Learn Logix Part 2.8. This article gives an overview of the CompactLogix communication modules and their features.
Learn Logix is a series of articles designed to teach you everything you need to know to work with Rockwell Automation’s Studio 5000 Logix Designer and the Logix 5000 series of PLCs.
In the last part of the series, we learned about the CompactLogix I/O modules and their features. You can find that part here or if you’re new to the series, you can find all of the previous parts here.
In this part of the series, we’ll look at the CompactLogix communication modules and their features.
The CompactLogix system has communication modules available that enable CompactLogix systems to communicate on many common industrial networks including;
Other communication modules, manufactured by third parties, allow ControlLogix systems to communicate with other manufacturers’ PLC systems too.
In the rest of this article, we’ll look at the features of one of the most commonly used ControlLogix communication modules — the 5069-AEN2TR EtherNet/IP communication module.
The 5069-AEN2TR communication module allows CompactLogix modules to communicate on an EtherNet/IP network.
The module is equipped with five status indicators. Specifically, these indicators are;
The OK indicator shows the overall health of the module.
A solid green LED indicates that the module is operating normally.
The SD indicator shows if the SD card is in use.
A blinking green LED indicates that the module is reading from or writing to the SD card.
The NET indicator shows the state of the EtherNet/IP port.
A solid green LED indicates that the module has an IP address configured and at least one active connection with another device.
The LINK1 and LINK2 status indicators show the status of the embedded Ethernet ports of the communication module.
A flashing green LED indicates that the module is communicating through the Ethernet port.
The 5069-AEN2T is very similar to the 5069-AEN2TR with the exception that it does not have the SD status indicator.
In this article, we learned about the CompactLogix communication modules and their features.
In the next part of the series, we will get an introduction to the Studio 5000 Logix Designer application, the software development environment for the Logix 5000 platform of controllers. If you haven’t already, be sure to subscribe to the mailing list below to be notified when the next part is available.
Update: You can find the next part of the Learn Logix series, Studio 5000 Logix Designer Overview, here. This article gives an overview of the Studio 5000 Logix Designer application, which is the development environment for the Logix 5000 platform, and introduces the most important components in a Studio 5000 Logix Designer project.
Learn Logix Part 4.5. In this article, we learn about the various operating modes available for Logix 5000 controllers and the programming operations available in each mode.
Learn Logix Part 4.4. In this article, we learn how to understand and fix abnormal device states in RSLinx Classic.
