National Instruments 780161-01 PXI PROFIBUS Master/Slave Interface

The National Instruments 780161-01 is a 1-port PXI PROFIBUS Master/Slave Interface designed for integrating PC-based controllers with PROFIBUS DP industrial networks. This interface supports both master and slave operations that allows flexible network configurations. The module is equipped with a NetSilicon NET+ARM processor operating at 33 MHz to ensure reliable network communication and control. In master mode, the 780161-01 interface manages network timing and data exchange that leverages the Configurator utility to set up the network efficiently. This utility works with device-specific .GS* files that enables precise configuration of I/O channels. The interface supports PROFIBUS DP protocols including DPV0 Master Class 1/2, DPV0 Slave, and DPV1 Master Class 2.

The interface transforms a PXI system into a powerful PROFIBUS device for slave functionality. It facilitates the integration of high-performance data acquisition, motion control, vision, and modular instruments into PROFIBUS-enabled systems. This capability is particularly useful for adding advanced measurement and control capabilities to existing industrial networks. The NI 780161-01 module features a reliable RS485 physical layer that supports baud rates from 9.6 kbits/s to 12,000 kbits/s. The onboard memory includes 2 MB of RAM and 1 MB of flash storage that provides sufficient space for storing PROFIBUS configurations and process data. The interface is designed to withstand industrial environments with an operating temperature range of 0 to 55°C. The module should be used under the maximum altitude of 2000 MSL and under the humidity range of 10% to 90%.

The 780161-01 interface comes with a LabVIEW driver that facilitates seamless integration with LabVIEW for developing HMI and SCADA applications. This driver allows users to write applications using intuitive tags while eliminating the need for low-level programming. The interface also includes diagnostic utilities for troubleshooting. The National Instruments 780161-01 PXI PROFIBUS Master/Slave Interface offers reliable communication, flexible configuration, and comprehensive software support for industrial automation applications. The unit is easy to install as its overall dimensions are 6 cm x10 cm (6.3 in. x 3.9 in.). The PROFIBUS isolation voltage is 500 VDC. Only company-specified products are allowed to be used with this NI 780161-01 module. For more details regarding installation and handling, consult the user manual.
