Introduction to Node-Red Boolean Logic Node-Red Boolean Logic is very simple to use. Regardless of your knowledge level, it’s usually simpler to state our logic goals in plain English. Undoubtedly, we might be able to accomplish some logic tasks with a function node. However, the Boolean Logic nodes allows us Read More »
Introduction to Node-Red Inject and Debug Node-Red Inject and Debug are two nodes that I use most often for testing and debugging a flow. On one hand, the Inject node allows you to send a message to another node. On the other hand, debug will show the payload coming out Read More »
Introduction of ControlLogix To Alexa Today, we’ll discuss how to connect ControlLogix To Alexa. When a bit becomes true in the ControlLogix processor, we’ll have Alexa speak a specific phrase. Additionally, it’s possible to speak to Alexa to set a bit in the processor. However, for this post, we’ll just Read More »
Introduction to Node-Red with Mosquitto At this time, I would like to explain how Node-Red with Mosquitto can enhance your ability to communicate between devices. For example: if you have an ESP32 or ESP8266, you can publish data to a Mosquitto “broker” and another device can receive that data. In Read More »
Introduction to ControlLogix/NodeRed Data Log To set up the ControlLogix/NodeRed Data Log, you must first install Node-Red. Node Red is a free, open source service that allows you to integrate connections from different types of automation devices. There are many documented procedures and youtube videos on this. Node Red is Read More »
Introduction to Node-Red with ControlLogix In this section, I’ll discuss setting up Node-Red with ControlLogix. Basically, we just need to install the Eth-IP node in Node-Red (for CIP). After that, we just configure the IP address of the Ethernet Module, the slot the processor is in, then declare the tags Read More »
Introduction to Arduino with Allen-Bradley DF1 The purpose of this post is to document my progress on using Arduino with Allen-Bradley DF1 protocol. Particularly, for this experiment, I am using an Arduino MEGA with the MAX232 module. The mega has 3 UART ports. Also, I’m using the SLC 5/04 processor. Read More »
Introduction to Common Logic Gates We use common logic gates to display the flow of a process. These gates include AND, OR, NOT, NAND, NOR, XOR, and XNOR. These logic gates convert a process into plain English in a way that anyone can understand how they work. By the same Read More »
Introduction to Arranging FactoryTalk View Objects One of the keys to keeping your project looking nice is properly Arranging FactoryTalk View Objects. You want to align and space your object evenly. At the same time, proper grouping helps you move and duplicate objects for similar parts of your system. Aligning Read More »
Introduction to the 74CH93 Binary Counter The 74CH93 Binary Counter has several uses. In the first place, you might use the counter as a divider. In this case, you can divide counts by 2, 4 or 8 for use with lower frequency devices. Additionally, you can use it to provide Read More »
