Introduction: “Can’t Download to Faulted Controller” If you get the error “Can’t Download to Faulted Controller”, we need to clear the fault before downloading. First of all, be sure you want to download to the processor. When you download, the existing logic is replaced by the logic in your offline Read More »
Introduction to ControlLogix Communication Path Needed Error In this section, we’ll resolve the ControlLogix Communication Path Needed error in Studio / RSLogix 5000. Eventually, we all get this error at some point. The error is 701-8004280D. I will show you the method I use to resolve this error. The reason Read More »
Introduction to the Arduino Button Input Example In this section, we’ll discuss the Arduino Button Input Example that comes with the Arduino IDE. Basically, we’ll connect a button to pin 2, and simply have this button energize a light. Presently, you will find this example under File | Examples | Read More »
Introduction to the Arduino Analog Output In this section, we’ll set up an Arduino Analog Output. Analog signals are variable. In contrast, digital (discrete) signals are on or off. On the UNO, pins 3, 5, 6, 9, 10, and 11 support Analog Output. I’ve set this example up on TinkerCad. Read More »
Introduction to Arduino Analog Input In this post, we’ll walk through the example for the Arduino Analog Input. You will find this example under File | Examples | Analog. In this case, I’ll be using the Arduino UNO for this simulation. However, the example will work with many of the Read More »
Introduction to Arduino Blink Without Delay The Arduino Blink Without Delay example allows you to blink a light without using the delay() function in the Arduino IDE. In short, this means you are not stopping the logic from scanning. This, you can execute other instructions while the light is waiting Read More »
Introduction to ControlLogix Bookmarks ControlLogix Bookmarks allow you to quickly navigate back to a location in logic. By comparison, in the older versions of RSLogix, you had to write down the ladder and rung. When tracing down bits, you need to easily navigate to sections of logic. Turn on the Read More »
Introduction to Determining ControlLogix Firmware Revisions There are several ways to go about Determining ControlLogix Firmware Revisions. One method is to use the Web Page served by the ENBT or EN2T. Another method is to go to the properties of the module in the RSWho Screen. Likewise, you can get Read More »
Introduction to the ControlLogix Sequencer Output (SQO) Basically, we use the ControlLogix Sequencer Output (SQO) instruction as a “Drum Switch”. That is to say, we have a file of bit patterns. Each time we trigger the sequencer output instruction, the next bit pattern will be dumped to the output. In Read More »
Introduction to sending Arduino Temperature to ControlLogix. In this section, we’ll send an Arduino Temperature to ControlLogix. Instead of an Arduino, you could also use the ESP8266. We’ll use the DHT22 sensor. Basically, we’ll just send this data over the serial port. Obviously, we need to also configure the ControlLogix Read More »
