Glossary
PLC
PLC is a general term for devices and systems with which the HMI device communicates,
e.g. SIMATIC S7.
PLC job
A PLC job triggers a function at the HMI device.
Process visualization
Denotes visualization of technical processes by means of text and graphic elements.
Configured plant screens enable intervention in runtime plant processes by means of data
input and output.
Project
A project is the result of a configuration using an engineering software. The project usually
contains several screens with embedded system-specific objects, basic settings and alarms.
The project is saved in the project file.
There is a difference between an offline project on a configuring PC and an online
executable project on an HMI device. A project can 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. However, on the HMI device you can only
transfer the executable project which has been generated specifically for this HMI device.
Project file
Source file from which the executable project file for the HMI device is generated. The
project file is usually not transferred and is retained on the configuring PC.
Project file, compressed
Compressed format of the project file. The compressed project file can be transferred in
addition to the executable project file to the corresponding HMI device. The upload function
must be activated accordingly on the configuring PC at the time of the transfer. The
compressed project file is usually saved to an external memory card.
A compressed project file has the extension *.pdz.
Project file, executable
An executable project file is generated from the project file for a specific HMI device in the
course of engineering. The executable project file is transferred to the associated HMI device
where it is used to operate and monitor plants.
