Operating Modes
The following refers to the operating modes of Excel 500
controllers into which controller firmware version 2.04.xx
has been downloaded.
It is important to remember the following definitions:
Local: The term "local" refers to an operating mode in
which a max. of 16 Distributed I/O modules are connected
to a single host Excel 500 controller via a L
and in which no other devices co-exist on that bus. In this
mode, the Distributed I/O modules are assigned to their
host Excel 500 controller automatically, and autobinding is
performed.
Shared: The term "shared" means that, aside from the host
Excel 500 controller and its Distributed I/O modules, other
devices (which may include other Excel 500 controllers with
their own Distributed I/O modules, Excel 50 or Excel 10
rd
controllers, or 3 -party devices) co-exist on the L
bus. In the shared mode, autobinding may still be used for
the NVs of a max. of 16 Distributed I/O modules assigned
(manually) exclusively to the host Excel 500 controller.
NOTE: It is recommended that you use CARE to assign
the Distributed I/O modules to the host Excel 500
controller (i.e. to enter the Distributed I/O modules'
Neuron IDs). The alternative is to assign them
using the MMI.
Open: The term "open" refers to an interoperable
L W system in which CARE has been used to
ON ORKS
generate a L M -compliant network interface file

capable of providing NVs which can be bound to other
devices (which may include other Excel 500 controllers with
their own Distributed I/O modules, Excel 50 or Excel 10

controllers, or third-party devices). In the open operating
mode, the NVs of the Distributed I/O modules exceeding 16
must be bound manually using a L
management tool (an LNS-based tool capable of using
Honeywell plug-ins is recommended).
Shared/Open: The shared and the open operating modes
can be in effect simultaneously. In this case, autobinding is
performed for the NVs of a max. of 16 Distributed I/O
modules, while the data points of additional Distributed I/O
modules must be mapped with shared NVs, and the NVs of
the additional Distributed I/O modules must be bound
manually (e.g. using an LNS-based tool).
Autobinding
The following refers to the autobinding of the NVs of
Distributed I/O modules to Excel 500 controllers into which
controller firmware version 2.04.xx has been downloaded.
When Distributed I/O modules are used exclusively by
Honeywell Excel 500 controllers, it is possible to auto-
matically bind their NVs to the controller. This is referred to
as "autobinding." In autobinding, each controller on the bus
finds the Distributed I/O modules assigned to it and binds
the required NVs.
IMPORTANT:
Autobinding does not work across routers. Dis-
tributed I/O modules must be located within the
same router segment as the controller to which their
NVs are to be bound. However, autobinding is
possible across repeaters.
