Linux Development Module for ControlLogix


The MVI56E-LDM is a powerful in-chassis edge module. It allows users to develop and deploy custom applications for ControlLogix® 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. The LDM library includes sample applications (with source code) for Sparkplug B MQTT, standard MQTT and Thingworx, which allows users to customize their IIoT (industrial Internet of Things) applications. With the separate development kit DVD, you as the developer control what this module can and cannot do!
