The ioControl Move I/O Unit to Table command on a serial B3000 causes IVALs in debug mode to show corrupt values of 0 or 1.#QNAN.

The IVAL value is determined by the following pattern. If the XVAL for I/O point 0 is a valid positive value or –32768, then the IVAL for I/O point 15 will be 0. If the XVAL for I/O point 1 is a valid negative value, then the IVAL for I/O point 14 is 1.#QNAN. This pattern is repeated throughout the upper and lower positions on the rack.
