SLC-500 Advanced Diagnostics

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 »

SLC-500 Online Editing

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 »

SLC-500 Messaging

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 »

SLC-500 Clock

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 »

SLC-500 Digital Input Module

Introduction to the SLC-500 Digital Input Module The SLC-500 Digital Input module detects the status of field devices which are either on or off.  This is any type of switch.  For example:  float switches, pressure switches, push buttons, and selector switches are digital input devices.   The auxiliary contacts of a Read More »
