4.15 Connecting the IO Device with DeviceNet
The DeviceNet unit (FCU6-EX871-40) must be mounted in the control unit's extension slot to connect
IO devices with DeviceNet.
Connect the dedicated DeviceNet cable to the DeviceNet unit's terminal block (enclosed).
When setting the parameters in the DeviceNet unit using the configuration software (parameter setting
tool), connect an RS-232C cross cable between the DeviceNet unit and personal computer (PC/AT
compatible unit). The configuration software must be installed in the personal computer at this time.
This unit functions as the DeviceNet master station. Refer to the DeviceNet Specifications (Release
2.0) issued by ODVA (Open DeviceNet Vendor Association) for details on the DeviceNet system.
