Number of Channels (NUMCHANS)
Channel Number Offset (CHANNUMOFFSET)
PDC Grouped (GROUPEDPDC)
For example, consider that two analog input modules are grouped and the slot 1 belongs to analog input
module 1 and slot 2 belongs to analog input module 2.
The PDC Grouped (GROUPEDPDC) parameter is indicated as "GREEN," and the Number of channels
(NUMCHANS) parameter can be modified.
Type the physical slot number of the PBHIOMB in the Slot Number (SLOTNUM) box.
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.
In the Number of Channels (NUMCHANS) box, type the number of channels to be associated with the
If you want to configure the PBHIOMB for slot 1, then type the slot number in the SLOTNUM box and
then type the number of channels in the NUMCHANS box.
In the HART Configuration tab, perform the following steps.
Type the process data index in the Directory Process Data Index (DIRPROCDATAINDEX) box.
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
Select the check boxes for the respective HART Enabled channels.
The channel name is automatically displayed in the Channel Name (CHNLNAME) column.
The Channel Name (CHNLNAME) can be edited only in the Project view.
The HART Enabled channels appear under the PBHIOMB block in the Project view.
To configure a PBHIOMB block for Universal Modules
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.
