Step 5: Click on the new Modbus Device in the Configuration tree at the
left of the screen. Locate the hyperlink at the lower right of the screen to
"Add Data Blocks" to the device. Select a name to be associated with the
function code. For example, if the device is remote I/O, name the I/O
Group “Outputs” for example. There is a seven-character limitation on the
I/O Group name. The Starting Address is dependent on the remote
device. Consult the documentation for the remote device to understand
the register offset required to access its functions.
Click on the Local Address Range link to enter the IEC Global variable's
address range for this I/O group. Enter the starting address and number
of elements. The used address ranges will assist the programmer in
deciding which IEC address to use as starting address.
