Linux Development Module for CompactLogix™


The MVI69E-LDM module allows users to develop and deploy C/C++ custom algorithm applications for CompactLogix™ systems. Users are also able to create drivers for specialty Ethernet and Serial end-devices. The Linux Development module comes with a built-in API for backplane communications to the processor.

With the separate Development Kit, you are the developer who controls exactly what this module can and cannot do.

Check out a real-world example using this solution: Solving Ship's Communication Issue.
