• Slave Address (SLAVEADDRESS)
• Slot Type (SLOTTYPE)
• PDC Description (PDCDESCRIPTION)
• PDC Number
• Number of Channels (NUMCHANS)
• Channel Number Offset (CHANNUMOFFSET)
• PDC Grouped (GROUPEDPDC)
8 Type the physical slot number of the PBHIOMB in the Slot Number (SLOTNUM) box.
You must type the correct slot number since the number of channels is displayed based on the slot number.

8.4.1 Configuring a PBHCHANNEL block

Prerequisites
• DSB for the PROFIBUS slave module is created and configured.
– HART-enabled modules must be configured in the DSB.
• HART Device Description (DD)-based template is already created in the Library.
• PBHCHANNEL block is created under the PBHIOMB block.
To configure a PBHCHANNEL block
1 From the Project view, double-click the PBHCHANNEL block.
The PBHCHANNEL configuration form appears.
In the Main tab, perform the following steps.
2
Select the device template from the Configured AI HART Device (HCFGDEVAI) or Configured AO

Attention
The NUMCHANS and CHANNUMOFFSET parameters are updated based on the type of associated
PDCNAMEREF.
If the selected PDC is an input PDC, then the NUMCHANS parameter is set as 2 and the CHANNUMOFFSET is
set as 0.
If the selected PDC is an output PDC, then the NUMCHANS parameter is set as 6 and the CHANNUMOFFSET
is set as 2.
Note
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
Note
The Channel Name (CHNLNAME) can be edited only in the Project view.
