Digital templates

If the properties of a digital template are altered when the template has already been used for one or more objects, the changes will affect these objects.

The following rules apply:

Bit pattern, logic, choice of single bits as well as state and command names (that is, everything on the Bit Map I/O and Alarm In/Ack Bit tabs) change the previously defined objects. The state and command names can be changed without it being necessary to redefine the previously entered objects.
Scan and base intervals, etc. (everything on the Data Management Definitions tab) do not affect already defined objects.
Changes in the PLC addressing do not affect previously defined objects.
Alarm numbers for the individual objects, which are not modified in relation to what the template indicates, are changed. Already modified alarm numbers are not changed when the numbers in the templates are.

Analog, table and counter templates

The properties of a table, counter or analog template may be changed when the template is used to create the individual objects. Previously defined objects are NOT affected by later changes to the templates.
