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 (Slave Units and 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 (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). |
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

24 VDC ±10% |
Connection forms | Round cable II (4-wire) or Flat cable I 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 |
