This function returns the status of the node.

Request Packet format [Node][11h][CRC(2 bytes)]

M550-V3, M560-V3, M570-V3, M80x, M81x, M84x
The returned packet consists of 10, four byte floating point numbers.(IEEE754)
1)   Identification code of the node.
2)   The amount of internal stack that hasn't been used.
3)   The number of parity errors detected by the node.(counts up to 255 then flips over to zero)
4)   The number of framing errors detected by the node.(counts up to 255 then flips over to zero)
5)   Firmware Revision Number
6)   EEPROM status 0 = OK, 101 or non zero = Corrupted
        (M550/M560/M570 only) 1 = eeprom repaired with block 1, 2 = repaired with block 2
