Changing the DTM
address via the Generic
Slave DTM
Example
1,2,3...
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.
The PROFIBUS Ident Number can be found in the Generic Slave DTM or
through the device's documentation. By default the device's current ad-
dress will be 126. If necessary, change this to the actual current address.
2. Enter the new device address in the New Address field.
3. Optionally, select the Lock checkbox, if the address change must be made
permanent.
4. Press the Set button to invoke the PROFIBUS DP Set Slave Address ser-
vice. The Status field will display the status of this service.
Selecting the Lock option makes any future changes of the address impossi-
ble, 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.
When assembling the PROFIBUS configuration in the Network view, the Mas-
ter 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.
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.
1. Open the Configuration User Interface for the slave device, by selecting it
in the Network view, and double-clicking the left mouse button.
2. Select the Station Address field at the top of the Configuration tab (see fig-
ure below) and change the value to 10.
