Installation Guide

1. Mounting: Install on DIN rail or panel mount using the integrated mounting tabs. Maintain adequate clearance for ventilation.
2. Power Connection: Connect 120V or 240V AC power to the controller's power terminals. Verify voltage selection if applicable.
3. I/O Wiring: Wire 24 AC inputs and 16 relay outputs per the wiring diagram. Use appropriate wire gauge (typically 14–22 AWG).
4. Communication Setup: Connect programming cable to one serial port. Configure the second port for HMI, modem, or device communication.
5. Programming: Use RSLogix 500 software to develop and download ladder logic programs to the controller.
6. Protocol Configuration: Set communication parameters (baud rate, protocol) via RSLogix 500 or the controller's front panel.

FAQ

Q: What software is used to program the 1762-L40AWAR?
A: The controller is programmed using Rockwell's RSLogix 500 software.

Q: Can the 1762-L40AWAR communicate over Ethernet?
A: No. This model has serial ports only. For Ethernet connectivity, use the 1761-NET-ENI interface module or select a different controller series.

Q: What is the difference between 1762-L40AWAR and 1762-L40AWA?
A: The "R" suffix typically indicates relay outputs (both have relay outputs). Verify specific features with the datasheet as suffix variations may indicate firmware or hardware revisions.

Q: How much user memory is available?
A: The controller provides 6 KB of user program memory.

Selection Tips

• Verify I/O count: 24 inputs and 16 outputs match your application requirements
• Confirm power availability: 120/240V AC required
• For applications needing more I/O, consider MicroLogix 1400 or CompactLogix controllers
• Order RSLogix 500 software if not already available
• Consider communication requirements—serial only for this model
