Description

IbcTMO Changes the timeout period of the board.
Default determined by Measurement & Automation Explorer.

This option sets the timeout period of the board or device to v. The timeout period is used to select the maximum duration allowed for a synchronous I/O operation (for example, ibrd and ibwrt) or for an ibwait or ibnotify operation with TIMO in the wait mask. If the operation does not complete before the timeout period elapses, the operation is aborted and TIMO is returned in Ibsta. The timeout values listed below represent the minimum timeout period. The actual period could be longer.
