mbus A429 Parametric Port Config.vi
Description
A429 Parametric Port Config function sets up the selected parametric port configuration. In addition to A429 Port Config function, voltage configuration is also available. This function opens a port and provides a portHandle. This portHandle must be wired to all subsequent VIs that uses this port.
| Parameters | ||
|---|---|---|
| error in | in | error conditions that occur before entering the function |
| sessionHandle | in | reference to the current Multibus session block handle |
| parametricPortNumber | in | parametric port index to configure |
| speed | in | selected port speed: Low or High |
| loopback | in | ARINC 429 words are looped back from Tx port to the Rx port |
| parity | in | selected port parity : Odd, Even, None. With parity set to None, port parity is not defined. Parity bit is transmitted with the value set by the application and no parity validity is checked upon receive |
| busLoad | in | number of ARINC 429 bus loads (all Rx units on the bus) |
| voltage | in | output peak to peak voltage in Volts |
| sessionHandle | out | reference to the Multibus session |
| portHandle | out | reference to the configured port |
| portNumber | out | configured port index |
| error out | out | error information |
| function return | out | function execution status |
Handle parameters are available as input and output. Output is a copy of the input and may be used to daisy chain successive VIs and reduce wire density.
Availability
Available in Multibus VI 1.0 and later.
