Enhance System Uptime with Reliable, Scalable Networks

The shift towards Industry 4.0 and the Industrial Internet of Things (IIoT) has heightened the need for network nodes to facilitate connected systems. While some network nodes can utilize unmanaged switches with basic management functions to reduce network complexity and administrative workload, other scenarios may necessitate managed switches, which continue to be crucial in extensive integrated networks. It is imperative that your managed switches are more intelligent and adaptable than ever before to accommodate new changes and ensure efficient data delivery. In this piece, we explore three fundamental criteria to assist you in selecting a suitable managed switch for modern automation.

Essential Considerations for Selecting Managed Ethernet Switches

Straightforward Usage, Simple Operation

Effective usability is crucial for any networking solution. This is particularly vital for industrial automation due to the multitude of network nodes present in a single industrial network. From installation to day-to-day operation and upkeep, the following features of managed switches can aid in managing tasks efficiently.

Diverse Mounting Solutions Simplify Installation

Each node may have distinct requirements based on its installation location. Having various mounting solutions can streamline the installation process.

Visualizing Network Status

Monitoring the status of network nodes is one of the numerous tasks engineers have to balance. Opting for managed switches with user-friendly interfaces enables swift status checks and seamless modifications.

Effortless Hot-swappable Design for Maintenance

Regular device maintenance is inevitable. Selecting a modular managed switch allows you to hot-swap a power or line module during routine maintenance without disrupting overall operations.

When opting for a managed switch, future network expansion should be considered. Instead of seeking a compact, high port-density solution, it is advisable to opt for a modular design to save time when installing additional systems as needed. Additionally, the geographical location of your interconnected systems should be taken into account. While networking systems within a single factory may pose no issue, extending the project across multiple factories or facilities in diverse locations warrants managed switches that support optical-fiber transmissions for dependable data transfer over extensive distances. Environmental constraints can pose challenges in network connectivity. While wired cabling options have advantages, wireless networks may need to be considered as an alternative for hard-to-wire applications.

Interconnecting industrial systems significantly elevates network complexity and can impact daily operations. A single point of failure can lead to network downtime, risking the loss or tampering of critical data. To avert network node failures, your managed switches should incorporate redundancy mechanisms and security features.

Redundancy Mechanisms

Network redundancy is a sophisticated feature present in managed switches to prevent critical data loss in the event of a network node failure. Enabling a redundant backup path can circumvent the failed node and restore data transmission swiftly.

Security Features

With the surge in network nodes and connectivity, there is an increased risk of unauthorized access and vulnerabilities. Security aspects should not be underestimated. It is recommended to opt for networking devices with security functionalities compliant with the IEC 62443 standard to safeguard your network node against unwanted access. For added assurance, selecting a vendor with a dedicated cybersecurity response team can protect networking devices from potential vulnerabilities.

Applying the aforementioned key criteria to evaluate managed switch options can guide you towards selecting the most appropriate solution for automating your industrial network. In response to evolving network demands, Moxa has introduced a new series of industrial managed Ethernet switches—the MDS-G4000 Series—featuring a scalable modular design that offers cost-effective usability, security, and network availability across various industrial applications.
