Various Editors are available in I/O masks for the various data types. With the term
Editor, we refer to program parts designed to provide a convenient method of ed-
iting input variables. This sequence control required for the editing process is com-
pletely integrated into the terminal. An additional 'software' in the controller is not
required for this purpose.
The Editors are influenced by the:
- data release (particularly from the connected controller)
- cyclic value refreshing
- the help system and
- the plausibility check.
The Editors are operated with the aid of editing and control keys. For details on the
respective functions consult the corresponding Editor description.
The variables of the controllers can be modified using the Editors. Upon entry, the
numerical variables are checked for plausibility. The limits are determined by the
user in the variable definition. It is also possible to include a variable-specific help
text. This text may, for example, provide a description of the variable function and
its valid range of values.
Variables are entered as follows:
The Data Release key will allow the Editor to be activated if the I/O mask contains
an editable value. When in the editing mode, the status LED in the Data Release
key lights up and the cursor points at the first editable variable. This value can now
be edited by using the numerical keyboard and/or the Plus/Minus keys. The value
is stored by pressing the Enter key. The value is checked for plausibility during this
process. If an error is detected, the status LED in the Help key will begin to flash.
A flashing status LED in the Help key indicates a malfunction to the user. A descrip-
tion of the malfunction will be displayed if the Help key is pressed. In the case of an
error, the Enter key can not be used to exit the editing field.
The control keys, on the contrary, can be used to exit an editing field even if the
value is invalid. In this case, however, the last value which was entered will be
discarded and the old value (original value) will be restored.
In the editing mode, control keys can be used to select editable variables. If the
Data Release key is pressed again, the editing mode will be exited and the status
LED will go off.
The following Editors are currently available for selection in the variable definition:
The functions of the keys are identical for all numerical Editors.
