Slave Unit Address Duplication Error
In any of the following cases, a Slave Unit address duplication error will occur and the Address Duplica-
tion Error Flag (status bit 03) will turn ON for the Slave Unit that joined the network later.
At the same time, the NS indicator on the front of the Gateway Unit will flash red and the seven-seg-
ment display will show "d0." Remote I/O communications will not stop.
• There is another Slave Unit for which the same node address is set.
(For example, both Slave Units are set to node address N.)
Note: An address duplication error will occur if the same node address is set for two Slave Units in the same allo-
cation area. This applies only if both are Input Slave Units or both are Output Slave Units.

• Different node addresses are set, but the allocated memory areas overlap.
(For example, a Slave Unit that is set to node address 0 has 24 inputs and a Slave Unit that is set to
node address 1 has 16 inputs. In this case both Slave Units will be set to use the Input 1 Area.)
Note: As long as the allocated areas themselves are not duplicated between nodes, Slave Units set for different
node addresses can be allocated remote input registers (RWr) and remote output registers (RWw) in the
same node address area.
(For example, a Slave Unit set for node address 1 can be allocated 16 outputs in the Output 1 Area, while an
Expansion Slave Unit set for node address 0 can be allocated 16 inputs in the Input 1 Area.)
• A Slave Unit was removed and then a Slave Unit of a different type started participating at the same
node address.
• CompoNet communications become unstable.
Illegal Configuration Error
If the permitted number of Repeater Unit segments is exceeded, the NS indicator on the front of the
Gateway Unit will flash red and the seven-segment display will show "E5."
