National Instruments 777517-01 Network Interface for FieldPoint

Part Number 777517-01 is the identifying part number for the National Instruments FP-1001 Network Interface for FieldPoint. This versatile module contains a rich set of features that make it an ideal choice for high-performance serial applications. First, it has a high-speed local bus that can rapidly communicate with I/O modules or respond to commands from the host. The network watchdog timer can detect failures in the host, cables, or the network connection and maintain a user-defined state on the channel. Likewise, the snapshot feature allows you to save the current configuration so that it can be loaded in the next power-up. Furthermore, with the Hot Plug and Play feature, I/O modules can be inserted or removed into the terminal bases without having to turn off the module. 

The 777517-01 supports full-duplex communication over RS-485 and is optically isolated to prevent fault coupling. It supports baud rates of 300, 1200, 2400, 9600, 19200, 38400, 57600, and 115200, and these are switch-settable. For communication, it uses 1 start bit, 8 data bits, 1 stop bit, and no parity while the integrity check occurs through the checksum method. The cabling distance between the host and the module is recommended to be 4000 ft (nominal). 

The 777517-01 requires a power supply range of 11 to 30 VDC. The module's power consumption is 1 W plus 1.15 times the total power consumed by the I/O modules. It works with FieldPoint Software, which contains various configuration utilities and driver software for seamless connection to application development environments like LabVIEW. Likewise, since the module uses Optomux protocol for communication, you can also use an Optomux-compatible server or send ASCII commands directly from the computer's serial port. 

The 777517-01 weighs 8.4 oz and is recommended for operation between the temperature range of –40° to +70° C while it can be stored between –55° to +90° C. The recommended relative humidity range for the module is 5% to 90% noncondensing. The device complies with electrical safety standards IEC 1010 and EMI emissions/immunity standard CISPR 11.
