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.
Select a), then enter Location: 0
0 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000
10 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000
20 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000
30 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000
40 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000
Note that I/O Image locations are specified in decimal, whereas register values are displayed and
specified in hexadecimal. If you want the 105G to stop the host device writing values to the I/O
database at the same time, then select option i) Disable Fieldbus Write Area.
Press “Enter” to go back to the menu.
Option b) Write Image Array
This option allows you to change the value of an I/O register in the Radio Interface.
To change the value of a register, select option b) write image array.
Enter the location, then the value to be written to the register – for example
b
Location: 12
New Value: 0xFFFF
Register values should always be written in hexadecimal format. If you want the 105G to stop
the host device reading or writing values to the I/O database at the same time, then select option
h) or i).
Options c), d) Enable/Disable Comms logging
These options allow logging and display of radio communications. Once enabled, the radio
communications that are displayed is the radio traffic in raw format (i.e. the raw data frame for
each received packet is displayed in hexadecimal format). To decode the meaning of each radio
data packet, configuration software can be used to decode the data frames.
