Example 5: Access error
When failing to read/write parameters by using PKW, an error message will be shown from
the CME-PD01. Suppose that the data sequence master sent is 202D 8000 0000 0002. If
this address (0x07FD) cannot be found by the VFD-E, it will respond the data sequence
702D 8000 0000 0000, request ID is 7 which means cannot process request (with error
number), and error number is 0 (Illegal Parameter Number).
