- 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.

- 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.
