Important Technical Notes

1. System Requirements:​ Requires 1746 chassis (A4, A7, A10, A13) and 1746 power supply. Must be installed in slot 0.

2. DH+ Network:​ Requires proper network termination, addressing (0-77 octal), and cable installation. Maximum 64 nodes on DH+ network.

3. Memory Capacity:​ 16K memory suitable for medium complexity applications. Consider program size and data requirements.

4. Battery Maintenance:​ Replace lithium battery (1747-BA) every 2 years or when battery LED indicates low voltage.

5. Programming Software:​ Requires RSLogix 500 software for programming and configuration.

6. I/O Expansion:​ Local I/O limited to 30 modules. Remote I/O via 1747-ASB module expands to 960 I/O points.

7. Power Requirements:​ Ensure power supply provides adequate current for processor and I/O modules. Higher power consumption than 5/03 processors.

8. Network Configuration:​ Proper DH+ network configuration (baud rate, node address) is critical for network communication.

9. Environmental Conditions:​ Install in appropriate enclosure for protection. Operating temperature limited to 0-60°C.

Note: For complete installation guidelines, wiring diagrams, programming instructions, and detailed technical data, consult the official Allen-Bradley SLC 500 Technical Manual. Always verify the exact model number configuration with the manufacturer, as notation variations may occur.
