Introduction to Tuning PlantPAx P_PIDE with Simulator Before Tuning PlantPAx P_PIDE, please reset your simulator. This way, we’ll get back to a known configuration. To reset the simulator, use your test button until you get to the reset option. Then press Up then TEST again. In the last sections, we’ve Read More »
Introduction to Configuring PlantPAx Objects for PID In this section we’ll be Configuring PlantPAx Objects for PID. In the previous sections, we imported our faceplates. Additionally, we set up our function blocks for PID. Finally, we assocated the faceplates with the function blocks. At this point, we are ready to Read More »
Introduction to Function Blocks for PlantPAx PID In this section, we’ll add our Function Blocks for PlantPAx PID. In our previous sections, we imported the add-on instructions. At this point, we are ready to set up our function block logic. If you have not already done so, created a periodic Read More »
Introduction to Preparing PlantPAx for PID In this section, we’ll be Preparing PlantPAx for PID. We’ll assume you already have a running PlantPAx project. If not, you’ll have to install PlantPAx using the PlantPAx process library. Be sure your HMI Images, macros, tags, and global objects are imported. You should 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 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 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 »
