Two rotary switches (refer to the following illustration and table) are located on the

rear panel of the CPU. They are used for setting Modbus Plus node addresses for

SW1 (the top switch) sets the upper digit (tens) of the address; SW2 (the bottom

switch) sets the lower digit (ones) of the address. The illustration below shows the

correct setting for an example address of 11.

The following table shows the node addresses of the SW1 and SW2 switches.

SW1 and SW2 Switches

1 ... 9 0 1 ... 9

10 ... 19 1 0 ... 9

20 ... 29 2 0 ... 9

40 ... 49 4 0 ... 9

50 ... 59 5 0 ... 9

60 ... 64 6 0 ... 4

Note: If "0" or an address greater than 32 is selected, the RIO module displays a

flashing Error A and Error B LED to indicate an error condition. Only addresses 1-

32 are valid.
