The following media can be used.
• Round cable I
• Round cable II
• Flat Cable I
• Flat Cable II
Note Round cable I, round cable II, Flat Cable I, and Flat Cable II are all different
Refer to 1-2-1 Cable Types, Baud Rates, and Maximum Distances in the Master Unit
Operation Manual.
CompoNet Master Units
CompoNet Slave Units
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)
Word Slave Units: 64 input nodes and 64 output nodes
Bit Slave Units: 128 input nodes and 128 output nodes
Repeater Units: 64 nodes
Word Slave Units: 16 bits
Bit Slave Units: 2 bits
32 nodes (including Repeater Units)
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
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).
Two lines: BDH (communications data high) and BDL (communications data low)
Two lines: BS+ and BS− (power for communications and internal Slave Unit circuits)
• Power is supplied from the Master Unit or Repeater Units.
Round cable II or Flat Cable I/II 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
This section gives the specifications that are the same for all Slave Units. For
specifications that vary with the Slave Unit, refer to the section for each Slave
Unit.
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.
