Improve Reliability and Performance for Refineries
with Full Gigabit Redundancy
Oil refineries are large scale plants where many units are operated continuously for long periods of time. Producing a variety of petroleum products at high capacity while improving environmental and safety regulations is crucial to a refinery's success. Distributed Control Systems (DCS) are deployed in complex oil refining processes to connect the entire system of controllers for communication and monitoring. A sudden breakdown in the DCS system can be extremely costly for the production line, so the process control system must be designed with full redundancy to achieve high data availability and optimal manufacturing productivity. In order to ensure high data availability and real-time transmission, wider network bandwidth is a major concern for system design. DCS networks that extend across the entire plant play an integral part in enhancing the safety of a plant's operating environment.
Industrial Ethernet is adopted as the main communication network for the entire DCS system due to its interoperability, flexibility, and cost effectiveness.
Dual redundant networks are designed for all critical nodes such as HMI/SCADA systems, controllers, and remote I/O connections. One redundant fiber optic network is formed to connect multiple operating units and another backup network is built to connect redundant controllers with fault tolerant devices in the field.
A high-bandwidth Ethernet network for transferring high volumes of data in real-time, enabling refinery operators to respond quickly to emergency situations.
Dual redundant networks can be built with Moxa's full Gigabit Ethernet switches, which support up to 9 Gigabit ports with 5 fiber optic ports.
Moxa's industrial Ethernet switching solutions support Turbo Ring redundant technology (recovery time < 20 ms).
Moxa oil refining network solutions feature high MTBF ratings with fan-less design, high-EMI noise immunity, redundant power supplies, and fiber optic support. All of these features allow long term stable operation in a refinery plant.
Depending on your system requirements, you may choose from among the EDS-G509 with 9 Gigabit ports or the EDS-510A with 2 Gigabit ports for redundant ring and 1 Gigabit port for uplink.
