Plc Rslogix 500 ●

RSLogix 500 is designed specifically for "tagless," rack-based controllers. It is incompatible with the newer ControlLogix/CompactLogix platforms. The primary controllers supported are:

✅ Maintained start/stop control
✅ Overload protection with fault latch
✅ Accumulated run time tracking (hours counter)
✅ One-shot start prevents jamming
✅ Manual fault reset required for safety
✅ Ready for HMI integration

RSLogix 500 is a Windows‑based programming software package developed by Rockwell Automation. It was designed specifically to program and troubleshoot the SLC 500 and MicroLogix families of PLCs. The software uses a ladder logic editor, which mimics the electrical relay cabinets of the past, making it intuitive for electricians and engineers alike.

Originally launched in the mid‑1990s, RSLogix 500 succeeded older DOS‑based editors (such as APS and 6200 Series). It brought a graphical user interface, online editing capabilities, and a robust tag‑based data model to the SLC and MicroLogix platforms. Even today, thousands of factories run critical processes on controllers programmed with RSLogix 500. plc rslogix 500

Key distinction: Do not confuse RSLogix 500 with RSLogix 5000 (now called Studio 5000), which programs the newer ControlLogix and CompactLogix platforms. The number “500” refers to the SLC 500 processor family.

RSLogix 500 does not handle communication drivers directly. Instead, it relies on RSLinx Classic (Rockwell’s communication server). To go online with a PLC, you must first configure a driver in RSLinx, then select that driver from within RSLogix 500.

Common drivers include:

Tip: Always verify baud rate, node address, and COM port settings. A common mistake is mismatched serial parameters between the PLC and the PC.

Understanding the memory model is key to using RSLogix 500 effectively. Unlike Studio 5000’s tag‑based system, RSLogix 500 uses fixed‑address data files.
