Troubleshooting
Introduction
This chapter helps you to troubleshoot the EtherNet/IP communication
auxiliary module.
Modes of Operation
The EtherNet/IP communication auxiliary module has four EtherNet/IP
modes of operation:
• Power-Up Reset mode
•Run mode
• Recoverable Error mode
•Unrecoverable Error mode
SHOCK HAZARD: Servicing energized industrial control equipment can be
hazardous. Electrical shock, burns, or unintentional actuation of controlled
industrial equipment may cause death or serious injury. For safety of
maintenance personnel and others who may be exposed to electrical hazards
associated with maintenance activities, follow local safety-related work
practices (for example, the NFPS 70W; Part II, Electrical Safety for Employee
Workplaces, in the United States) when working on or near energized
equipment. Maintenance personnel must be trained in the safety practices,
procedures, and requirements that pertain to their respective job assignments.
Do not work alone on energized equipment.
ATTENTION: Do not attempt to defeat or override fault circuits. The cause of
a fault indication must be determined and corrected before attempting
operation. Failure to correct a control system or mechanical malfunction may
result in personal injury and/or equipment damage due to uncontrolled
machine system operation.
