Recently, TSC industrial Ethernet equipment once again contributed to the construction of a large-scale national steel system, building a highly reliable industrial network for the energy management system of a well-known domestic steel plant.
The energy management system's transmission network adopts an access-aggregation-core architecture. The core layer consists of two core switches, achieving core network redundancy through hot standby. The core layer devices and the aggregation layer are interconnected via 1000M fiber optic cables. The aggregation layer consists of eight devices forming a 1000M industrial ring network to achieve millisecond-level self-healing of backbone link failures. Access layers connect to each other, and access layers connect to the aggregation layer via 1000M uplinks, using a star topology. The network topology is shown in the diagram below.
Based on the site environment and requirements of this energy management system network project, industrial Ethernet switches manufactured by TSC were specifically selected. Details are as follows:
1. Industrial ring backbone network
The backbone mainly consists of a gigabit ring network built by eight aggregation switches. Access layer switches are connected to the backbone via a star network.
2. Terminal access layer interconnection
For terminal access layer interconnection, 100M fiber optic cables or 100Base-TX cascades are used. Downstream PLCs and terminal devices are connected via 100M electrical ports.
The advantages of implementing industrial Ethernet switches in this energy management system network: Based on the analysis of the existing network of this energy management system and the guarantee of stability, redundancy and reliability, industrial Ethernet switches are adopted in the design to meet the network architecture of this network equipment.
The advantages of industrial Ethernet in this energy management system network are explained below:
1. Overall Network Architecture:
The overall backbone network is constructed as a 1000M redundant ring network according to the needs of actual applications. The redundant ring network topology is a common industrial network topology, which can achieve millisecond-level convergence of network faults, thereby ensuring reliable data transmission.
2. Requirements for the steel industry:
In the steel industry, Ethernet transmission media and equipment are required to have strong protection levels and anti-interference capabilities. Industrial-grade Ethernet equipment demonstrates its advantages in terms of support for harsh environments, stability assurance, and equipment warranty period.
