User-set Allocation The Configurator can be used to set the Communications Unit node number,
first word, and number of bytes to allocate (allocation size) for input block 1
and 2 and for output block 1 and 2, as shown in the following diagram.
Output block 1 or 2: Output bits in the order I/O Units are connected on
the I/O Unit interface
Input block 1 or 2: I/O Unit interface status (two words), and input bits in
the order I/O Units are connected on the I/O Unit
interface
Example: CVM1/CV Series
Output block 1 or 2
