Troubleshooting
Introduction The purpose of this chapter is to assist in troubleshooting the EtherNet/IP
Communications Auxiliary.
EtherNet/IP Modules of
Operation The EtherNet/IP Communications Auxiliary has four EtherNet/IP modes of
operation:
• Power-Up Reset Mode,
• Run Mode,
• Recoverable Error Mode, and
• Unrecoverable Error Mode.
SHOCK HAZARD:
Servicing energized industrial control equipment can
be hazardous. Electrical shock, burns, or unintential actuation of
controlled industrial equipment may cause death or serious injury .For
safety of maintenance personnel as well as others who may be exposed
to electrical hazards assicated with maintenance activities, follow local
safety related work practices (e.g., 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.
