Glossary
TP 270, OP 270, MP 270B (WinCC flexible)
C-4 Operating Instructions, Edition 03/2004, 6AV6691-1DD01-0AB0
Operating element
A component part of a project used to enter values and trigger functions. A button, for
example, is an operating element.
PLC
A general term for devices and systems with which the HMI device communicates, e.g.
SIMATIC S7.
Process visualization
The representation of processes from the areas of production, logistics and services using
texts and graphics. Configured elements enable the data to be read from and written to
processes running on systems being monitored and, thus, to actively intervene in them.
Project
The result of a configuration using a configuration software. The project contains system-
specific objects, basic settings and alarms in the form of screens. The project is saved in the
project file with the file name extension *.hmi if it has been configured with WinCC flexible.
It is important to differentiate between the project on the configuration computer and that on
the HMI device. A project on the configuration computer can be available in several
languages than can be managed on the HMI device. The project on the configuration
computer can be set up for different HMI devices. Only the project set up for a particular HMI
device can be transferred to that HMI device.
Project file, compressed
The file which is generated and transferred to the HMI device when "Enable BackTransfer" is
enabled during configuration on the configuration computer.
Recipe
A combination of tags to a fixed data structure. The data structure configured can be
assigned data on the HMI device and is then referred to as a data record. The use of recipes
ensures that when a data record is downloaded, all the assigned data is transferred to the
PLC at the same time.
Remote on/off
An option in the "Loader" menu which enables and disables remote control of the HMI device
from the PLC.
Runtime software
Software for process visualization with which a project on a configuration computer can be
tested. Also refer to project and configuration software.
