The TCP/IP DAT is used for sending and receiving information over a TCP/IP connection between two remotely located computers. The Pipe In CHOP and Pipe Out CHOP also communicate through a TCP/IP connection, though they use a specific syntax. 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.
Parameters - Connect Page
/mode - Specify if this operator is communicating as a client or a server.
/address - You can put an IP address to listen on (22.214.171.124). This parameter is only needed for multicast protocols.
/port - The network port to listen on.
/format - Determines how the incoming data is parsed into the table.
- One Row Per Byte - One row is added to the table per byte received.
- One Row Per Line - One row is added to the table per line received.
- One Row Per Message - One row is added to the table per message received.
/script - This check box enables the connection.
Parameters - Log Page
/script - The Script DAT will execute once for each message coming in. The first argument ($arg1) is the message, the second argument ($arg2) is the line number (index starting at 0) in the DAT of the message.
/executeloc - Determines the location the script is run from.
- Current Node
/current- The script is executed from the current node location (for example, where 'cc' points to).
- Script DAT
/script- 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 whose state change will trigger the DAT to execute its script when Execute 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
/valcol - Outputs the raw decimal value of the message in a separate column. Use this when the incoming data is binary, and not readable ASCII.
