Modbus Addressing
Each of the memory addresses in the CLICK (X1, DS1, etc.) has a unique Modbus address.
This means the network master in the Modbus network can access any memory address in
the slave CLICK PLUS PLC. The best way to check which Modbus address is assigned to a
particular CLICK memory address is to use the CLICK programming software.
Click the Program tab located in the Navigation window and double click Address Picker as
shown below.
After the Address Picker window opens, check the option Display MODBUS Address on the
right bottom.
Select the Program tab,
then double click
Address Picker.
These are the Modbus
addresses. The numbers in
the parenthesis indicate which
function codes can be used for
each memory address.
Check the option
Display Modbus
Address.
