More Information

Overview Manuals Program Planning DH-485 Communication System Integration Application
  • Provides 4K user-program memory for local SLC 500 control.
  • Supports up to 960 local I/O points in a modular SLC 500 system.
  • Uses an integrated DH-485 port for programming and network communication.

1747-L514 is an Allen-Bradley SLC 5/01 processor with 4K user-program memory for 1746 modular SLC 500 systems.

It scans the ladder program, updates local chassis I/O through the SLC backplane, and provides typical program and I/O scan times of 8 ms/K and 2.6 ms respectively.

Before replacement, confirm the SLC 5/01 DH-485 communication role, slot-0 position, chassis power loading, installed 1746 I/O modules and saved program.

Availability, condition, price, and shipping time for 1747-L514 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Use 1747-L514 only where the approved ladder program and data tables fit its 4K user-program capacity.
  • Check scan-time margin with the actual instruction mix and installed I/O, rather than comparing it with higher-capacity SLC processors.
  • Review future program, data-handling and communication needs before retaining 1747-L514 in an expanded machine design.
  • Configure 1747-L514 Channel 0 as a DH-485 station; it responds to network requests and does not initiate DH-485 messages.
  • Set a unique node address and match the established DH-485 baud rate before reconnecting the processor to the network.
  • Use a compatible programming interface and confirm the existing Channel 0 settings before downloading or monitoring the application.
  • Install 1747-L514 in processor slot 0 of a compatible 1746 SLC 500 chassis.
  • Calculate chassis power demand from the processor and every installed 1746 I/O module before energizing the system.
  • When using expansion chassis, verify the expansion arrangement, end termination and saved I/O configuration before restoring the program.
  • Standalone conveyor sequencing and interlock control.
  • Small packaging machines with local discrete and analog SLC 500 I/O.
  • Utility skids and small machine cells requiring DH-485 supervisory communication.
Description
1747-L514 is an Allen-Bradley SLC 5/01 processor for modular 1746 SLC 500 control systems.

It provides 4K user-program memory for local machine control and uses its built-in DH-485 port for programming and network communication.

The SLC 5/01 responds to DH-485 commands but does not initiate messages. Confirm the existing chassis, installed I/O, power supply, DH-485 configuration, stored program and memory-backup requirements before replacement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 1747-L514 replace a 1747-L511 processor without changing the project?
Only after checking the saved program, installed I/O map, base-unit series, expansion layout and memory backup method. Both are SLC 5/01 processors, but the replacement must be tested with the actual application rather than selected by appearance alone.
Which memory module should be used to back up a 1747-L514 program?
Rockwell lists 1747-M1 and 1747-M2 as compatible memory modules for 1747-L514. Confirm the required program capacity and follow the documented jumper and power-down procedure before inserting or removing a module.
Can a USB laptop connect directly to the DH-485 network of a 1747-L514?
Use a supported DH-485 interface such as a 1747-UIC. A generic USB-to-RS-232 converter does not create a DH-485 connection and can lead to failed communications or incorrect troubleshooting.
Why does a replacement 1747-L514 communicate intermittently on an existing DH-485 network?
Check for a duplicated node address, incorrect baud rate, reversed network conductors, poor shield termination, an unsuitable interface converter, or an incorrectly restored Channel 0 configuration before replacing hardware again.
How can program loss be avoided when servicing a 1747-L514?
Upload and archive the verified application first, confirm the processor battery condition, and use a supported memory module where the project requires removable program backup. Do not rely on an unverified RAM image after prolonged storage or a depleted battery.
Can a 1747-L514 system be expanded simply by adding another local chassis?
No. Review the complete local-chassis layout, slot addressing, expansion hardware, end termination, power loading and the saved RSLogix 500 configuration. A physical chassis addition can change the addressing assumptions in the application.
Can the native communication port of 1747-L514 be converted to Ethernet by changing the cable?
No. Its native processor communication is DH-485. Ethernet integration requires an engineered interface or a migration design; changing only the cable does not add Ethernet capability.
