Troubleshooting
Introduction
The purpose of this chapter is to assist in troubleshooting the E1 Plus EtherNet/
IP module.
EtherNet/IP Modes of
Operation
The E1 Plus EtherNet/IP Module has four EtherNet/IP modes of operation:
Power-Up Reset Mode, Run Mode, Recoverable Error Mode, and Unrecoverable
Error Mode.
Power-Up Reset Mode
During Power-Up Reset Mode, the following occurs:
ATTENTION: 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, as well as other who may be
exposed to electrical hazards associated with the maintenance
activities, follow the 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.
