The online diagnostics menu is also referred to as the “Debug” menu. The Debug Menu
allows the Radio Interface (I/O Registers) to be viewed and modified to confirm the
operation of the radio network. These options may be used to check operation of outputs at
remote sites, and to check the values of inputs reported from remote sites. When the protocol
driver does
not
use the shared RS232/485 port (Ethernet, Profibus, DeviceNet, and Modbus
Plus) data is also exchanged with the fieldbus and the I/O Registers according to the
configured fieldbus mappings.
Option a) Read Image Array
Displays the I/O registers of the Radio Interface - the register values for a block of 50
registers are updated every 1 second. For example, to display the I/O Database value at
locations 0 to 49.

the I/O database at the same time, then select option i) Disable Fieldbus Write Area.
