A 2-byte response code is returned with all responses. The first byte contains the
main code indicating the general category of the response, and the second byte
contains the sub-code giving more specific information. The table below shows
the main codes. Refer to 8-1 Troubleshooting for details on sub-codes.

01 Source node error
02 Destination node error
03 Controller error
04 Not executable
05 Routing error
10 Command format error
11 Parameter error
20 Read not possible
21 Write not possible
22 Not executable in current PC mode

The following table gives the addresses that can be used when reading or writing
PC data. The Data area address column gives the data area addresses normally
used in the PC program. The Address used in communications column are the
PC memory addresses used in CV-mode commands and responses. These
addresses are combined with the memory area codes to specify PC memory
locations. These addresses are not the same as the actual memory addresses
of the data.
The Bytes/item column specifies the smallest increment of data that can be read
or written for that area. The increment will be either words (2 bytes) or bytes (1
byte).
