4.6.8
Modified Data
The conditions that determine the transfer of modified data from the operating ter-
minal to the controller are preset by the user in the variable definition. The following
options are available, allowing the user to select the point of time at which the data
are transferred:
-
with the Enter key (standard)
-
with the +/- keys or the Enter key (Incremental Editor)
-
transfer continuously (upon modification), i.e. every intermediate status is trans-
ferred
In the Incremental Editor, every intermediate value is transferred.
The option to transfer continuously (upon every modification) is limited to values
that are within the defined limits. If a value is entered that is outside the upper and
lower limit, the operator will get a system message to this effect.
If a value with multiple digits is entered that
-
exceeds the upper limit
the digit entered most recently will not be transferred to the controller.
-
falls below the lower limit,
the previously valid value will be restored.
-
falls below the lower limit (until the last digit has been entered) and then exceeds
the upper limit (after the last digit has been entered),
the previously valid value will be restored.
4.6.8.1
Input Plausibility Check
The plausibility check is performed on every editable numerical variable. This re-
quires that an upper and lower limit is specified in the variable definition. These
limits are displayed in the corresponding output format. System messages are
generated when invalid values are entered. Further guidance can be found in the
chapters Editors and System Messages.

Graphics
4.7.1
Images
Any program installed by the user can be used by the programming software as a
server for images.
Images can principally be made use of in two ways:
1.) Using existing images: The images created in another program can be se-
lected. A copy of the source image will then be stored in the project data-
base and converted to a pixel graphics of the specified dimensions.
2.) Creating new images: The program to be used to create the new image can
be launched from within the programming system. Once the image has
been created, the server is exited and the image is stored in the project
database. To display the image in the programming system and on the op-
erating terminal, the image is converted into a pixel graphics of the specified
dimensions.
