Chapter 2 System Configuration and General Specifications
2.1 System Configuration
A ROBONET system is comprised of one GateWayR unit and up to 16 axes of controller units. The GateWayR unit is
available in four types—DeviceNet specification, CC-Link specification, PROFIBUS specification, and RS485 SIO
specification—to support various field networks.
The controller unit may be a RPCON unit for 24-V pulse motor actuators or RACON unit for 24-V servo motor actuators.
When a simple absolute R unit is connected to the controller unit, the controller can be used as an absolute axis.
Also, the ROBONET extension unit can be used to implement a ROBONET system of multiple-row layout (multi-stage layout)
and connect non-ROBONET controller units (SCON, PCON-CF, ERC2) to a ROBONET system (via external SIO link).
A ROBONET system configuration is shown on the next page.
