NI SLSC stands for NI Switch Load and Signal Conditioning. It is a hardware system that extends the PXI or CompactRIO platform with the ability to add custom front-end modules.

In this tutorial, it will help to guide you on how to use SLSC Extension of a Real-Time Controller with VeriStand.

Hardware Setup

List of hardware use:

  • Host PC 
  • PXI Linux RT Controller
  • SLSC chassis with few modules
    • NI SLSC-12001
    • NI SLSC-12201
    • NI SLSC-12252

Network Settings:

All hardware will use a Static IP Address. Manually change their network interface settings and make sure that they are in the same subnet
  1. Host PC: IPv4 Address field set to 192.0.2.3 and Subnet Mask set to 255.255.255.0
