8.4 Configuring a PBHIOMB block
DSB for the PROFIBUS slave module is created and configured.
HART Device Description (DD)-based template is already created in the Library.
PDC grouping can be performed in the DSB, as applicable.
If you configure the PBHIOMB for universal modules, then you must need more than one PBHIOMB blocks since the
universal modules contain configurable channels, which can be configured as Analog Input or Analog Output. For
example, if a universal module contains eight channels, then the first two channels can be configured as "Analog input
channels" and the remaining six channels can be configured as "Analog output channels."
To configure a PBHIOMB block when PDC is not grouped
Click File > New > I/O Modules > PGM_IF > PBHIOMB.
When you create a PBHIOMB, it resides in the Unassigned folder in the Project tree. You must drag-and-
drop it to the DSB.
(Optional) Perform the following steps.
Drag-and-drop the PBHIOMB from the PGM_IF library to the DSB that is assigned to a PBLINK.
The Name New Function Blocks dialog box appears.
In the Destination column, you can accept the default name or modify the name, if required and then
The PBHIOMB block appears under the DSB block.
Double-click the PBHIOMB.
The PBHIOMB block configuration form appears.
In the Tag Name box, type the name of the PBHIOMB (a maximum of 16 characters) or accept the default.
In the Item Name box, type the item name.
In the Description (DESC) box, type a brief description of up to 132 characters.
Click the point picker to configure the PDC Name Reference (PDCNAMEREF) and then select the
associated HART-enabled device that is configured in the DSB block.
Once the PDCNAMEREF is selected the following parameters are updated automatically.
Slave Name (SLAVENAME)
Slave Address (SLAVEADDRESS)
Slot Type (SLOTTYPE)
PDC Description (PDCDESCRIPTION)
The PDC Name Reference parameter can be configured only if the PBHIOMB is assigned to the DSB.
Only PDCs of the DSB to which the PBHIOMB block is associated are listed in the point picker dialog box.
The PBHIOMB can be associated only to the following DSBs that follows the RIO profile.
