# SLMP Settings via the Cognex Comm Card Configurator

Before SLMP communications can be established, the vision system must be configured to enable SLMP, using the SLMP tab of the Cognex Comm Card Configurator. This is used to configure the connection to the MELSEC Automation Controller (either FX series PLCs over Ethernet, or Q and L series PLCs over Ethernet, and CC-Link IE field gateways), and define the device addresses and sizes for the various data blocks.

The Cognex Comm Card Configurator can be accessed from Cognex Designer Launch Page > Utilities tab.
