As seen in the previous lessons, within a SmartSockets application, interprocess communication occurs through messages. A message is a structured packet of information sent from one process to one or more other processes providing instructions or data. Messages can carry many different kinds of information in a SmartSockets application, including: alarms, variable-value pairs representing sensor information, and IPC information about a client.
These different kinds of messages are classified by message type. For example, numeric data is typically sent in a NUMERIC_DATA message, and an operator warning is typically sent in a WARNING message. A SmartSockets application can use both the standard message types provided with SmartSockets and user-defined message types you create.
