Response and Error
Codes
Each time the PLC performs a block write, it should then perform the
response code block read. This block read will return two bytes. The
first byte is the command number of the last block write performed.
The second byte will be the response or error code returned. If the error
code is a NACK (21) then the returned command number will be a 99.
