PVStatus SINT Status
Primary variable status:
0x00 : variable is not connected.
0xc0 (decimal -64): variable is connected.
SVStatus SINT Status Second variable status. Values as for Primary.

CommandStatus SINT Status
Command error summary. If bit 7 is 1 then the remaining bit
indicate communications errors as follows:
Bit 6: vertical parity error.
Bit 5: overrun error.
Bit 4: framing error.
Bit 3: longitudinal parity error.
Bit 2: reserved, set to 0.
Bit 1: buffer overflow.
Bit 0: not used.
If bit 7 is 0 the remaining bits contain a command specific
response code in the range 0 to 127. Some common
response codes are:
0: Success – command completed successfully.
32: Busy – the device is performing a function that cannot
