The message tag specifies the actual message or set of bytes that the are sent or received from the hardware device. The ascii, bytes, nibbles, string, utf8, tokens, parameter, parameters, and filter subtags define the content of a message. The specific tags to use within the message tag depend on a combination of the hardware specification and the controls that the application needs. For example, if the hardware communicates with bytes or eight bits use the bytes tag. If the hardware understands four-bit increments, use a series of nibbles to define the message. You can also set a filter mask for a message. The contents of the filter determine which bits are relevant. The content of a binary message is often defined by using the bytes subtag to specify a special byte or set of bytes. The content of a American National Standard Code for Information Interchange (ASCII) message is normally defined by using the ascii subtag. You can set the delimiter with the tokens tag. Messages can also have parameters that hold important value information. Specify message parameters with the parameter and parameters tags. Defining the messages correctly is very important activity. WARNING: Defining the messages incorrectly and sending the wrong messages to a hardware device can be dangerous.
