Common 1734-AENTR failures

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

  • 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-AENTR drops in with almost no setup. Replace it when the network is down or the module is physically damaged. We stock the 1734-AENTR. Order by 5:00 PM Central for same-day shipping.
RepairRepair makes sense on the 1734-AENTR 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-AENTR symptoms we see most often are “Adapter drops off the network” and “POINTBus faults”. If a replacement is already installed, repairing the failed 1734-AENTR gives you a tested spare on the shelf for the next failure. Repaired 1734-AENTR units are function-tested before return and carry a 1-year warranty.
