Template of SitrLuHA

This process tag type is used to connect a Sitrans LU HART with driver blocks to PCS 7.
Note
Since the APL driver blocks Or08, SelST16, Pcs7AnIn and FbAnIn are missing in the
library for licensing reasons, they must be copied into the library before the Sitrans LU HART
template is copied. For this purpose, create a new CFC in the library, open it, and position
the Or08, SelST16, Pcs7AnIn and FbAnIn blocks from the PCS 7 AP Library into the CFC
using drag-and-drop in order for the blocks to be copied into the library. The newly created CFC
can be deleted once this is completed.
The cyclic values are transferred by the PCS 7 standard blocks Pcs7AnIn (4 to 20 mA signal)
and FbAnIn (HART variables), the acyclic values are transferred by the PiDr64 block to and
from the device.
The process tag type contains the required interconnections between the blocks mentioned
above. If not all two HART variables are used, the unneeded driver blocks for reading the values
(PV and SV) can be accordingly removed from the template.
The PV_In inputs of the Pcs7AnIn (4 to 20 mA) and FbAnIn (PV and SV) blocks must be
interconnected with the corresponding input word or double word from HW Config for
instantiation of the template. The Laddr input of the PiDr64 block (AcyclicData) is
configured with the address of the 4 to 20 mA signal (not interconnected!).
The SlotHart input receives the slot number of the SITRANS LU module within the analog
input module at the Sitrans LU (SitrLuHA) block. The Feature bit 2 must be used to configure
whether communication with the module is by means of the HART protocol.
All required information can be found in HW Config.
Note
Correct configuration of the SlotHart input is a mandatory requirement and cannot be
checked by the block.
