•Slaves that require two words can be allocated two words using only one node address so that the next node addresses can be set for another Slave.

•Remote I/O words can be allocated in sequence regardless of the order of the node addresses.

Note The Configurator uses one node address. Therefore, the number of Slaves that can be connected is reduced if the Network is to be operated with the Configurator still connected. The Configurator can be removed, however, after the words have been allocated, and then another Slave can be connected to the Network in its place so that the number of Slaves that can be connected is not reduced.

Words are freely allocated to the Slaves and I/O blocks can be set as desired. Each node must be allo- cated at least one byte (leftmost or rightmost). If a Slave requires more than one input or one output word, then it can be allocated more than one input or output word. If a Slave requires less than one word, it will use either the rightmost or leftmost bits in the word allocated to it.

DFree Allocation Restrictions

The following restrictions apply when freely allocating remote I/O.

•The remote I/O allocated to one Slave cannot be separated, i.e., all input words must be consecutive, as must all output words. Inputs and outputs, however, can be separated.

•With a Slave requiring more than one word, a series of allocations cannot be started from the leftmost byte of the remote I/O. The leftmost byte, however, can be allocated to a Slave requiring only 8 bits.

•Multiple words cannot be allocated as the remote I/O for a single Slave.

•A Slave cannot be assigned to more than one Master Unit.

4-1-2 Scan Lists

HThe Scan List

Scan lists record information in the Master Unit on the Slaves that are connected to them. If the scan list is enabled, the information on each Slave is recorded, and can be used to determine normal Compo- Bus/D communications. The scan list provides the following information on each Slave.
