MOTOR CONTROL WITH PARALLEL CONDITION MONITORING

Turck's compact TBEN-S-2COM I/O module transfers process and status data over the same Ethernet cable

Vibrations have proven to be a reliable indicator of wear and imminent faults, especially for motors. Different frequency patterns provide information about anomalies such as imbalance or bearing damage. Systematic condition monitoring combines sensor signals, data evaluation and targeted communication to help detect these issues early on. Turck's compact TBEN-S-2COM I/O module enables status and control data to be transferred simultaneously in Industrial Ethernet networks. Users can efficiently use existing infrastructures with no need to pay premium prices for additional hardware.

Your Benefits

  • Greater machine availability thanks to timely warnings about imminent damage
  • No additional wiring due to communication via existing Ethernet cables
  • Low-priority parallel querying process to prevent interaction with the machine control
  • Decentralized integration of motors with a serial interface in Industrial Ethernet networks

    Vibrations can be an indication of wear or faults in motors

    Turck’s I/O module TBEN-S2-2COM supports three different Ethernet protocols

    In addition to vibration, the QM30 sensor (IP67) also detects temperature changes

A vibration sensor at the heart of the machine

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

Data transfer with a different priority

In addition to communicating with a vibration sensor, the compact TBEN-S2-2COM 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.

Advanced services in the cloud

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 visualize status data as well as offering 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.
