CompoNet Network Specifications
Section E-1
*3 Branch lines support T-branch connections.
In Data Rate of 93.75
kbps
* 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.
E-1-4 Types of CompoNet Network Addresses
The types of node address that are set on a CompoNet network are given in
the following table.
IN Slave Unit Node
Addresses Are Used
for Mixed Slave Units
• 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.
