6.9.5 Reviewing Plus+ Site Layout Discrepancies
For the controller to be functional the site layout will need to be fully completed i.e. the Nodes’
serial numbers will need to have been added to the configuration. It is recommended that this
is completed before importing the Plus
+
Site Layout, by using the ‘Installation App’. Refer to the
ST950 Plus+ Installation App Quick Start Guide (667/HQ/53000/300)
Discrepancies between the Plus+ Site Layout and the discovered Plus+ equipment can be reviewed
using the Status and Configuration → Plus+ → Discrepancy Report web page.
