The Allen Bradley 1747-PT1 Hand Held Terminal Tutorial
The Allen Bradley Handheld Terminal, affectionately known as 1747-PT1, is something that was more popular when Ronald Reagan was president and Duran Duran was a cool new wave band. That’s the 1980’s for those who are not my generation. I’m kind of a nostalgic guy so digging into how a hand held programmer works is some sort of weird interest for me. For good reason these devices were left in the closest to gather dust once personal computers came around and you could program your PLC in DOS. With the advent of RSLogix and cheap laptops there’s very little reason to brush the dust of your 1747-PT1. Then again, maybe there is if all you want to do is just check a value or quickly change a preset on a timer. You could be the coolest geek around with this puppy strapped to your belt. Just beware your boss and work mates might think you’re goofing of playing game boy.
This article is different then a regular 1747-PT1 tutorial. As the saying goes, “If you don’t use it you lose it”, so this is meant to be more of a cheat sheet or a quick refresher course. I assume you all ready have a knowledge of how the SLC500 processors store files and how to address memory. I’m more concerned with how to get around the menu structure of the 1747-PT1 once they’ve escaped my brain cells after a couple months of non-use. If you’re looking for something more in depth then you can still download “The Getting Started Guide for HHT” and/or the “1747-PT1 User Manual” from the Rockwell Automation site.
The 1747-PT1 hand held programmer is only good on these SLC-500 processors.
SLC 500 Modular 5/01 and 5/02
This means the 5/03, 5/04 and 5/05 processors are NOT supported.
