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 »
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 SLC-500 Messaging With SLC-500 Messaging, we will transfer the contents of a data file from one processor to another. There are many reasons this might be necessary. For example, if one section of a conveyor shuts down, we might want to tell the upstream conveyor to shut down Read More »
Introduction to FactoryTalk View with SLC-500 using OPC In this post, I’ll show you how I connect FactoryTalk View to SLC-500 using OPC in RSLinx. This procedure also works for the PLC-5. In this example, I have a SLC 5/04 running on DH+. It does not matter what your communication Read More »
Introduction to the SLC-500 Clock The SLC-500 clock is accessed through the Processor Status file (S2). As a result, we can use these data table addresses for events that occur during a certain time of the day. As an example, you might sound a horn every hour at break time. Read More »
