Overview:

MQTT Engine by default blocks the ability to write to MQTT device tags.  This is to prevent accidental writes when running on production systems.  When developing it must be explicitly enabled in the gateway configuration.  This tutorial outlines that process. 

Enable Device Writes from Ignition:

Start by browsing to your Ignition Gateway's web UI and select 'Configure'.  The default URL is:  http://127.0.0.1:8088
