The DSB communicates with the slave devices through this address. The slave device address must be
unique for a Protocol Block.
For GENPADSB, the transparent segment coupler displays all devices connected to the PROFIBUS PA
network as if they were PROFIBUS DP field devices.
For GENPAGWDSB, the PROFIBUS DP/PA link, Siemens DP/PA link IM-157, is a DP slave that acts as a
proxy for the PA field devices. The DP/PA Link reserves one PROFIBUS DP slave address.
In the Device Type box, type the description of the device type.
In the Connection Break TimeOut (Sec) box, type the duration in seconds during which the network
communication break needs to be filtered off.
If the communication break condition persists even after this time, then the status of the slave device is set to
"Communication Error." This parameter is applicable only when the slave device is disconnected from the
Profibus network. If the complete Profibus network is down, the status of all slave devices is set to
"Communication Error" immediately.
Select the Connection Break Timeout applicable for Network Down check box if you want the output
channels to initialize back from the user-defined values after the connection break timeout timer is exceeded.
If the complete Profibus network is down and you have not selected this check box, the status of all slave
devices is set to "Communication Error" immediately.
However, if you have selected this check box and the complete Profibus network is down, the status of all
slave devices are set to "Communication Error" after the connection break timeout is exceeded.
Select the Reset counters check box if you want to reset all static counters.
Click the Slave Status tab.
The Slave Status tab displays the slave communication standard status bits and extended diagnostic information in
the Monitoring view. .
Click the Alarms tab.
The Alarms tab is only applicable to the Generic DSBs and the DRIVEDSB as you can configure alarms
only for these DSBs.
Click the PDC tab.
The PDC tab of the DSB block is used for defining the PDCs. You cannot proceed with the DSB configuration
until you complete the PDC configuration. To configure the PDCs, see section Configuring the PDC tab.
Use the online help as a guide to complete the configuration entries on all other tabs.
