Common 1734-AENT failures

Failure patterns we regularly see on POINT I/O EtherNet/IP adapter hardware like the 1734-AENT:

Adapter drops off the network: port / transceiver failure with good cabling
POINTBus faults: backplane connector damage on the adapter or first module
Field power input section failure leaving the bank unpowered
Rotary address switches worn
Overheating in a sealed enclosure

Repair or replace?

ReplaceA POINT I/O EtherNet/IP adapter holds little more than a network address, so a replacement 1734-AENT drops in with almost no setup. Replace it when the network is down or the module is physically damaged. The 1734-AENT is on our shelf now and ships the same day for orders placed before 5:00 PM Central.

RepairRepair makes sense on the 1734-AENT when the failure is a connector, port or power-section fault on an otherwise sound board, or when you have several failing modules and want them returned as tested spares. The two 1734-AENT symptoms we see most often are “Adapter drops off the network” and “POINTBus faults”. If a replacement is already installed, repairing the failed 1734-AENT gives you a tested spare on the shelf for the next failure. Each 1734-AENT we repair goes back function-tested with a 1-year warranty.
