SNC Card for XNET
The SNC card is a USB-compliant network card providing the supervised RS-485 network connectivity to XNET. The SNC operates in both Style 4 (Class B) and Style 7 (Class X) modes, and can also be used for NRC-based ring networks.
Hardware Installation
The card comes pre-installed in new computers or you can install it in any available PCI or PCI Express slot following the Installation Instructions (A6V101018824 / A5Q00068394) provided with the hardware.
When Desigo CC connects to a NRC-based XNET network, the card requires an additional interface hardware to be installed in one of the network nodes. The interface requires a separate CC-2 or CC-5 card cage with NRC and NIC-C modules.
Configuration
The SNC is automatically assigned to a standard COM port by Windows when the drivers are installed. The installation process usually takes the next available COM port. There are no jumpers involved and no manual configuration is required.
Electrical Connections
The XNET connections are made on the terminal block on the front of the SNC card. Refer to Installation Instructions (A6V101018824 / A5Q00068394) for detailed wiring information.
Software Installation
The SNC card requires a device driver whose files are provided with the hardware. The installation procedure is described in the Installation Instructions (A6V101018824 / A5Q00068394).
