for Mixed Slave Units

*3 Branch lines support T-branch connections.
Item
Length of a trunk line or a sub-
trunk line (Maximum length when
two Repeater Units are used)
Length of a branch line
Total length of branch lines
Branching restriction
Number of connectable Units per
branch line *
Maximum length of a sub-branch
line
Total length of sub-branch lines
Number of connectable Slave
Units and Repeater Units
altogether per trunk line or sub-
trunk line
* This is the maximum number of Slave and Repeater Units that can be
connected to a branch line through the use of multidrop connections or T-
branch connections. The purpose of T-branching here is to have a sub-
branch line.
The types of node address that are set on a CompoNet network are given in
the following table.
Type of node address
Word IN Slave Unit
Word MIX Slave Unit
Word OUT Slave Unit
Bit IN Slave Unit
Bit MIX Slave Unit
Bit OUT Slave Unit
Repeater Unit
• For Word Mixed Slave Units, use the same node address type as for a
Word Input Slave Unit.
• For Bit Mixed Slave Units, use the same node address type as for a Bit
Input Slave Unit.
• If you connect a Word Input Expansion Unit (such as the XWT-ID16 or
XWT-ID08) to a Word Output Slave Unit, the result is treated as a Mixed
Slave Unit. Therefore, the node address type is a Word MIX Slave Unit
instead of a Word OUT Slave Unit.
