12-1 EAGLE QUANTUM PREMIER DEVICES
Version 6.0
Controller
Note
this Section is dedicated to the eQP controller and key field devices it supports. Please be aware that
the controller will encounter compatibility issues with some field devices if it’s firmware is not up to date
and does not match the correct version of the S 3 software. Refer to marketing bulletin 78-1006 for more
information.
The “Controller” is the first device on any Eagle Quantum Premier Local Operating Network (LON). This device
is used to perform the user logic, it provides the NFPA-72 required operator interface elements and provides a
communication interface to the S 3 Operator Interface Station (OIS) and/or other intelligent systems for monitoring
purposes.
Both the user logic and the configuration for all of the LON devices is first created and stored in the S 3 configuration
database, then downloaded to the Controller, which in turn downloads this information to the field devices where
it is stored in their non-volatile memory. A copy of the configuration data is also stored in the Controllers own
non-volatile memory.
When an Eagle Quantum Premier port is first created, the LON schematic is empty except for a “node rectangle”
representing the Controller, as shown in the example to the right.
The node rectangle is divided in half horizontally with the tag name in the top
and controller configuration in the bottom. In the example to the right, S 3 has
assigned “T1” as a temporary tag name. This tagname is randomly generated
and can be replaced by the user assigned tag name. The bottom half will contain
the controller configuration default of “Single” signifying a single “non-redundant”
arrangement.
