Mastering PLC Programming: A Comprehensive Guide to RSLogix 500

Hardware Connection Methods

  • Start pushbutton: I:1/0 (momentary)
  • Stop pushbutton: I:1/1 (normally closed)
  • Motor output: O:2/0 Rung: XIC I:1/0 (Start) and XIO I:1/1 (Stop) in series, then OTE O:2/0 in parallel with seal-in XIC O:2/0.

Understanding the difference is vital for modern engineers.

Step‑by‑Step: How to Program a Simple Latch Circuit in RSLogix 500

A typical workflow in RSLogix 500 involves the following steps:

  • Buy a used MicroLogix 1100 or 1400 on eBay (often under $200) plus a 24V power supply.
