1-1-2 Gateway Unit Features
A Gateway Unit can be used to take advantage of CompoNet features to simplify wiring.
A Selection of Communications Cables
The following communications cables can be used with CompoNet systems: Round Cable I
(2-conductor), Round Cable II (4-conductor), Flat Cable I (standard), and Flat Cable II (sheathed).
Note: Refer to the CompoNet Slave Unit and Repeater Unit Operation Manual (Cat. No. W457) for details on
cable types.
Multinode Connections
CompoNet systems can be used for multinode, high-density remote I/O communications.
Maximum I/O capacity:
Maximum nodes:
Up to 6,144 CompoNet Slave Units can be connected to a CC-Link Master Unit. (Communications
mode 4 must be set.)
Bit-level Distribution
CompoNet Slave Units with industry-standard e-CON connectors, clamping terminal blocks, or small
connectors can be used to distribute I/O at the bit level. This enables distributed control in distributed
devices, such as sensors and other devices located over a wide area on conveyors or in ware-
houses.
Easy Installation and Setup
CompoNet systems can be easily installed and set up.
• Seven-segment Display
The number of connected CompoNet Slave Units is shown on the seven-segment display.
This enables easily checking system operation.
• Participation Flags and Communications Error Flags
The network participation status of CompoNet Slave Units can be checked at the PLC.
When a CompoNet Slave Unit joins the network, a Participation Flag that corresponds to the node
address of the Unit turns ON. If a CompoNet Slave Unit that was participating in the network is
disconnected from the network, a Communications Error Flag that corresponds to the node
address of the Unit turns ON. (Communications mode 0 to 3 must be set.)
• Automatic Baud Rate Detection
The CompoNet Slave Units will automatically detect and use the baud rate that is set in the Gate-
way Unit. Setting the baud rate is not necessary for any of the CompoNet Slave Units.
Repeater Units for Greater Flexibility
Repeater Units can be used in a CompoNet network to enable the following network expansions.
• Extending the cable length
• Increasing the number of nodes
• Branching from the trunk line
• Changing the type of cable
Repeater Units can be used to extend up to two segment layers (called sub-trunk lines) from the
trunk line. Up to 64 Repeater Units can be connected per Gateway Unit and up to 32 Repeater Units
can be connected per segment.
Note: Supply communications power to a sub-trunk line from the Repeater Unit.
Refer to the CompoNet Slave Unit and Repeater Unit Operation Manual (Cat. No. W457) for detailed wir-
ing methods.
