Repeater Units for Greater Flexibility
Repeater Units can be used in a 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 subtrunk lines) from the trunk
line. Up to 64 Repeater Units can be connected per Master Unit and up to 32 Repeater Units can be
connected per segment layer.
Additional Information
Network power supply must be supplied to a sub-trunk line from the Repeater Unit.
Bit-level Distribution
Slave Units compatible with industry-standard e-CON connectors, clamping terminal blocks, or com-
pact connectors can be distributed 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 warehouses.
Bit Slave Units are available in two types: IP20 and IP54.
Five Communications Modes according to Number of Nodes, I/O
Points, and Allocated Memory
There are five communications modes that can be used according to the number of Slave Units, the
number of I/O points, and the location of allocated memory. Slave Units can be allocated in the Special
I/O Unit Relay Area or, if the CX-Integrator is used, in any part of the CIO, DM, WR, and HR areas.
This enables efficient use of memory according to the size of the system.
Data Exchange with Message Communications
Message communications can be used from the CX-Integrator running on a host computer or from the
CPU Unit of the PLC to access Slave Units and Repeater Units on a CompoNet network. This enables
easily to improve network and system maintenance.
