Note: If the master requests one parameter value, the value of PKW3 and PKW4 will not be valid.
Task requests and responses: When passing data to slave machine, master machine use request
label while slave machine use response label to positive or negative confirmation. Table 5.5 and Table
5.6 list the request/response functional.
