iChannelId: Channel ID of the FIFO channel.

bExecute: Edge-triggered signal for execution of the command.

tTimeout: ADS timeout (about 1 second).

bBusy: Becomes TRUE with a rising edge at bExecute, and remains TRUE until the block has executed the command.

bErr: Becomes TRUE if an error occurs while executing the command.

bErrId: Error number (ADS or NC error number).

iNoOfAxes: Number of axes for which the FIFO channel has been parameterised.

iNoOfFifoEntries: Number of FIFO entries for which the FIFO channel has been parameterised.
