The method described here is how to connect via the USB port of an NE0A-series or NE1A-series Controller. Note (1) The OMRON NE0A USB Port Driver must be installed to connect the Network Configurator online using the USB port for the NE0A-series Controller. For information on the driver installation procedures, refer to Appendix C Installing the NE0A USB Port Driver. (2) For details on other methods of connecting online, refer to the DeviceNet Safety System Configuration Manual (Cat. Z905). Basic Flow of Operations The basic flow of operations for downloading as follows: 1, 2, 3. . . Connecting online (connecting the Network Configurator and NE0A-series Controller) 2. In addition to the above, this section also describes the following online operations. Uploading from Devices Reading the configuration from a device. Resetting Devices Restarting a device and deleting a set configuration to return to the default settings. Setting Device Passwords Setting device passwords to prevent unauthorized access to devices (for changing configurations, changing modes, etc. ).

Connecting online in this way enables shorter download and upload times to the overall network than through the NE0A-series Controller. Connecting to the NE0A-series USB Port In addition to the Network Configurator and the USB connection for the NE0Aseries Controller, NE0A-series Controllers can be connected online to DeviceNet at a specified baud rate. The baud rate is set using automatic baud rate detection at the time when the NE0A-series Controller is turned ON. Therefore, when communications frames are not being sent over the network, the Controller will remain offline. This function can be used effectively in these cases.

[. . . ] A function executed by a safety-related system to achieve a safe state for a machine hazard. A unique number set for a safety network. With CIP Safety, a system can be built that included multiple networks. In this type of configuration, devices are uniquely identified and mutually confirmed using a TUNID that combines the network number and node address. [. . . ]
