Node address settings
<(Set by the address setting dials (1) C)>
The address of a ProfiBus-DP slave station is set using the left rotary switch “ADRS.H” and right rotary switch
“ADRS.L” of the station module, as shown in (1).
These rotary switches set the node address of the applicable controller.
Each of these two switches can be set to a desired value in a range of 0 to 9.
Set the switches by following the address assignment rule below:
Node address number = (Rotary switch “ADRS.H” x 10) + (Rotary switch “ADRS.L” x 1).

Note 1) When setting ProfiBus-DP station numbers, remember that the ProfiBus-DP master station is always
assigned station number 0. Accordingly, numbers 1 to 99 are available for slave stations.
Note 2) The node address of each slave station set above cannot be changed while the slave is
communicating with the master.
