Diagnostics
This chapter describes network diagnostic tools and information
available from the module’s Web-based configuration utility. To
access this utility, see “Connecting and logging on” on page 15 .
IO diagnostics
Click IO Diagnostics from the home page of the Web-based
configuration utility to read and write I/O store registers within
the module.
To read a register location, enter an address location (for example,
10001 for digital inputs), enter a count (number of consecutive
registers), and then click Read (see Figure 44 ). The returned address
location and the returned values appears at the bottom of the page.
To write to outputs, enter the address location, count, and value,
and then click Write . You will see the outputs change to the value
you entered. For example, write to Register 1 with a count of 8 and
a value of 1 will turn all the local digital outputs on. Write to Register
40001 with a count of 2 and a value of 49152 will set the two local
physical analog outputs to 20 mA.
otee: N
If the value “~“ appears at the bottom of the page when reading a
register, it indicates that the register has been initialized to the “Invalid” state
through the fail-safe configuration and therefore has no value (not even zero).
A mapping will only be sent when all registers have a value. To set
an initial value for registers upon startup, use the Fail-safe Block
Configuration menu in the Web-based configuration utility or use
the MConfig utility (see “Fail-safe blocks” on page 15 ). If there
is a mapping configured and any one of the source register values
has the value “~“ the mapping will not be sent (see “Invalid register
state” on
page 15
).
Using the I/O Diagnostics page, you can check the register locations
for the “~“ values and even write values if required. If you see the
value “3” when reading the status of the DIO on the module it
indicates that the DIO is being used as an output in the “on” state.

Register Register address location.
Count Number of consecutive registers, starting from the
register location specified in the Register field.
Value Value to be written.
Read To read a register location, enter an address location
(for example, 10001 for digital inputs), enter a count
(number of consecutive registers), and then click Read .
Write To write to outputs, enter the address location, count,
and value, and then click Write .
Watchdog error log
The module uses a various processes to control aspects of its
internal functions, such as radio operation, I/O functionality, and
Modbus communications. Each process runs independently, and
can interact with the other processes to provide a robust wireless
I/O product.
All processes are monitored by an internal “watchdog.” If a
processes has a problem and stops running, the watchdog will
identify the problem and restart the module. The watchdog also
creates a text file showing which process had the problem.
This text file is stored in a directory called ”dog” off the main root
IP address of the module. To display this text file in your browser,
enter http://<Device IP Address>/operator/.
If the watchdog directory continues to show text files, it may
indicate a problem with the module or its configuration. If this
happens, save the module configuration (see “System tools” on
page 28
) and the list of watchdog files, and then contact Eaton
technical support.
The following table describes the different watchdog processes.

Module information registers
Certain registers in the module show modules characteristics, such
as the serial number, firmware version, and so on. This information is
available on the home page of the module’s Web-based configuration
utility. However, having the information available in registers allows
a host system to read the values via Modbus, if Modbus has been
activated.
•
Register 30494, 30495 and 30496 = Module serial number
•
Register 30497, 30498 and 30499 = Module firmware version
•
Register 30500 = Firmware patch level
