2.8
Easy to select a version of an instruction
The development and release cycles for certain sets of instructions (such as Modbus, PID
and motion) have created multiple released versions for these instructions. To help ensure
compatibility and migration with older projects, STEP 7 allows you to choose which version
of instruction to insert into your user program.
Click the icon on the instruction tree task card to enable the
headers and columns of the instruction tree.
To change the version of the instruction, select the
appropriate version from the drop
-down list.
2.9
Easy to drag and drop between editors
To help you perform tasks quickly and easily,
STEP
7 allows you to drag and drop elements
from one editor to another. For example, you
can drag an input from
the CPU to the address
of an instruction in your user program.
You must zoom in at least 200% to select the
inputs or outputs of the CPU.
Notice that the tag names are displayed not
only in the PLC tag table, but also are
dis
played on the CPU.
To display two editors at one time, use the
"Split editor" menu commands or buttons in
the toolbar.
