Installation Guidelines

  • Ensure the ControlLogix chassis is powered down before inserting or removing the 1756-ENET module to prevent electrical damage.
  • Verify that the module is fully seated in the chassis slot and that the locking tab is engaged.
  • Follow standard ESD (electrostatic discharge) precautions during handling to protect sensitive internal components.
  • Use appropriate shielded Ethernet cabling to minimize electromagnetic interference (EMI) in industrial environments.
  • Maintain proper ventilation within the cabinet to stay within the module's thermal dissipation limits.

FAQ

Is the 1756-ENET still supported by the manufacturer?

No, the 1756-ENET was discontinued by Allen-Bradley on June 23, 2010. We provide this unit as a legacy replacement part for existing systems.

What is the difference between Series A and Series B?

Series A and B represent different hardware revisions of the 1756-ENET. Please check your current module's label or your system documentation to confirm which series is required for your specific application, as they may have different firmware or hardware compatibility requirements.

Does this module require external power?

No, the module draws its operating power directly from the ControlLogix backplane. Ensure your power supply module is sized to accommodate the 13.3W maximum power dissipation of this unit.
