8 PROFIBUS HART INPUT/OUTPUT MODULE (PBHIOM) FUNCTION BLOCK
Number of Channels (NUMCHANS)
Channel Number Offset (CHANNUMOFFSET)
PDC Grouped (GROUPEDPDC)
The PBHIOMB that is associated to a PDC can be viewed from the PDC tab of the DSB configuration form.
The number of channels supported by the PDC is displayed in the HART Configuration tab.
Type the physical slot number of the PBHIOMB in the Slot Number (SLOTNUM) box.
In the HART Configuration tab, perform the following steps.
Type the process data index in the Directory Process Data Index (DIRPROCDATAINDEX) box.
Select the check boxes for the respective HART Enabled channels.
The channel name is automatically displayed in the Channel Name (CHNLNAME) column.
The HART Enabled channels appear under the PBHIOMB block in the Project view.
To configure a PBHIOMB block when PDC is 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 in which the PDC is grouped.
Once the PDCNAMEREF is selected the following parameters are updated automatically.
Slave Name (SLAVENAME)
Slave Address (SLAVEADDRESS)
Slot Type (SLOTTYPE)
PDC Description (PDCDESCRIPTION)
If the Slot Type (SLOTTYPE) parameter is displayed as "Analog output (AO)," then AO channel value must be
manually set as equal to or greater than 3.6 mA for establishing the HART communication for AO devices.
Directory Process Data Index (DIRPROCDATAINDEX) value must be taken from the device manual.
See the specific device manuals for the data. The DIRPROCDATAINDEX value can also obtained from
the GSD file
The Channel Name (CHNLNAME) can be edited only in the Project view.
