SITRANS P
10.1 SitransP
supported by P420. If HART communication is used, reading out of the module configuration
can be triggered in the WinCC faceplate. Otherwise, the physical variable of the 4 to 20 mA
signal (PV_Meas0 input), its unit (PV_Unit0 input), and its scaling (PV_OpSacle input) must
be entered manually.
Note
Correct configuration of the SlotHart input is a mandatory requirement and cannot be
checked by the block.
The maximum and minimum values for the alarm and warning limits of the limiters 1 to 3 are
parameterized at the inputs L1/2/3_Scale. If the Feature Bit7 (synchronize alarm
configuration with module) is set, the measuring range limits available in the module are written
to the corresponding L1/2/3_Scale inputs when reading the configuration data. P420 does
not support this feature.
The SITRANS library contains a template for process tag types as an example with an
application scenario for the SitransP block, Template of SitransP (Page 398)
Note
The APL blocks ChkREAL (FC260) and SelST16 (FC369) that are not supplied with the
SITRANS Library are called internally by the SitransP block. If these two blocks are not yet
installed in your project, copy them from the APL library to your project before you download the
project to the controller.
Note
The user text library "SitransP_MeasVal" must be copied from the Sitrans Library to the PCS
7 project prior to the OS compilation. To do this, open the SITRANS Library from the Simatic
Manager using File -> Open... -> Libraries. Copy the "SitransP_MeasVal" file from the library
(directory: Blocks+Templates\Text Libraries) into a user text library folder created using the S7
program in your PCS 7 project.
Startup characteristics
Use the Feature Bit Setting the startup characteristics (Page 50) to define the startup
characteristics of this block.
The messages are suppressed after startup for the number of cycles set at RunUpCyc.
Status word allocation for Status1 parameter
You can find a description for each parameter in section I/Os of SitransP (Page 379).
