Introduction to ControlLogix Self-Running Timers ControlLogix Self-Running Timers will generate a pulse. Basically, we can use this pulse to trigger other instructions, such as Messaging, and Bit Shift Registers. Another way to use self-running timers is to create a watchdog. In this case, the timer will generate an alternating high Read More »
How to fix PIDE Stuck High or Low in ControlLogix Using Function Blocks in ControlLogix, you can get the PIDE Stuck High or Low. This can occur when you are tuning a loop. To begin with, you only have proportional gain when tuning the loop. Your Process Variable could be Read More »
Introduction to Common PID Setup Mistakes In this section, I’ll discuss some common Common PID Setup Mistakes in ControlLogix. Obviously, an incorrect PID setup can be frustrating. The PID instruction will not calculate the results you expect for the output. Furthermore, your loop will be unstable, and inconsistent. Common mistakes Read More »
Introduction to How Numbering Systems Work When working with any PLC such as ControlLogix (or any digital computer), it’s important to understand how numbering systems work. The numbering system we are all used to is base-10 (Decimal). Mainly, that’s because we have 10 fingers. In the decimal numbering system, there Read More »
