Source file
File from which various project files can be created, depending on the configuration. The
source file is not transferred and remains on the configuration computer.
The file name extension of a source file is *.hmi. Refer to Source file, compressed and
Project file.
Source file, compressed
Compressed form of the source file. Can be transferred in addition to the project file to the
corresponding HMI device. "Enable Upload" must be set in the project on the configuration
computer. The file extension of a compressed source file is *.pdz. The standard memory
location for a compressed source file is the external MMC. Refer to Source file.
To restore a source file, it is necessary to use the same WinCC flexible version which was
used to configure the project.
STEP 7
Programming software SIMATIC S7, SIMATIC C7 and SIMATIC WinAC controllers.
STEP 7 Micro/WIN
Programming software for controllers of the SIMATIC S7-200 series.
Symbolic IO field
Box for the input/output of a parameter. Contains a list of default entries from which one can
be selected.
System alarms
Assigned to the "System" alarm class. A system alarm refers to internal states on the HMI
device and the controller.
Tab order
In the configuration, this sets the sequence in which objects are focused on pressing the
<TAB> key.
Tag
Defined memory location to which values can be written to and read from. This can be done
from the controller or the HMI device. Based on whether the tag is interconnected with the
controller or not, we distinguish between "external" tags (process tags) and "internal" tags.
Transfer
The transfer of an executable project to the HMI device.
