I was recently called into a “consumer goods” plant to look at a communication problem with Point I/O. The night before I was told all the Point I/O, which had been successfully tested overseas, was no longer working. However, when I arrived on-site the problem was limited to just four of the many racks. The on-site engineer described the problem as a lack of communications between the Point I/O and ControlLogix. The ...Read more... - Device Level Ring: Adding a Remote I/O Chassis
I first began using ControlLogix in 2001, back when the software and firmware were both at version 7.

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 one to control the I/O, and ...Read more... - ControlLogix, CompactLogix – Can multiple controllers control the same Ethernet I/O?

There are a couple of different ways of thinking when it comes to in-program documentation, particularly the use of comments. One main methodology I see is to use documentation liberally (since it’s free), placing comments on as many rungs as desired. The other methodology is that less is more, with more emphasis placed on variable tags and ...Read more... - Alias Tags – Do you use them (Q&A)
One limitation of legacy programmable controllers like the PLC-5, SLC-500, and MicroLogix, was the inability to save “address names,” known as “symbols” in the aforementioned products, directly to the controller. And since these “symbols” could only be saved with the offline project, in order to display them while online required that you match-up the correct offline ...Read more... - ControlLogix – Programming: Different Ways of Accomplishing Your Goals
Programmers can accomplish a task in many ways. They have many options available, and it is almost to the point that you can use whatever coding style your preference is for a task at hand.
