      Overview Manuals Common Applications Product Precautions
      Allen-Bradley 1747-L511 is SLC 5/01 controller with 1 KB memory. It executes an SLC 500 user program and communicates with programming and network devices over DH-485.
      • Executes the SLC 5/01 control program
      • Provides one kilobyte of user memory
      • Communicates through DH-485
      • Uses the 1746 SLC chassis and power-supply family

      1747-L511 operates with 1746 SLC chassis and backplane, 1746-P1 through 1746-P7 power supply, DH-485 network hardware, approved SLC 500 I/O configuration.

      Engineered applications include Legacy machine sequence control, Small SLC 500 automation cell, DH-485 controller network, SLC 5/01 processor replacement.

      Important Notice: Back up the program, record the chassis slot, power supply, DH-485 node settings and I/O configuration, and prove the complete machine sequence after controlled restart.

      Important Notice: The first document presents exact-model technical and engineering data. The second provides a separate installation, connection, commissioning and acceptance workflow.

      Legacy machine sequence control
      Runs the documented machine logic and I/O scan.
      Small SLC 500 automation cell
      Controls compact installed SLC systems.
      DH-485 controller network
      Connects programming or peer devices through DH-485.
      SLC 5/01 processor replacement
      Restores a 1 KB processor while preserving the project.
      Read the applicable Allen-Bradley instructions before work. Verify 1747-L511 and the installed Allen-Bradley SLC 500 control system configuration.
      1
      Verify the complete 1747-L511 marking and its assigned Allen-Bradley SLC 500 control system position before work.
      2
      Place the connected legacy machine sequence control process in the approved maintenance state.
      3
      Isolate applicable power and SLC program execution, backplane I/O and DH-485 communications field energy before disconnection.
      4
      Record every connector, conductor, address, firmware and software identity before removal.
      5
      Use ESD controls and protect keyed interfaces, exposed contacts and electronic assemblies.
      6
      Confirm the installed 1746 SLC chassis and backplane and 1746-P1 through 1746-P7 power supply against the approved project.
      7
      Restore power in a controlled sequence and review device, network and host diagnostics.
      8
      Prove the intended small SLC 500 automation cell function and retain the final test result.

      FAQS

      • What distinguishes the 1747-L511 processor in an SLC 500 chassis?
        It is the SLC 5/01 CPU with 1 KB of user memory; retain the complete 1747-L511 catalog identity and the existing chassis slot.
      • For 1747-L511, which communications interface is available on this SLC 5/01 controller?
        The documented processor communication is DH-485 through its DH-485 port, so the node arrangement and programming connection must be preserved.
      • For 1747-L511, which power-supply family is documented for the installed 1746 chassis?
        The official record identifies 1746-P1 through 1746-P7 supplies for the SLC system; verify the exact installed supply before transferring the processor.
      • For 1747-L511, what program information must be secured before removing the CPU?
        Back up the SLC 5/01 application and record the data-table state, processor mode, slot assignment and DH-485 node settings required by the installed machine.
      • For 1747-L511, why must the replacement stay within the 1 KB processor configuration?
        The controller's documented user-memory capacity is 1 KB. Confirm that the approved project fits and do not treat a different SLC processor catalog as an automatic substitute.
      • For 1747-L511, how should the chassis and backplane be handled during processor replacement?
        De-energize the 1746 chassis, confirm the power supply is off, protect the backplane connector and reinstall the CPU in the recorded processor position.
      • For 1747-L511, what does the discontinued lifecycle status change for maintenance planning?
        The product record lists discontinuation on January 31, 2017, so replacement work must preserve the exact catalog, approved project and compatible SLC 500 hardware.
      • What acceptance test is appropriate after restoring 1747-L511?
        Return power under control, confirm the processor and DH-485 communication state, then run the complete machine sequence and verify every configured input, output and interlock.
