AB 1756-L73 ControlLogix Controller CPU System

1. Introduction to Armor ControlLogix Controllers:

• The Armor ControlLogix controller integrates a 1756-L72 or 1756-L73 ControlLogix controller with two EtherNet/IP DLR-capable 1756-EN3TR communication modules. This assembly is enclosed in an IP67-rated housing for machine mounting.
• Specific catalog numbers for the Armor ControlLogix controllers are 1756-L72EROM and 1756-L73EROM. Additional installation details can be found in the Armor ControlLogix Controller Installation Instructions (1756-IN061).

2. Energy Storage Modules (ESM) Considerations:

• ESM Functionality:
  • The Armor controllers (1756-L72EROM and 1756-L73EROM) share identical functionality with 1756-L72 and 1756-L73 controllers.
  • Unique to Armor controllers is the inability to remove or replace the energy storage modules (ESM).
• Compatible ESM Modules:
  • ESM modules currently installable in 1756-L7x or 1756-L7xXT controllers are listed.
  • Specific modules come pre-installed based on the controller type.
• Removal Guidelines:
  • Caution is advised when removing ESM modules after power loss, waiting for the OK status indicator transition from Green to Solid Red to OFF.
• Specific ESM Usage:
  • Details on the usage of the 1756-ESMNSE module with specific controllers.
  • Usage considerations for 1756-ESMNRM, 1756-ESMNRMXT, and special scenarios with 1756-ESMNSE module.
• Non-Removable Modules:
  • Highlighting that once installed, 1756-ESMNRM or 1756-ESMNRMXT cannot be removed from 1756-L7x or 1756-L7xXT controllers.
• Final Note:
  • Emphasis on the non-removability and irreplaceability of Armor controller energy storage modules.
