Internal Software Error occurred in CPP_API software

[HoNeu]

Hello!

We develop an engine test software in C#/.Net and use Daqmx 9.61 and a compact daq chassis 9188 to acquire some analog input data.

Our customer gave us the response that sometimes the application throws following exception:

Internal Software Error occurred in CPP_API software. Please contact National Instruments Support.

Requested Code: -225581

Task Name: DataAquisitionSlaveAiTask

Status Code: -224803

Only a restart of the chassis and a restart of our software helps to get this back working and stops the production of our customer.

This error occurs sometimes twice a week, sometimes every 2 or 3 months and the application and measurement is running around the clock without any problems.

Do you have any information what the meaning of this codes is and what we can check to eliminate this error?

Regards

Holger

hello,

one point you can check is your power supply (12V or 24V).

the specification says: Voltage input range is: 9 to 30 V

but there was the same problem with a 24V power supply.

second point you can check is:

please download the following example from our website.

This example program shows you how to continuously acquire data (a waveform) using an internal clock and a digital start and reference trigger. 

Please use it as a reference. (http://digital.ni.com/manuals.nsf/websearch/689DBD583FF007D7862578D800734C52)
