The CompactLogix Communication Modules

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;

  • EtherNet/IP
  • ControlNet
  • DeviceNet
  • FOUNDATION Fieldbus
  • Data Highway Plus
  • Remote I/O
  • HART

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.

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;

OK

The OK indicator shows the overall health of the module.

A solid green LED indicates that the module is operating normally.

SD

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.

NET

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.

LINK1 and LINK2

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.

5069-AEN2TR EtherNet/IP Communication Module

The 5069-AEN2T is very similar to the 5069-AEN2TR with the exception that it does not have the SD status indicator.

Conclusion

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.
