WEIDMULLER IP20 and IP67 IO-Link Master modules use the IO-Link open standard (IEC 61131-9) serial communication protocol to connect and communicate data to and from sensors and actuators. This increased transparency down to the sensor-actuator level helps improve diagnostics and efficiency, increase machine availability and reduce downtime. Products provide simple, user-friendly web-based configuration and monitoring. This allows users to conveniently change parameters using the web server and provides for both on-site and remote testing and diagnostics without the need for additional software. Processes and procedures can be simulated without a connection to the controller for simplified phase commissioning, and faster service response in the event of unplanned downtime.
