A Phillips Connect PLC reader is a device that reads and shares data from gateways and sensors. Reads trailer ABS and sensor data directly through the standard 7-way connection. Delivers instant access to fault codes and system diagnostics, giving fleets clear visibility into trailer health and helping ensure compliance while reducing troubleshooting time.

A PLC reader in a trailer is a component of the communication system, which uses the trailer's power supply lines for bidirectional data transfer with the tractor, allowing diagnostic functions and messages to be sent over the power lines instead of dedicated wires.
