Owning Palette: NI-SWITCH VIs

Use the NI-SWITCH utility VIs to exercise additional features of an NI switch.

Palette Object Description
niSwitch Initialize With Options VI

Returns a session handle used to identify the switch module in all subsequent NI-SWITCH calls and optionally sets the initial state of the session.

niSwitch Initialize VI

Returns a session handle used to identify the switch module in all subsequent NI-SWITCH calls.

niSwitch Reset VI

Disconnects all created paths and returns the switch module to the state at initialization. Configuration channel and source channel settings remain unchanged.

niSwitch Get Relay Name VI

Returns the relay name that is in the relay list at the specified index.

niSwitch Get Channel Name VI

Returns the channel string that is in the channel table at the specified index.

niSwitch Convert Thermocouple Reading VI

Converts a voltage reading from a thermocouple into a temperature value.

niSwitch Convert Thermistor Reading VI

Converts a thermistor voltage into temperature.

niSwitch Temperature to Volts VI

Converts a temperature to a thermocouple voltage.

National Instruments has chosen thermocouple polynomial expressions that are valid only for particular temperature ranges (given in the VI diagram). These polynomials come from the NIST Monograph 175.

If you wish to use a different conversion formula, you can edit this VI and enter your own equation into the appropriate formula node.

niSwitch Volts to Temperature VI
