Network solutions for refineries and chemical plants

There are a large number of intelligent devices in refineries and chemical plants, many of which must maintain uninterrupted operation for a long time. DCS，MES，SIS and security systems connect various controllers and monitors through Ethernet networks to manage and monitor the production and performance of the factory.

Topology Map

system requirements

·Highly stable and flexible Ethernet network
·Provide redundant networks for various systems, controllers, and field devices to achieve fast network self-healing
·Sufficient bandwidth to meet the needs of video surveillance services
·When DCS, SIS, MES systems fail, the network system needs to provide the ability to control the fault range within a single domain
·The communication system needs to provide the ability to filter data and determine the legitimacy of access devices
·Communication equipment needs to have good electromagnetic compatibility and provide redundant power input
·Low network data transmission delay and small delay jitter
·It is necessary to provide a secure access mechanism for communication devices to avoid human sabotage

Reason for selection

·Dongtu high-performance network management industrial Ethernet switch provides reliable network connection, excellent network performance, and ultra long fault free working time to meet 7X24 hour continuous operation requirements
·Support STP/RSTP, DT Ring, IEC62439-6/DRP and other network redundancy functions, providing fast network fault self-healing capability
·Backbone network provides 1000Mb high bandwidth guarantee, ensuring unobstructed data transmission, supporting giant frame transmission, and improving bandwidth utilization
·Support port fault isolation, traffic anomaly monitoring and alarm, loop back detection, control the fault range in system abnormal states, and provide clear and effective alarm information for fault recovery.
·Support TCP/UDP packet filtering, MAC address binding, and achieve a pure communication network that only retains system business data to prevent unauthorized devices from accessing.
·Support SSH, SSL, and SNPv3 to ensure secure network system management.
·EMC level 4, industrial grade design, wide temperature range of -40~85 ℃, providing independent dual redundant protection power input
·Data delay less than 5 μ m, delay jitter less than 1 μ m
