 1 (PLC) Networks (PROFIBUS, MODBUS)
Level 1 Networks ensure data transmission via PROFIBUS (MODBUS) between controllers, data acquisition and transmission devices, local panels, position transducers, drive control units, etc. They also ensure data to be transmitted to the next level.
- Level 2 (Process Control) Networks (Ethernet)
The main functions of Level 2 process control systems include process data registration, storage, and management. Level 2 is based on real-time database. Such data can be used to register, store and visualize alarms and process statuses and to control the process with the help of a mathematical model. Level 2 data are accessible by a great number of users from the operational level.
- Level 3 (Production Control) Networks (Ethernet)
Level 3 is designed for integration of process control systems and the production control system. In certain cases, depending on the company size an even higher level (Level 4) can be implemented to ensure integration with the top management, who can be based in different overseas locations.
