# NI VeriStand

Read and write channels on a running VeriStand system

- Category: Test stands
- Capabilities: Operations
- Runs on: Windows x64

Work with a running NI VeriStand test stand. See what is deployed, and read or
write channels on the live system: faults, setpoints, model inports, alarms.

## What you get

- **Test connection** — shows the system state and which system definition is
  deployed.
- **Channel read/write** — by full channel path, such as
  `Aliases/EngineSpeed` or
  `Targets/Controller/Simulation Models/Models/Engine Demo/Outports/RPM`.
  Each write is read back, so a clamped or rejected write shows its real value.

## Setup

1. Install the connector from the **Connectors** tab on the Windows machine
   that runs the VeriStand Gateway. Or install it on another Windows machine
   with VeriStand installed.
2. Leave **VeriStand Gateway** as `localhost` when the connector runs on the
   VeriStand host. Otherwise set the gateway machine's hostname.
3. Run **Test connection** with your project deployed.

## Notes

- If VeriStand is not installed, the connector says so and points at the field
  to set for non-standard installs.
- A write acts on the running system, like typing into a workspace control.
  Take the same care.
