Introduction to PID Terminology PID Terminology is essential to understanding how PID works. For this reason, we’ll go through various terms you will see when reading about PID. In short, PID itself stands for Proportional, Integral, and Derivative. Basically, the purpose of PID is to hold analog values at a Read More »
Introduction to PlantPAx with Ladder Logic There might be several reasons you need to use PlantPAx with Ladder Logic. If your site does not have a license for function blocks, then you might want to use ladder logic. Additionally, some factories will simply prefer to use Ladder logic over function Read More »
Introduction to FactoryTalk View SE Trends and Data Log With FactoryTalk View SE Trends and Data Log, we will log background data, and plot that data onto a trend chart. Without the data log, the trend chart will only show live data at the time the trend was started. Basically, 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 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 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 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 »
Introduction to FactoryTalk View SE Navigation FactoryTalk View SE Navigation is slightly different than the navigation in FactoryTalk View ME. FactoryTalk View ME will typically use a “Goto Display” button. By Comparison, FactoryTalk View SE will use the display command within a standard command button. By using the standard display Read More »
Introduction to PlantPAx 4 Control Valve The PlantPAx 4 control valve object allows us to control the position of a valve, and monitor it’s status. Obviously, we need to send the valve a command, and read the process variable to be sure it is in position. In detail, we’ll walk Read More »
Introduction to PlantPAx 4 Motor Operated Valve The PlantPAx 4 Motor Operated Valve instructions allows us to open or close a valve. Additionally, it provides some diagnostic information about the valve. That is, we will get an alarm if the valve fails to open or shut. Even if we get Read More »
