In order to change the address of a slave device perform the following steps:
1
Enter the device's current address and its PROFIBUS Ident Number.
2
The PROFIBUS Ident Number can be found in the Generic Slave DTM or through the device's
documentation. By default the device's current address will be 126. If necessary, change this to
the actual current address.
3
Enter the new device address in the New Address field.
4
Optionally, select the Lock checkbox if the address change must be made permanent.
5
Press the Set button to invoke the PROFIBUS DP Set Slave Address service. The Status field
will display the status of this service.
Precautions for Correct Use Precautions for Correct Use
Selecting the Lock option makes any future changes of the address impossible, even after
power-down/power-up of the slave device.
Note After successful completion of the address change, the device DTM address in the Network
view has to be changed as well.
 Changing the Slave DTM Address
When assembling the PROFIBUS configuration in the Network view, the Master DTM automatically
assigns addresses in ascending order to the slave DTMs. If the physical address on the slave
device differs from the DTM address, the DTM address must be changed to match that setting.
Changing the DTM address can be done in two ways.
• Change the DTM address through the Generic Slave DTM
• Change the DTM address through the Slave DTM Address Assignment table via the Master
DTM.
 Changing the DTM address via the Generic Slave DTM
The first option, using the Generic Slave DTM is illustrated in the example below.
Assume that the F150-PRT Vision system in the previous example, has an actual network address
of 10, instead of 4, which was automatically assigned. In order to change the network address of the
F150-PRT (or any other slave device), perform the procedure outlined below.
