with the Block operation. The function keys which are within the BLOCK
hierarchy are shown in Figure 8-3 and are described in the paragraphs
following.

NOTE: If you exceed the allocated memory size when manipulating blocks of
ladder logic, an error message will result. To complete the BLOCK
operation, you may have to first reconfigure the memory size to allow the
operation. See Section 4 for information on configuring memory size.
Pressing the BLOCK function key displays function keys labeled as shown
and described below.
NOTE: The PUT function key will only be available when the VPU200 is in
the Offline mode of operation.
