Put the question into a real site situation first. An industrial router is already installed in the cabinet, and the site now needs a protocol-conversion program. Because the router supports Docker, placing the container there seems efficient: one less device, one less power connection, and less cabling. The answer changes quickly if the workload is a local database, video analytics, or an application that writes logs continuously. The real question is not only whether the co

Introduction: Why Is Modbus Still Widely Used? Modbus has been used in industrial communication since Modicon introduced it in 1979. Its request/response model remains useful for reading measurements, device status and control registers in energy, water, process industries and manufacturing. Its continued use is best explained by installed equipment, accessible specifications and straightforward implementation, rather than by unsupported market-share or device-count estimates

Introduction: The Communication Backbone of the Smart Grid Era A substation has more than one communication problem. Protection devices must exchange time-sensitive information inside a designed station network, while operators also need measurements, alarms, and authorized access beyond the station. These paths have different timing, availability, and security requirements. An industrial router may serve the external path; it does not turn a remote WAN into a protection netw

A router can have a fast CPU and still fall short when encryption, cellular uplink, storage writes or heat becomes the bottleneck. Conversely, a modest processor may be sufficient for a gateway that forwards a few sensor messages. Select the platform by the complete workload and interfaces, rather than treating Arm, x86 or RISC-V as a performance ranking. A router contains several computing parts. The application processor or system-on-chip (SoC) runs the operating system and
