Connectable Master Units
CompoNet Master Units
Connectable Slave Units
CompoNet Slave Units
Maximum I/O capacity
Word Slave Units:1,024 inputs and 1,024 outputs (2,048 I/O points total)
Bit Slave Units:256 inputs and 256 outputs (512 I/O points total)
Maximum number of nodes
Word Slave Units:64 input nodes and 64 output nodes
Bit Slave Units:128 input nodes and 128 output nodes
Repeater Units:64 nodes
Bits allocated per node
address
Word Slave Units:16 bits
Bit Slave Units:2 bits
Maximum number of nodes
per trunk line or sub-trunk
line
32 nodes (including Repeater Units)
Applicable node addresses
Word Slave Units:IN0 to IN63 and OUT0 to OUT63
Bit Slave Units:IN0 to IN127 and OUT0 to OUT127
Repeater Units:0 to 63
Repeater Unit application
conditions
Up to 64 Repeater Units can be connected per network.When Repeater Units are connected in series
from the Master Unit,up to 2 extra segment layers can be created (i.e.,up to 2 Repeater Units are
allowed between a Slave Unit and the Master Unit).
Signal lines
Two lines:BDH (communications data high)and BDL (communications data low)
Power lines
Two lines:BS+and BS -(power for communications and internal Slave Unit circuits)
Power is supplied from the Master Unit or Repeater Units.
Communications power
supply
24 VDC ± 10%
Connection forms
Flat Cable at baud rate of 93.75 kbps:No restrictions
Other cables or baud rates:Trunk line and branch lines
Connections for Slave Units and Repeater Units:T-branch or multidrop connections
*1. FINS message communications are supported by CJ-series Controllers only.
*2. Drop-line connections are not supported with a baud rate of 4 Mbps, so Slaves with prewired cables (Bit Slaves)
cannot be used.
*3. Round cable, Flat Cable, and Flat Cable II are all different types of cable. To use more than one type of cable at a
time, Repeater Units must be used to separate them on trunk lines and sub-trunk lines.
