Addressing in RSLogix 5000

Before you can program any PLC system, you have to understand how the addressing is done in that particulaur PLC. I have included a actual screenshot from RSLogix 5000 below that shows examples of addressing in RSLogix 5000.

Read on to get the details. Read more

Know How to Get Back to Where You Started

Making a given modification may be simple. Remembering what you have changed, and how to restore the PLC to its original state may not be so simple.

This is a trap that many programmers fall into. Read more

Connecting to an Allen-Bradley SLC and Going Online

I get a lot of questions about going online with a PLC. Here is a section from PLC Programming with RSLogix 500 that covers going online with an SLC 5/03.

Setting up an SCP in RSLogix 500

An SCP (Scale with Parameters) is really handy instruction in RSLogix 500. It scales any range of values to a range defined by the programmer.

One of the common uses of the SCP instruction is to take the value from an analog input and scale it to an engineering value. Read more

Equivalent Logic in PLC Programming

If you understand basic electrical diagrams, it is much easier to understand ladder logic.

In fact, that was the whole idea behind ladder logic. It was supposed to look, and work, like real electrical circuits Read more

RSLogix 500 Addressing in an Allen-Bradley PLC

There are a number of addressing schemes used by PLC manufacturers. Let’s take a quick look at how memory locations (including hardware I/O) are accessed with RSLogix 500. Along the way, I will define some terms. Read more
