Standard Mode
The standard mode is the mode of operation in which the terminals are most com-
monly used and that provides the highest performance. In this mode of operation,
the terminals act as intelligent peripheral devices for the controller by performing
controlled pre-processing of the visualization data, thus completely relieving the
connected controller of all operating tasks. This reduces the programming effort
required by the user, the run time and memory required in the PLC.
Communication processors have been dispensed with in the PLC and program-
ming unit interfaces have been used throughout, making the PLC connection very
economical. The operating concept is a universal one, thanks to the large number
of supported protocols. Operation of the machine has been made independent of
the type and manufacturer of the controller.
The standard mode is supported by every operating terminal. The system’s flexi-
bility means you can customize all menus and dialogs according to your particular
application. Extremely sophisticated operator guidances can be configured with
the aid of masks, system variables and control and function keys. In standard
mode, all functions which can be executed with the terminal, mask contents, texts,
messages and variables are stored in the user description (mask definition). After
the programming phase is complete, the user description is stored in the operating
terminal’s Flash memory.
In the description which follows, the term ‘
user’ refers to individuals who configure
or program the operator interface, while ‘
operator’ refers to individuals who monitor
and operate the data of the installation on site.
4.1
Setting the Operating Mode
The standard mode of operation can be set with the user-mode switch. Turn off the
terminal before selecting the mode of operation.
All terminals are factory-set to the standard mode.
The ON/OFF positions on the mode selector switch are marked.
The selected mode of operation becomes active as soon as power is supplied.
