As described earlier, inputs and outputs to the logic must be “linked” to variables in the S 3 database for the
controller in which the logic resides. When the database is “browsed” to locate the desired variable for a LON
device, controller or memory location, a very large array of device “items” will be listed.
These items are listed in alphabetic order under each tagname in the database. Many of these items are
familiar, like the standard “fire & gas” device types “Fire Alarm”, “Lo Gas Alarm” etc. Others like “Neuron ID” and
“Firmware Version” are not.
In addition to the standard F&G alarms, each LON device and the controller itself have a great deal of additional
status and diagnostic information that can be utilized in logic. The following pages of this users guide provide
a reference to over 300 of these “Device Items” so that the programmer can determine whether they could be
used to enhance the user program being worked on.
