Description

This command is the string that the DataHub sends to all clients when a point value changes (i.e. a point exception occurs). The DataHub also listens for a point command because this is the mechanism that it uses to get updates from another DataHub that it is tunnelling. This is not a command that a user would normally emit. Point changes should be sent to the DataHub using the write or cwrite commands.
