System
The term
“ System” refers to registers defining the characteristics of the entire circuit board. System
registers report the same value independent of the slave address. Under BACnet structured view the
system points are grouped together.
Configuring Element and Channel Register for Service Types
The ViewPoint HD software enforces all element configurations to form a valid electrical system.
Configurations performed by remote systems may produce unexpected results if configurations are
internally inconsistent. The following tables document how to configure element and channel registers for
each service type. Every register should be explicitly written.
Red Text indicates Required Values, Purple Text indicates Suggested Defaults, if this data is not known.
