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 (i.e., per Master Unit). Up to 32 Repeater Units can be
connected per trunk line or per sub-trunk line. When Repeater Units are connected in series from the Master
Unit, up to two 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)
Standard or Sheathed Flat Cable at baud rate of 93.75 kbits/s: No restrictions
Other cables or baud rates: Trunk line and branch lines
Connections for Slave Units and Repeater Units: T-branch or multidrop connections
• Round cable I
• Round cable II
• Flat Cable I
• Flat Cable II
• Power is supplied from the Master Unit or Repeater Units.
than one type of cable at a time, Repeater Units must be used to separate them on trunk lines and sub-
trunk lines.
