CompoBus/S System Configuration
Section 1-2
• Uses the Slave registration function to monitor which Slaves are joined to
the network.
• Communications can be stopped when a communications error occurs.
CQM1 Master Units
• Only one Master can be connected to a single PLC.
• Up to 32, 64, or 128 I/O points (DIP switch used to switch setting).
• Alarm output terminal provided to detect errors.
SRM1 and CPM2C-S Master Units with Built-in CPU Units
• Compact CPU Unit with built-in CompoBus/S communications functions.
• Up to 256 I/O points for CompoBus/S functions.
• Communications status stored in CPU Unit's AR Area.
Slave Characteristics
Remote Terminals
• Input or Output Terminals for general-purpose use.
• 4-point, 8-point, and 16-point Transistor Remote Terminals.
• Remote Terminals with no-contact transistor I/O, connector transistor out-
puts, or relay contact outputs.
Remote Terminals (3-tier Terminal Blocks)
• Input or Output Terminals for general-purpose use.
• 16 points: 8 inputs and 8 outputs mixed.
• Wiring is simple because common terminals for I/O wiring are located at
each point on the 3-tier terminal block.
Connector Terminals
• All I/O wiring can be done using connectors, reducing the amount of labor
for wiring.
• Mounting brackets allow the direction of mounting to be changed.
Water-resistant Terminals
• Input or output terminals of IP67 construction.
• 4 or 8 inputs or outputs.
• Connecting to communications cable, I/O power supply, and I/O through
shielded connectors.
Remote I/O Modules
• Modular type that allows PCB mounting.
• 16-input model and 16-output model.
• User’s devices can be customized as CompoBus/S Slaves.
Sensor Terminals
• Easily connects to Photoelectric Sensor or Proximity Sensor with XS8
Connectors.
• 8-input/8-output model and 4-input/4-output model.
• Remote teaching and external diagnosis are possible by using output sig-
nals of the Sensor Terminal.
Fiber Amplifier Communications Units
• Reduced wiring with ON/OFF output and power supply wiring not
required.
• Connecting a Fiber Amplifier Unit allows connection of up to 14 Optical
Fiber Sensors.
