When using niDCPower_WaitForEventWithChannels with a timeout of more than 60 minutes, the function can time out earlier than expected

If you use a timeout value greater than 60 minutes for niDCPower_WaitForEventWithChannels or niDCPower_WaitForEvent, it can time out sooner than expected.

For example, if you set a timeout of 86,400 seconds (24 hours), it might return with an error after about 500 seconds.

The timeout value of "-1" was previously allowed but the behavior was undefined.

Workaround:

Use a smaller timeout value. Values 3600 seconds (1 hour) or less should return correctly. If you need to wait longer, loop on niDCPower_WaitForEventWithChannels while using a smaller timeout value, clearing the timeout value after all but the last call.

Hardware errors (e.g. overload protection) on some NI-DCPower instruments can hang the session until the device is reset

A race condition can occur if an NI-DCPower instrument is in the middle of a function call when a hardware error occurs. In this situation, the function will not return until the instrument is reset.

One way to identify a hardware error is if the instrument's front panel LED is red.

Affected instrument models: PXIe-4132, PXIe-4145, PXIe-4136, PXIe-4137, PXIe-4138, PXIe-4139, PXIe-4140, PXIe-4141, PXIe-4142, PXIe-4143, PXIe-4144, PXIe-4145.

Workaround:

If this hang occurs, perform a device reset using the System Configuration API or from MAX.
