EAGLEHAWK NX CONTROLLER – INSTALLATION & COMMISSIONING INSTRUCTIONS
Addressing Panel Bus I/O Modules
Each Panel Bus I/O Module must be addressed manually
using its HEX switch (S2). The HEX switch setting is defined
using the COACH NX engineering tool.
PANEL BUS I/O MODULE
(EXAMPLE)
Fig. 38. Location of HEX switch on Panel Bus I/O Module
NOTE: A HEX switch setting of "0" corresponds to an
address in COACH NX of "1," a setting of "1" cor-
responds to an address of "2," and so on.
During commissioning, a max. of 16 Panel Bus I/O Modules
of each type (AI, DO, etc.) can be assigned addresses. In
doing so, no two modules of the same type (e.g., no two
Analog Input Modules, no two Digital Output modules, etc.)
may be assigned the same address. See also Fig. 39.

Failing to observe this requirement will cause a "Fail [date]
timeout" error message to appear in the "Health" column, and
the device status "down" to appear in the "Status" column.
This same error message will likewise appear if an address is
assigned to a module with which the controller cannot, for any
reason (e.g., due to defective wiring, or because the module
has not been physically installed, etc.), communicate.
Automatic Updating of Panel Bus I/O Module
Firmware
The firmware of the Panel Bus I/O modules is part of the
EAGLEHAWK NX firmware. The EAGLEHAWK NX controller
will thus automatically update the firmware of the Panel Bus
I/O modules as soon as it detects an older version in them.
Cable Specifications
Panel Bus I/O Modules
When checking the length of the power supply cable, the
connection cables to all Panel Bus I/O Modules must be
taken into account.
