Introduction to ControlLogix File Bit Compare The ControlLogix File Bit Compare instruction searches for mismatched bit between the source and reference tags. There are several uses for this instruction. One use would be for alarms. We can compare the source value against a reference of 0. in this case, the Read More »
Introduction to ControlLogix Sequencer Instructions ControlLogix Sequencer Instructions, such as Sequencer Input (SQI) and (SQO) walk through a set of instructions, and wait for specific conditions to make. For some projects, sequencers might be the entire programming strategy. Basically, the SQO instruction will energize a set of outputs. When the Read More »
Introduction to ControlLogix Bit Shift Instructions ControlLogix Bit Shift Instructions will shift bits in an array to the left or to the right. Of course this depends on which instruction you use. Obviously, Bit Shift Left (BSL) will shift the bits in an array to the right. On the other Read More »
Introduction to PLC-5 I/O Configuration It’s important to realize that you do not have to set up PLC-5 I/O Configuration for your project to work. There are advantages, however for taking the time to document the modules in each chassis. First, it’s a more visual way for a troubleshooter to Read More »
Introduction to FactoryTalk Function Key Assignments FactoryTalk Function Key Assignments allow you to assign function keys to objects on your graphics display. It’s important to realize that some panelview terminals do not have a touch screen. In this case, we need a different way for the operator to interact with Read More »

At the same time, we’ll talk about various instructions that utilize each data file. It’s important to realize that Read More »
Introduction to Programming the ATTINY13 (Microcore) When Programming the ATTINY13 (Microcore), in this case, we will use another microprocessor as our programmer. We’ll take a look at the connections we need to make. Additionally, we’ll look at the different options we have available before flashing the ATTINY13. The ATTINY 13 Read More »
Introduction to Burning the Atmega328 Bootloader By Burning the Atmega328 Bootloader, you use a little more memory in the chip, but for most users, it’s easier to upload future projects. Basically, the bootloader allows the microprocessor to receive a new project from your pc through the TX and RX pins. Read More »
PLC-5 Latch Vs Seal There are a few differences in the PLC-5 Latch Vs Seal. In this section, I’ll explain the operating of each type, and some dangers associated with both methods. Always be very careful when making any changes to the PLC program. Undoubtedly, you will want to get Read More »
Introduction to PLC-5 Counters PLC-5 Counters count rung transitions. More specifically, the counters count the false to true transition. In the PLC-5, there are two types of counters: The Up Counter (CTU), and the Down Counter (CTD). While you won’t always see a CTD, it’s almost always associated with a Read More »
