Description of SitrLRHA
Object name (type + number) and family
Type + number: FB 2633
Family: SitrLRHA
Application area of SitrLRHA
The block is used for the following applications:
● Interface block between the HART driver blocks of the Sitrans LR 200, Sitrans LR 250,
Sitrans LR 260 and Sitrans LR 560 modules (referred to below as Sitrans LR) for the user
program and for visualization
How it works
The SitrLRHA block prepares the process data received from driver blocks from a Sitrans LR
and makes the data available for further use in the user program and for visualization. Data
entered in the faceplate or via the block inputs is transferred to the Sitrans LR by means of
driver blocks.
The function block supports all PDM configurations of the up to four HART auxiliary variables
of the Sitrans LR.
NOTE
In the following, block parameters are identified e.g. by
PV/SV/TV/QV_OpScale
, where
the
PV_OpScale, SV_OpScale, TV_OpScale
and
QV_OpScale
inputs are meant for the
HART variables PV, SV, TV and QV.
Configuration
Use the CFC editor to install the block in a cyclic interrupt OB (OB30 to OB38). The block is also
installed automatically in the startup OB (OB 100). Moreover, to connect the I/O signals, it is
imperative to call the Pcs7AnIn driver blocks (cyclic data, 4 to 20 mA), FbAnIn (HART variables)
and PiDr64 (acyclic data) in the same interrupt OB and startup OB (OB100) before the
SitrLRHA block in each case. The
AcyclData
output structure of the PiDr64 block is
interconnected to the input with the same name of the SitrLRHA block.
