FANUC Alarm HOST-284 — SMB: Secure Signature from PC failed

Description

The Secure Signature failed on a network message sent from the PC to the robot controller.

Remedy · Remède

The PC server has message signing enabled. This forces the robot controller to perform Secure Signatures to verify communication integrity. If the problem persists, document the events that led to the error, and call your FANUC or FANUC Robotics technical representative.
