One platform for future-proof modular networks

Industrial networks continue to evolve, with more and more devices being connected. As a result, connectivity requirements for industrial applications are also increasing. Achieving a flexible, scalable and reliable network capable of handling the growth and diversity of industrial networks is a major challenge today. Therefore, companies look for a versatile solution that is easy to maintain to ensure smooth operation while keeping costs down. The MDS-G4000 series modular switches, which offer a mix-and-match Gigabit platform, are ideal for such flexible network applications.

Moxa's MDS-G4000 series of modular switches support up to 12/20/28 Gigabit ports. This mix-and-match Gigabit platform provides an adaptive industrial networking solution, meeting constantly changing requirements in terms of the number and type of interfaces needed. “These products support a wide range of media interface modules to enable any combination. Each module is equipped with four ports to allow a maximum number of combinations: one platform, which can be easily adapted to any need,” says Karel Mus, general manager of distributor Technolec. “The modular concept ensures minimal downtime. It takes only a few seconds to replace interface or power supply modules, without having to switch off the switch.” These switches are used in a wide variety of applications, including mining control systems, traffic through tunnels, gas pipelines or for merging Ethernet-based substations.

These modular switches are deployed in substations, among others.

New standards in substations

Traditional substations use hard-wired links between devices that perform serial connections at a relatively low speed via copper wires. The intelligent electronic devices in today's modern substations are designed around the IEC 61850 standard and can be connected to a high-speed Ethernet bus, making it easier to implement management, maintenance and control through a centralised power SCADA system.

The solution of Moxa

To anticipate the large number of intelligent electronic devices (IED) in modern substations, it is best to install modular switches type MDS-G4012 from Moxa at the base of the network infrastructure. These modular switches meet the requirements of IEC 61850-3 and IEEE 1613 standards, making them highly efficient and reliable for use in such applications. An intelligent QoS control ensures that critical data is forwarded on a priority basis, and the robust cabinet of the system ensures reliable and smooth communication in applications where operation can be greatly affected by the environment. This ensures error-free operation without interruptions. The isolated power supply modules can be replaced on site without having to switch off, ensuring that substation operation is never interrupted.

Offering a mix-and-match Gigabit platform, the MDS-G4000 series modular switches are ideal for such flexible networking applications.

Armed against cyber attacks

With the increasing number of cyber attacks on critical infrastructure, it is fundamental to better protect network devices in power applications. Moreover, in such applications, one must also be able to rely on continuous updates from the vendor to remain armed against cyber attacks. “Moxa has equipped the modular switches of the MDS-G4012 series with all the features, which ensure that networks are more secure. Unauthorised persons are also denied access. The manufacturer also has a team of cybersecurity specialists who can respond quickly in case of any cyber attacks,” Mus explains. “As a distributor, we advise customers on choosing the right products. We always look for the most efficient and qualitative solution for each issue. Moxa's MDS-G4000 series modular switches are ideal for secure interconnection of devices in flexible industrial network applications.”
