Sensor Diagnostics in Harsh Environments

Manufacturers and industrial operators can now access more detailed sensor diagnostics in harsh operating environments.

The IP67-rated, Allen-Bradley ArmorBlock IO-Link master from Rockwell Automation builds on the company’s IO-Link portfolio with event and process timestamping capabilities for on-machine applications.

The new IO-Link master stores up to 40 timestamps of sensor events on each channel. This event history can help users track changes and more easily diagnose issues. Input timestamps of all sensor data also can be sent to the controller upon a change of state. These and other diagnostics available through the device can reduce issue-resolution time by as much as 90 percent, improve preventive maintenance and optimize overall system performance.

“The ArmorBlock IO-Link master with IO-Link-enabled sensors can aid end users in creating smarter operations without a complete overhaul,” said Kevin Gagliostro, product manager, Rockwell Automation. “They can deploy the technology to monitor temperature, and margin-indication or proximity parameters in critical processes. They can also target problem areas where better diagnostics are needed to remedy issues.”

While the new ArmorBlock IO-Link master is ruggedized for use in harsh applications, the Rockwell Automation portfolio also includes an in-cabinet solution for light applications. The on-machine option requires only a single cable from the cabinet, reducing the number and length of cable runs and potential failure points.

The ArmorBlock IO-Link master includes connectivity for up to eight IO-Link sensors. The master and sensors share an IP address, helping end users reduce the cost and time to commission equipment.
