This project property contains settings that describe changes in behaviour compared to
Versions 5.x and 6.0.
Setting Description
"Limit" event in "VarIn"
control element extended This setting relates to the occurrence of the "Limit" event in the "VarIn" control
element. The event occurs in the control element during input if a limit
monitoring function has been activated by means of the "LimitCheck" or
"UseItemLimits" properties. A choice between two kinds of behaviour is to be
made, especially if multiple−digit input values have to be checked:
l deactivated (compatible with Versions 6.0, 5.x): The "Limit" event occurs
immediately during input if the specified value exceeds the upper limit. If the
value is below the lower limit, the "Limit" event is prevented from occurring
until the input has been marked as completed due to a change of focus or due
to the Enter key being pressed. If the lower limit has been set to "20", for
example, the user can enter the value "23" by typing in the digits "2" and "3"
without triggering the "Limit" event.
l activated (standard behaviour with Version 6.1 and higher): If the lower limit
has been set to "20", for example, the "Limit" event is triggered when the user
enters the value "23" by typing in the digits "2" and "3". The event occurs
after the digit "2" has been entered because this value is below the lower
limit. This setting is applied in practice, e.g. by the entry of digits with the
on−screen keyboard (NumPad). In this context, an incomplete entry or an entry
that exceeds/falls below the limits is signalled by a colour.
"DecPoint" property writable
in the VisiWinNET item This setting relates to all VisiWinNET control elements that link−up an analogue
value as a "process variable" in the VWItem property. For the link−up of analogue
values, the "DecPoint" property is available within the "VWItem" property. The
function of this property is controlled by the "DecPoint Property" setting in the
VisiWinNET item:
l deactivated (compatible with Versions 6.0, 5.x): If the "UnitConversion"
property has been set to TRUE in the control element, "DecPoint" is inactive
during the runtime.
l activated (standard behaviour with Version 6.1 and higher): The displacement
of the decimal point as specified by means of "DecPoint" is also applied, if
necessary, to the unit conversion function activated by means of
’UnitConversion’. This means that decimal places in the case of numbers with
floating decimal points can be specified as well as conversion by means of a
unit class.
Optimised activation of
variables when a changeover
is made from one form to
another The variables needed on forms are reported together to the variables core once
the form has been completely loaded. This increases the page−changing speed
because the necessary variables for the associated communication channel are
activated (deactivated if no longer necessary) together and therefore faster.
However, a consequence of activating this option is that the value from the
communication channel is not always current in the first "Change" result of an
item (cause: ChangedByConfig) but may be an older value or the starting value.
Deactivation of this setting restricts the function of the following components:
l VisiWinNET.DataAccess.MultiItemActivator (implemented in
VisiWinNET.Standard.Client/ VisiWinNET.Compact.Systems)
l VisiWinNET.Forms.BaseForm (implemented in VisiWinNET.Standard.Forms/
VisiWinNET.Compact.Forms)
l In VisiWinNET SMART, the forms directly inherit from
"VisiWinNET.Forms.BaseForm". Here as well, deactivation of the setting
results in a functional restriction.
