ControlLogix and CompactLogix Datalogging to CSV File

A couple of years ago, prior to the release of Studio 5000 v21, Rockwell demonstrated a future feature for it’s new “multi-core” programmable automation controllers. This new feature was a very robust, controller based data logging system. Unfortunately, since that demo a couple of years back nothing more has been hear about this feature. … Read More »

What are PlantPAx Process Objects?

I’ve been getting a lot of questions about PlantPAx lately. Specifically about PlantPAx as it pertains to HMI and SCADA systems. While PlantPAx is a very wide and broad topic, when I get the above question it typically relates to Rockwell’s highly developed faceplates, formerly known as the “PlantPAx Library of Process Objects.” The … Read More »

Can multiple Logix PLC’s control the same Ethernet I/O?

A client recently asked me if multiple CompactLogix (or ControlLogix) processors could control the same Ethernet I/O? Since RSLogix5000 has supported Ethernet I/O, its been possible to setup two processors to control, or “own,” the same remote rack of Ethernet I/O. However, the processor which attached to the I/O first would  be the … Read More »

ControlLogix support for adding I/O online

How to test the loading of Non-Volatile memory in your CompactLogix or ControlLogix

Similar to other Allen-Bradley PLC’s, the CompactLogix and ControlLogix Controllers give you three options for loading the Controller’s memory “image” from non-volatile memory (CompactFlash, SD, etc.) These “load modes” are “User Initiated,” “On Power Up,” and ”On Corrupt Memory.” Below I’ll walk you through how to test each of these modes, of which ”On Corrupt … Read More »

Why your CompactLogix or ControlLogix Real Time Clock (DateTime) may be a few hours off

A client recently called frustrated that the real time clock in his CompactLogix processor was always off by 4 hours. While I had heard this complaint in the past, since I hadn’t run into it myself I needed to do a little research to understand what this client was experiencing. I found that prior to RSLogix 5000 version 16, using a GSV (“get system variable”) instruction to … Read More »
