Three Easy Ways to Access Your Data

Open REST API icon

Open REST API

Our REST API uses simple, well understood, and battle-tested HTTP Get requests to poll data, access log files, and control relay states from custom software, or from popular industrial platforms such as Ignition, TIA Portal, and more. This is quickly becoming the integration method of choice for many software engineers.

Open Industrial Protocols

Open Industrial Protocols

We prioritize compatibility and ease of use by incorporating MQTT, Modbus TCP/IP, and SNMP into our edge controllers. This makes integration with virtually any industrial control system, SCADA, or IoT platform easy. These open protocols are industrial standards and have broad compatibility.

ControlByWeb Cloud Icon

ControlByWeb Cloud API

Our optional cloud service makes remote access to data much easier with a simple UI and an open API. Build apps and interfaces that pull data from our devices via our cloud. Poll devices and send relay commands for full I/O access from anywhere.

This ControlByWeb case study highlights IVI system designer Thad Failor, who built an all-in-one control panel that uses ControlByWeb modules communicating with their software via our Rest API, using HTTP GET requests. Our hardware allows the control system to monitor and control large scale HVAC equipment. Thad said that “the whole system together gives the storage manager the tools they need to be able to successfully store the product at the optimal conditions.”

Our edge controllers play a key role in agricultural temperature and humidity control. In this case, they’re connected to finely tuned equipment to monitor and control temperature, humidity, airflow, and CO2. They’re doing what they do best—monitoring sensor data, sending it back to the control software. The software processes the data and sends command back to ControlByWeb I/O modules that, in turn, control fans, lighting, HVAC units, humidifiers, and motorized doors and vents.

Cellular + Cloud

Our cell-enabled edge controllers increase installation flexibility dramatically, giving more options for integrated systems no matter where they’re located or how dispersed they may be. Each cell device also comes with WiFi and Ethernet, so they can failover to either one-adding an uncommon layer of reliability to remote applications.

The ControlByWeb Cloud provides remote access to each of our cellular devices at no additional cost (included in the data plan). Enjoy dashboards, reports, data logging, and more.
