GSV/SSV Objects

198
When you enter a GSV/SSV instruction, you specify the object and its attribute
that you want to access. In some cases, there will be more than one instance of the
same type of object, so you might also have to specify the object name. For
example, there can be several tasks in your application. Each task has its own
TASK object that you access by the task name.
You can access these objects.

ATTENTION: For the GSV instruction, only the specified size of
data is copied to the destination. For example, if the attribute is
specified as a SINT and the destination is a DINT, only the lower 8
bits of the DINT destination are updated, leaving the remaining 24
bits unchanged.
