With the M-Series DAQ Cards, you would need to use a DAQmx Channel Property Node and specifically use the "Tristate" property. You can refer to the help on that specific property for more information on how to use it. Keep in mind that you would need to write first, then tristate the line so that you can read it. I have attached snapshot to illustrate this property node.
About I2C, you can refer to the this link for more information. Also you can use one of our USB product to simplify your development time as its designed specifically to interface with I2C or SPI.
