Selecting the Slave DTM Address Assignment displays a list of DTMs
assigned to the PROFIBUS Master DTM, together with their Station address:
When assembling the network, the PROFIBUS Master DTM will automatically
assign a station address to each new slave DTM. The purpose of the Slave
DTM Address Assignment function is to allow the user to change the DTM
address of one or more devices, to make it the same as the actual physical
address of the device on the network.
In order to change an address perform the following steps:
1. Select the slave device in the list.
2. Enter the new address in the field Address in the lower right corner of the
window.
3. Press the Set button. The Status field will display the status of this service,
i.e. whether or not the slave device responded without error.
The Set Device Station Address function is provided for slave devices of
which the PROFIBUS address is not set through switches, but by using the
PROFIBUS DP Set Slave Address service. Slave devices which support this
service also provide a means to store the address in internal non-volatile
memory. In case this non-volatile memory does not contain an entry, the
slave device will assume the default address 126.
Note 1. The PROFIBUS DP Set Slave Address service is supported by the CS1/
CJ1W-PRM21 Units as of Unit version 2.0.
2. In order to be able to change a device's address, the CS1/CJ1W-PRM21
PROFIBUS Master DTM must be on-line.
Selecting the Set Device Station Address displays the window shown below:
