Sending sensor data directly into the IoT through MQTT

Comtrol has supports MQTT integration in its IO-Link family of products alongside embedded support for the OPC-UA protocol to allows sensor data to be delivered directly into the Internet of Things (ioT) and SCADA control systems.

Sensor control and monitoring have traditionally been achieved by hardwiring I/O data to PLC’s, or connecting to network blocks, which then communicate with a PLC. This method traps sensor data needed for predictive maintenance and condition monitoring.

Comtrol has developed a method giving factories and machine builders ultimate flexibility for their applications. Sensor data can now be sent directly to an OPC Client, SCADA software or IoT system through OPC-UA or MQTT database connections integrated on Comtrol’s IO-Link block. Users can also simultaneously control devices from the PLC or another controller using Ethernet/IP, Profinet or Modbus TCP.

“Comtrol is excited to be able to provide direct sensor connections to IOT systems through our IO-Link Master. Customers now have a choice to bypass the PLC or work together with the PLC system. Comtrol’s IO-Link technology with OPC UA and MQTT gives users access to complete sensor data without the hardware and software costs associated with PLC systems,” says Bradford Beale, President of Comtrol.
Comtrol sells RocketLinx industrial grade Ethernet and Power over Ethernet switches, IO-Link Master industrial gateways, DeviceMaster Ethernet device servers and gateways and RocketPort multiport serial cards.
