Process visualization
Visualization of technical processes by means of text and graphic elements. Configured
plant screens allow operator intervention in active plant processes by means of the input and
output data.
Project
Result of a configuration using a configuration software. The project normally contains
several screens with embedded system-specific objects, basic settings and alarms. The
project file of a project configured in WinCC flexible is saved under the file name
extension *.hmi.
You need to distinguish between a project on the configuring PC and that on an HMI device.
A project may be available in more languages on the configuring PC than can be managed
on the HMI device. The project on the configuring PC can also be set up for different HMI
devices. Only the runtime project that has been generated for the respective HMI device can
be transferred to it.
Project file
File generated from the runtime project file for use on the HMI device. The project file is
normally not transferred and remains on the configuring PC.
The file name extension of a source file is *.hmi.
Project file, compressed
Compressed format of the project file. The compressed project file can be transferred
together with the runtime project file to the respective HMI device. For this purpose,
backtransfer must be enabled in the project on the configuring PC. The compressed project
file is normally stored on an external memory card.
The file extension of a compressed file is *.pdz.
Recipe
Combination of tags forming a fixed data structure. The data structure configured can be
assigned data on the HMI device and is then referred to as a record. The use of recipes
ensures that all the assigned data is transferred synchronously to the PLC during the
transfer of a record.
Runtime project file
File generated from the project file for a specific HMI device. The runtime project file is
transferred to the corresponding HMI device and used to operate and monitor plants.
The extension of a compressed file is *.pdz.
Runtime software
The runtime software is a process visualization software used to test a project on a
configuring PC.
