7 DEVICE SUPPORT BLOCK (DSB)

7.14 Configuring a device-specific DSB

The PROFIBUS devices such as the Turck Excom, CEAG, Siemens AS-i Link, and Siemens ET200M have
device-specific DSBs. You can use the device-specific DSB to configure these devices.
Tip

•
Prerequisites
• The PGM block and the Protocol Blockmust be defined.
• The PROFIBUS slave devices must be defined in the Field Network Configuration tab of the Protocol
Blocks.
Perform the following steps to configure a device-specific DSB
1 Drag-and-drop the DSB block from the DSB library to one of the Protocol Blocks.
The Load Dialog box appears.
Click OK.
2
The DSB block icon appears under the Protocol Blockto which it is assigned.
3 Double-click the DSB block.
The DSB block configuration form appears.
In the Tag Name box, type the name of the DSB (a maximum of 16 characters) or accept the default.
4
5 In the Item Name box, type the item name.
6 In the Description box, type a brief description (a maximum of 132 characters) of the block.
7 In the Byte Order list, select the byte order.
You can define the byte order in the little-endian or big-endian format.
8 In the Associated Asset box, click the
The Point Selection dialog box appears.
Select an asset from those configured in the Enterprise Model Database to set the Scope of Responsibility
9
(SOR) for the point.
No validation is done at the configuration time. If you enter an asset that does not exist in the points
database, the associated asset for the point reverts to the server point. If the asset does exist but is not an
area-enabled asset, then the first area-enabled asset up the tree is used for the SOR of that device. A
subsequent upload of that device point to Control Builder returns the area-enabled asset and not the original
non-assignable asset entered.
In the Slave Address box, type the address number of the slave device.
10
• The slave device address range is 2 through 125.
• This address must be identical to the address of the slave device defined during the field network
configuration.
• The DSB communicates with the slave devices through this address. The slave device address must be
unique for a Protocol Block.

You can use this procedure as a reference for configuring the DRIVEDSB.
The Siemens ET200MDSB is used for illustration purpose.
Attention
For DSB blocks, the State to Load and Post Load State conditions are not applicable. For more information on
loading control strategy components, refer to the Control Building User's Guide.
Attention
If you do not select the byte order, an error message "DSBByteOrderNotSelected" appears when you load the DSB
block.
