Double-Mapping a Data Point
It is possible to preserve the autobinding by mapping the
data point with a second NV. However, the second NV
must then be bound (using a L
ment tool) to another L W
ON
preserves autobinding, it does require one controller NV
more than if all binding is performed using a L
network management tool (e.g. LonMaker).
Binding to Other Devices
If you wish to bind the NVs of Distributed I/O modules to
other devices (i.e. other than the host Excel 500 controller),
autobinding cannot be used. Instead, you will have to
employ a L W network management tool (e.g.
ON ORKS
LonMaker) to (manually) bind all of the Distributed I/O
modules' NVs.
Troubleshooting (Controller Autobinding)
Wiring Check
NOTE: In the case of CARE 4.0, the controller cannot be
used to perform autobinding. However, you can
use XILON to perform the wiring test.
In the case of Excel 500 controllers with controller firmware
version 2.04.xx, Distributed I/O modules can be checked
out without even having an application loaded in the
controller. This is possible using a special test mode
previously active only for internal I/O modules. This test
mode, accessible through the "Data Point Wiring Check"
option on the second screen of the start-up sequence,
allows manually setting outputs and reading inputs to verify
the I/O wiring. The procedure is described in detail in the
XI581/582 - User Guide (Product Literature No.: EN2B-
0126GE51).

2. Switch the power ON / OFF.
3. Set the rotary HEX switch to an unused address for a
few seconds and then select the correct address. This
will reset the Distributed I/O module.
Please contact Honeywell if the above actions do not solve
the problem.
