Description of SitransP
Object name (type + number) and family
Type + number: FB 2627
Family: SitransP
Area of application of SitransP
The block is used for the following applications:
● Interface block between the driver blocks of the SITRANS P300, P310, P410, P420, P500
and P DSIII modules (referred to below as SITRANS P) for the user program and
visualization
How it works
The
SitransP
block prepares the process data received from driver blocks from a SITRANS P
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 P by means of
driver blocks.
The function block supports display of the 4 to 20 mA signal, the HART variables and the slave
pointer according to the configuration of the SitransP. The 4 to 20 mA signal, and not the first
HART auxiliary variable PV, is always used as the process value if both contain the same
physical variable.
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 (OB100). Moreover, to connect the I/O signals, it is
imperative to call the driver blocks Pcs7AnIn (cyclic data, 4 to 20 mA), FbAnIn (HART variables)
and PiDr64 (acyclic data) in the same interrupt OB and startup OB (OB100) before the SitransP
block in each case. The output structures
SxRdReq
,
SxWrReq
and
Para
of the SitraPDr block
are interconnected with the input structures of the SitransP block.
The
SlotHart
input receives the slot number of the SITRANS P within the analog input
module. The
Feature
bits 2 to 6 must be used to configure whether communication with the
module is by means of the HART protocol and, if applicable, which HART variables are used.
Feature
bit 7 = TRUE means that the block takes over the alarm configuration including limits
when reading the configuration data from the device. Reading out the alarm configuration is not
