Q: Do we need to upgrade our legacy serial PLCs to connect them to modern cloud systems?

A: No. You can avoid costly hardware replacements by deploying an Industrial Modbus Gateway. These devices help convert old style data like Modbus RTU that uses RS232 or RS485 into new network protocols like Modbus TCP or MQTT. This gives you an easy connection, between your old factory equipment and your main SCADA system or cloud.

Q: What happens to critical machine data if the cellular connection drops at a remote site?

A: In places, with internet data is not lost because of a special way of storing and sending data. This way is called “store-and-forward”. Industrial Cellular Routers and edge computing gateways can cache telemetry data locally during a network outage. Once the cellular link is re-established, the hardware automatically pushes the buffered data to your central server, ensuring your historical data records remain continuous and complete.

Q: How do we secure raw PLC data when transmitting it over cellular networks?

A: PLCs and sensitive industrial control systems should never be exposed directly to the internet that the public uses. Secure data transmission requires encapsulating the traffic within encrypted VPN tunnels (such as IPsec, OpenVPN, or WireGuard) should be set up directly on the hardware. For enterprise-grade security, deployments should also use Private APNs provided by cellular carriers, which keep your traffic separate, from the public network that anyone can use.

Q: Is 5G necessary for our industrial remote monitoring, or is 4G LTE sufficient?

A: For most SCADA telemetry, remote I/O control, and predictive maintenance data, 4G LTE or LPWAN (like LoRa) provides more than enough bandwidth and significantly wider geographic coverage. 5G is typically only required for applications demanding ultra-low latency and massive throughput, such as high-definition machine vision, real-time robotics control, or autonomous guided vehicles (AGVs) on the factory floor.

Q: How do we prevent remote communication downtime if a local cellular carrier experiences an outage?

A: To ensure maximum uptime in unmanned environments, industrial networks use special hardware that has Dual SIM capabilities. Industrial cellular routers and modems equipped with automatic failover can automatically switch to a backup carrier network if the main connection starts to fail or drops out. This redundancy eliminates single points of failure in mission-critical applications like water/wastewater management or smart grids.

Q: Can we deploy standard commercial IT networking equipment in our control cabinets?

A: You should not do this. Commercial IT equipment is not strong enough for Operational Technology environments. Real industrial hardware is purpose-built: fanless cooling, extended temperature ranges (-40°C to 75°C), heavy EMI shielding, and solid DIN-rail mounting. Dropping standard IT switches or routers onto a harsh factory floor usually results in dead hardware and dropped networks down the line.

How does Valtoris manage lead times amidst global supply chain uncertainties?

As a 100% Original Manufacturer with our own assembly lines and strategic component inventory, we guarantee consistent lead times and long-term supply continuity, bypassing typical distributor backlogs.

Are your edge gateways and routers locked into a proprietary Valtoris cloud ecosystem?

Absolutely not. Our hardware is vendor-agnostic, parsing telemetry into standard MQTT, JSON, or Modbus TCP. You can route data directly to AWS, Azure, local SCADA, or private servers.

How do your devices help bridge the gap between OT engineers and IT security policies?

We satisfy both: OT gets rugged, optically isolated hardware, while IT gets enterprise-grade security including Stateful Firewalls, VLANs, and IPsec/OpenVPN tunneling to keep control systems secure.

“Saved my team a massive headache.”

“I usually hate swapping out PLCs because of the protocol nightmares. We tried wiring their gateway to our legacy Modbus RTU drives, expecting a week of debugging. Surprisingly, it mapped straight to our TCP network on the first try.”

Lead SCADA Integrator Top 10 European Solar EPC

“We stopped driving out to reset them.”

“Texas summers were literally melting the commercial routers in our outdoor pump panels. We were doing truck rolls every other week just to reset them. Put the Valtoris units in two years ago and haven’t touched them since.”

Senior Automation Engineer North American Oil & Gas Contractor

“They actually patched our custom issue.”

“The big brands ignored us when we asked for a custom MQTT payload tweak for our infrastructure project. Valtoris got their engineers on a call, looked at our logs, and sent over a custom firmware patch a few days later. That level of direct support is rare.”

Corporate & Procurement FAQ

How does Valtoris manage lead times and hardware availability amidst global supply chain uncertainties?

We run a centralized strategic inventory model instead of distributed channel stock. We guarantee stable lead times and 10-year component availability for all of our standard series through long-term supply contracts for core silicon and dedicated buffer inventory at our partner assembly facilities.

Are your edge gateways and routers locked into a proprietary cloud ecosystem?

Absolutely not. Our philosophy is entirely vendor-agnostic. Our cellular routers and edge gateways parse telemetry into standard MQTT, JSON, or Modbus TCP payloads. You maintain 100% ownership of your data and can route it directly to AWS IoT Core, Microsoft Azure, local Ignition SCADA, or your own private servers.

How do your devices help bridge the gap between factory floor OT engineers and enterprise IT security policies?

There is often friction in bringing the factory floor onto the enterprise network. Our hardware is suitable for both departments. For OT we offer rugged and fanless operation with up to 3000V optical isolation to prevent surges. For IT, we implement enterprise-grade security features including Stateful Firewalls, VLAN segregation, MAC binding, and built-in IPsec tunneling, ensuring control systems remain air-gapped from public vulnerabilities.

What level of engineering support can we expect during a complex network deployment?

Unlike typical distributors, our frontline support is tightly integrated with our R&D team. For standard deployments, our technical specialists provide rapid troubleshooting. For complex network topologies, protocol debugging, or OEM firmware requests, your ticket is escalated directly to our Level 2/Level 3 Application Engineers—the same team that writes our firmware.
