vtex10xxA_set_communication_timeout
Function Prototype
VISTATUS _VI_FUNC
VTEX10XXA_SET_COMMUNICATION_TIMEOUT (VISESSION VI,
VIINT32 TIMEOUT);
Function Parameters
vi = contains a session handle to the instrument. This handle is
obtained by the function and remains valid until the session is
closed.
SETS THE TIMEOUT VALUE (IN MILLISECONDS).
INDICATING HOW LONG TO WAIT FOR INSTRUMENT
TO RESPOND. IN HIGHER LATENCY NETWORK, IT IS
BETTER NOT TO REDUCE DEFAULT TIMEOUT VALUE.
VALID RETURN VALUES: 1000 THROUGH (231-1).
DEFAULT VALUE: 25000 (25 SECONDS).
DATA ITEM RESET VALUE
Reset will not change value of this parameter.
Description
This function sets the timeout value when a LAN communication
error occurs. It is recommended for advanced users only.
Example
//sets the LAN communication timeout to 10 seconds, if a LAN
communication error occurs
vtex10xxA_set_communication_timeout(vi, 10000);
