FANUC Alarm PRIO-493 — Modbus Socket Error

Description

The Modbus TCP Server was not able to open and use a TCP network socket.

Remedy · Remède

This alarm generally implies that the Ethernet or TCP/IP interface is not set up correctly. For example, if no IP address is defined, then the TCP/IP stack cannot initialize. Verify network connectivity using the ping utility (on the robot, and also on the local PC).
