What does this error mean?

[tlfritz]

We are trying to read and I2C device and since it is one that doesn't have sample code we are trying to run the vi directly so we can see what the result is. We aren't getting any change at all. We used the light bulb mode to see what was being blocked. It stopped at open and we kept tunneling until we found the source.

Every time we try to run the program it stops at the Read and this error occurs, what should we do to try and fix it?

Error Code: -63195
Source: Read/Write Control in FPGA_DIOWriteI2CConfig.vi

Thank you,
