You can find general information about the "On" mode in the On chapter.
"Out of service"
You can find general information about the "Out of service" mode in the Out of service section.
The descriptions of the operating modes are identical for the SitrLuHA and the APL; refer to the
online help for the standard APL blocks for information on them.

Functions of SitrLuHA

The functions for this block are listed below.
Configuration data
The configuration data comprises units, configuration of the 4 to 20 mA signal and HART
variables, scaling of the 4 to 20 mA signal, and the diagnostics values. After a change is made
in the device, reading of configuration data must be triggered with "Read configuration data" in
the parameter view of the faceplate. If the parameters were read back before a complete
download to the PLC, the configuration does not need to be reloaded from the device.
The SitrLuHA function block has the following configuration data which can be read out of the
Sitrans LU by means of the "Read configuration data" command:
Description
Configuration of PV, SV inputs
Vessel form
Units PV, SV
Scaling 4 ... 20 mA signal
Diagnostics values
Note
If the module is used without HART communication, the inputs must be parameterized
accordingly manually since reading out of the configuration from the module is not possible.
