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 »
Introduction to starting a new project in the SLC-500 Before starting a new project in the SLC-500 system, there are a few things we need to do to set up the processor regardless of the processor type. We will set up the path to your processor, configure the I/O, and Read More »
Introduction to FactoryTalk View SE Alarms FactoryTalk View SE alarms will be able to log alarm information and notify the operator when an abnormal condition occurs. For example, an abnormal condition would be a high or low level warming. Another example would be a simple bit that goes high, or Read More »
Introduction to the PLC-5 Day of Week Counter A PLC-5 Day of week counter is an easy way to find the day of the week for certain events in automation. For example: You want to test an alarm every Monday at 10am. There are complex algorithms that will calculate the Read More »
Introduction to PlantPAx 4 Analog Outputs With PlantPAx 4 Analog Outputs, you will scale analog information back to raw data to send to an Analog Output module. For example, we have a valve which requires 4-20ma, however the operator interface is set up for percentage. In this case, we might Read More »
Introduction to the ControlLogix 1756-DHRIO Module The ControlLogix 1756-DHRIO module allows you to interface with the older Data Highway Plus (DH+) Network. You can also connect to a maximum of four Remote I/O Racks per channel. Each 1756-DHRIO module has 2 ports. Each of which will support DH+ or Remote Read More »
Introduction to PlantPAx 4 Analog Inputs In this section, we’ll discuss PlantPAx 4 Analog Inputs. There are three instructions that we will set up. The first instruction will be the channel (P_AIChan). Secondly, we’ll discuss the Analog Input (P_AIn) instruction. Optionally, you can to import the Module Status (L_ModuleSts) to Read More »
