Description
The National Instruments PXIe-8431/8 PXI Serial Interface Module, with Part Number 781473-01, supports communication standards RS485/RS422 and features 8 ports for full duplex transmission. It is designed to operate in a configuration with one Master and multiple Slaves, specifically supporting up to 5 controllers and up to 10 receivers per controller under RS-422. Furthermore, this module provides Modbus support over RS-485, RS-422, and TCP/IP network (Modbus TCP), allowing for a network configuration of one master and up to 247 slaves. There are two transmission modes in Modbus that ensure compatibility across connections with slaves.
