  • Integrated DH+ Communication: Supports high-speed data exchange and multi-node industrial networks.
  • Versatile RS-232 Port: Configurable for DF1, DH-485, Modbus RTU, ASCII, and radio modem protocols.
  • 16K User Memory: Provides adequate storage for medium-scale logic programs and data tables.
  • Fast Execution Rates: Offers 0.9 ms/K scan time and 0.37 μs bit execution for responsive control.
  • Expandable I/O Capacity: Handles up to 4096 inputs and 4096 outputs across multiple chassis.
  • Flash EEPROM Support: Compatible with the 1747-M13 memory module for program retention.
  • Interrupt Handling: Includes selectable timed interrupts and discrete input interrupts for event-based tasks.
  • Rack-Based Modular Design: Fits standard SLC 500 chassis for easy system expansion and maintenance.

The 1747-L541 delivers the reliability and precision required for stable mid-range PLC control in industrial automation systems.

Frequently Asked Questions about 1747-L541
Question: What is the 1747-L541?
Date Update:03/06/2025
Answer:

The 1747-L541 is a SLC 5/04 processor module used in SLC 500 systems. It controls automation processes and communicates with I/O modules within the chassis.

Question: How do I program the 1747-L541?
Date Update:03/06/2025
Answer:

Programming is done using RSLogix 500 software:

  • Create a new project with the SLC 5/04 processor type.
  • Configure the processor and I/O configuration.
  • Write ladder logic or structured text programs.
  • Download the program to the processor via serial (Channel 0) or DH+ (Channel 1).
Question: How do I update the firmware?
Date Update:03/06/2025
Answer:

Firmware updates for the SLC 5/04 are typically not field-upgradable like newer controllers.
If you need a firmware update, you usually need to replace the processor module with an updated hardware revision.

Question: What is the maximum number of I/O modules supported?
Date Update:03/06/2025
Answer:

The 1747-L541 supports:

  • Up to 30 local I/O modules
  • 4096 I/O points maximum
Question: What is the default communication port setting?
Date Update:03/06/2025
Answer:

Channel 0 (RS-232):

  • Default: DF1 Full-Duplex
  • Baud rate: 19.2 Kbps
  • 8 data bits, no parity, 1 stop bit

Channel 1 (DH+):

  • Node address: 1
  • 57.6 Kbps default speed

You can adjust these settings in RSLogix 500 under the Channel Configuration window.
