Transfer Process and Status Data Over the Same Ethernet Cable

Effective monitoring requires sensors to connect seamlessly with a higher-level system such as the cloud. To detect vibration and temperature values, its QM30VT2 sensors can each send the measurements to an I/O module. In the subsequent evaluation stage, speed and acceleration data is used to detect errors, perform diagnostics or make predictions.

In addition to communicating with a vibration sensor, the compact TBENS2- 2COM multiprotocol I/O module can transfer process data from the system control to the motor via various communication standards, including RS485 (multipoint) and RS232 (point-to-point). The module also has inputs for four additional binary signals.

Industrial Ethernet communication is established via multiprotocol technology. The process data can be transferred to the control system at the same time as to edge gateways, HMIs, control systems or cloud applications. This feature ensures that motor control functions as normal in the PLC while vibration data is evaluated at a different level. Vibration data is transferred with a lower priority than motor control data, ensuring reliable communication of both data flows on the same Ethernet cable.

Edge controllers, such as Turck's HMI/ PLC TX700, can pre-process the measured values from the vibration sensors or directly transfer this data, either to local systems or to the cloud, via protocols such as MQTT or OPC-UA. Individually configured cloud dashboards visualise status data and offer various notification options for when a threshold is exceeded. Maintenance engineers, therefore, receive information about irregularities immediately and can access condition monitoring data on different end devices.
