Cloud Compatible
The ControlByWeb Cloud streamlines monitoring, control, and data logging. It provides access to your controller but keeps logic on the device, so you are not dependent on network connectivity. Get the best of both worlds with our reliable platform.
The Benefits of WiFi in IIoT
Flexible
WiFi-enabled PLCs are often used when a hardwired Ethernet connection isn’t feasible. It may be impossible to pull or install wire in an existing structure, for example.
Cost-Saving
With WiFi, integrators can avoid the expense of burying a line, channeling Ethernet cables, and installing other physical components.
Frictionless Installation
Our WiFi-enabled PLCs can be assigned network credentials through the built-in interface. Then, all the module needs is power and you’re ready to go.
Extended I/O
WiFi capability allows PLCs to be physically distant from the rest of the system, bridging the gap between where the data is collected and where it’s utilized.

- Email/Text alerts
- Custom Logic – No programming required
- Built-in web server
- Rugged, DIN rail or wall mount enclosure

Application Spotlight: WiFi Refrigeration Monitoring
Industrial refrigerators and freezers house thousands of dollars in perishable goods. Even a short fluctuation in temperature caused by fan failure, an unsealed door, or a power outage may be enough to spoil the contents. A restaurant manager’s whole week could be ruined by one faulty cooler—and it isn’t just the food and beverage industry that utilizes cold storage. Most vaccines, certain chemicals, and even mylar film prints require careful temperature control.
WiFi-enabled PLCs allow for precise, wireless monitoring of refrigeration units. They can measure ambient temperature, track how long walk-in doors are left open, verify that fans are operating, and send timely notifications when temperatures fluctuate too far from the accepted threshold for too long.
The ControlByWeb PLC featured in this application is the purpose-built FridgeAlert™, but other WiFi-enabled PLCs like the X-410W™ offer a flexible temperature-monitoring solution.
