Connecting a remote site to your centralized SCADA system is usually straightforward—until you run out of IP addresses. If you are trying to establish multiple PLCs single public IP remote access, you have likely hit a frustrating roadblock. You have a pump station with 3 different ethernet PLCs, 2 HMIs and an IP camera. But…
Looking for a reliable industrial network broadcast storm fix? The symptoms on the factory floor are impossible to overlook: Your SCADA screen freezes on and off, Modbus TCP connections drop randomly and when you log into the dashboard of your industrial cellular router, the CPU utilization is spiked at 99%. You haven’t added any complex…
Are you struggling with AGV WiFi roaming disconnects? This is an infuriatingly predictable situation in a high-speed warehouse. Your Automated Guided Vehicle (AGV) or Autonomous Mobile Robot (AMR) is effortlessly gliding up the main aisle of the facility. It approaches the boundary between the assembly area and the warehouse—the exact physical midpoint between Access Point…
If you are the person who has to build up an industrial network, you have probably been in this exact situation: Your serial device server works perfectly when connected to one local HMI. The polling is fresh, and the data is sound. But as soon as you connect a second SCADA system from the central…
In industrial automation, few things are as notoriously difficult to troubleshoot as an unstable RS485 network. When a Modbus RTU system works perfectly on a schematic but drops packets, experiences “ghost timeouts,” or completely collapses on the factory floor, the root cause rarely lies in the software—it is almost always a physical layer breakdown. When…
Engineer’s Note: When migrating from legacy industry standards such as the Moxa NPort series, the topology should be carefully planned. This evaluation is written for system integrators and automation engineers tasked with deploying reliable, low-latency SCADA (Modbus/MQTT) systems in modern IT/OT converged environments. Moxa’s NPort 5110 and 5150 have been the default baseline standard for…
Engineer’s Note: Migrating away from legacy industry standards like Sierra Wireless requires careful topology planning. This guide is written for integrators deploying low-to-medium bandwidth SCADA (Modbus/MQTT) systems. High-bandwidth applications should consult their carrier regarding 5G deployment strategies. Surviving the RV50X EOL: What Actually Matters in an Alternative? The industrial networking world is in the midst…
Deploying standard network equipment in a moving bus is a recipe for disaster. Extreme vibration, severe voltage spikes from the alternator, and constant switching between cell towers will destroy consumer-grade routers within weeks. For transit authorities and fleet integrators, maintaining a stable connection is critical—not just for passenger Wi-Fi, but for mission-critical Operational Technology (OT)…
Picture a remote water tank pump station or a pipeline valve located miles away from your central control room. You need to pull real-time Modbus data from the sensors, but there is zero cellular coverage. You have two bad options: deploy an expensive satellite connection, or spend thousands of dollars digging trenches to lay fiber-optic…
Imagine deploying 500 soil sensors across a massive agricultural facility. If you choose the wrong connectivity protocol, you will either bankrupt your project with monthly SIM card data fees, or spend thousands on labor just to replace dead batteries every few months. This is where the LoRa vs 4G LTE decision dictates the success or…
