The TCP/IP DAT is used for sending and receiving information over a TCP/IP connection between two remotely located computers. It captures all the messages without any queuing or buffering, and allows you to send it any messages you want.
This DAT can be used to intercept all the raw information being sent from a Pipe Out CHOP for example. The Pipe In CHOP and Pipe Out CHOP also communicate through a TCP/IP connection, though they use a specific syntax.
For Tscript. see send Command.
Parameters - Connect Page
mode - Specify if this operator is communicating as a client or a server.
address - If this node is communicating as a client, this should be the IP address of the server.
port - The network port to listen on or connect to, depending on of the node is the server or client respectively.
shared - Use the same connection as other networking DATs using the same network protocol.
format - determines how the incoming data is parsed into the table.
- One Per Byte - One row is added to the table per byte received.
- One Per Line - One row is added to the table per line received. The end of a line is delimited by \n, \r or a null character (\0).
Note: In this format messages will not be logged until one of those characters are received.
- One For All Received Data - One row is added to the table per message received. Since TCP/IP is a stream-based protocol, the end of a 'message' is arbitrary. It is simply the contents of the last read operation from the socket. If you are reading a custom message format, you'll likely need to build up a full message from multiple reads from the socket in Python.
active - This check box enables the connection.
Parameters - Received Data Page
/callbacks - The Callbacks DAT will execute once for each message received.
/executeloc - Determines the location the script is run from.
- Current Node
/current- The script is executed from the current node location.
- Callbacks DAT
/callbacks- The script is executed from the location of the DAT specified in the Script DAT parameter.
- Specified Component
/comp- The script is executed from the component specified in the Component parameter below.
/component - The component who's state change will trigger the DAT to execute its script when Execute from is set to On Panel Change. This component is also the path that the script will be executed from if the Execute from parameter is set to Specified Component.
/clamp - The DAT is limited to 100 messages by default but with Clamp Output, this can be set to anything including unlimited.
/maxlines - Limits the number of messages, older messages are removed from the list first.
/clear - Deletes all lines except the heading. To clear with a script command, here is an example:
opparm -c /serial1 clear
bytes - Outputs the raw bytes of the message in a separate column.
