Introduction to XModem over Ethernet WiFi To set up XModem over Ethernet WiFi, we’ll have to get a few things set up first. In this case, I’m running Debian Bullseye. I will be using Minicom in this example. I’m transferring a file to an AltairDuino. You can get these at Read More »
Introduction to Converting RSView32 to FactoryTalk Before Converting RSView32 to FactoryTalk we will need to install some software. First of all, I have RSView32 on a Windows XP computer. This is a 32 bit machine. Secondly, I have FactoryTalk View SE version 12 on a 64 bit computer. Thirdly, I Read More »
Introduction to RSView32 with ControlLogix In this section, we’ll be using RSView32 with ControlLogix. RSView32 is an HMI interface. That is to say, it’s for humans to interface with machines. With RSView32, you might display data in the processors memory. That way, a machine operator can read values such as Read More »
Introduction to the Altairduino – 8800 Kit In this section, I wanted to show you the Altairduino – 8800 Kit. I’ve always been interested in vintage computers. My first computer was the Commodore 64. I bought this from COMB magazine. Modern computers are fast, and reliable. However, by going back Read More »
Introduction to the ControlLogix Totalizer (TOT) The ControlLogix Totalizer (TOT) tracks the total amount of a product. In this example, we’ll have an input of barrels / second. However, you can change the time base of the instruction to reflect minutes, or hours. The ControlLogix Totalizer (TOT) is available in Read More »
Introduction to Scaling Data in Ladder Logic with ControlLogix In this section, we’ll be Scaling Data in Ladder Logic. Scaling simply means that we convert a raw value into engineering units. For example, 4-10mA of input will give us a raw value of 3277 to 16383. This number does not Read More »
Introduction to ControlLogix BSR — Kill the Bit (with Bit Shift Right) In this section, we’ll cover the ControlLogix BSR — Kill the Bit. This is a very simple game from the 1970s. Computers, such as the Altair 8800 and IMSAI 8080 have a front panel display. This LED Display Read More »
Introduction to ControlLogix Rate Limiter (RLIM) We use the ControlLogix Rate Limiter (RLIM) to slow the rate of change from a tag. For example, if the operator changes a setpoint, we might not want to feed the new setpoint directly to a PID. This could cause a large bump in Read More »
Introduction to the ControlLogix Lead/Lag Instruction (LDLG) The ControlLogix Lead/Lag Instruction (LDLG) is useful in PID Loops. We might use this with the FeedForward (FF), or Bias input. The purpose of the Feed Forward is to anticipate changes. For example, if our load changes, we can immediately offset the output Read More »
Introduction to FactoryTalk View Sliders FactoryTalk View Sliders allow an operator to input data. This is a graphical way for the operator to easily see the limits of a tag. Operators will simply slide a “knob” to select a value. Not only does this limit the operator to a certain Read More »
