Introduction to the Data Log in FactoryTalk View ME. In this section, we’ll set up a Data Log in FactoryTalk View ME. Whenever you set up a trend chart, usually, you want a data log model to go along with it. When you set up a trend without a data Read More »
Introduction to ControlLogix over the Internet In this section, I’ll show you how easy it is to connect to a ControlLogix system over the Internet without proper security. Undoubtedly, using this procedure will cause a severe security threat. The purpose of this to show how easy a simple change in Read More »
Introduction to RS232 to DH+ Passthru on the SLC 5/04 With RS232 to DH+ Passthru, we will connect through the serial port on a processor, and access the DH+ network. With this in mind, another option would be the 1784-U2DHP. However this device might cost around $2,000 to purchase. In Read More »
Introduction to the SLC-500 ASCII Read Line (ARL) We use the SLC-500 ASCII Read Line (ARL) to read ASCII data from the serial port. Particularly, this might be from a bar code reader, weigh scale, or RFID reader. Basically, we will just execute the ARL instruction every second, to see Read More »
Introduction to Work Ethics in the 2020’s In this post, I wanted to take a break from the usual topic of electronics, and PLC’s I’ll just share some ideas that I have about proper Work Ethics in the 2020’s. In today’s changing world, we hear about strikes and protests. We Read More »
Introduction to the SLC-500 ASCII Write (AWT) We use the SLC-500 ASCII Write (AWT) instruction to write data through the serial port of the processor. Since ASCII is a world wide standard, this ability greatly increases our ability to communicate with other devices. For example, many weigh scales support ASCII, Read More »
Introduction to SLC-500 Trending There are several reasons you would set up SLC-500 Trending. With Trending, you will generally track analog signals over time. Although you can also track discrete (on/of) signals, a Histogram is usually better suited for that. Although you can track any signal, I’m just going to Read More »
Introduction to SLC-500 Advanced Diagnostics The SLC-500 Advanced Diagnostics feature allows you to quickly locate an output in your SLC-500 Project. This is most effective if the project is organized, and documented well. Instead of randomly searching through logic to find your output, you will be able to find them Read More »
Introduction to SLC-500 Online Editing When performing SLC-500 Online editing, you are making the changes to the program while the process is running. However, you must be careful. Be sure to fully understand what effects your changes will have on the system. It’s important to realize that your key switch Read More »
Introduction to PlantPAx 4 PID We typically use the PlantPAx 4 PID (P_PIDE) in closed loop controls. For example, we have a heating process. This heating process provides a control value (CV) to the heat bands. We monitor the process variable (PV) to see what effect our output has. Our Read More »
