UDT Out DAT

Summary

The UDT Out DAT is used for sending information over a UDT connection between remotely located computers. Use the send Command to initiate the data output.

Although it is an 'Out' node, it can receive/reply messages from the machine(s) it sends to. The messages will appear in the DAT's contents (just like the UDT In DAT).

Parameters - Connect Page

Protocol /protocol - Selects the network protocol to use. Refer to the Network Protocols article for more information.

Port /port - The network port to send to.

Table Format /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.

Active /script - This check box enables the connection.

Parameters - Received Messages Page

Script DAT /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.

Execute From /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.

From Component /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 Output /clamp - The DAT is limited to 100 messages by default but with Clamp Output, this can be set to anything including unlimited.

Maximum Lines /maxlines - Limits the number of messages, older messages are removed from the list first.

Clear Output /clear - Deletes all lines except the heading. To clear with a script command, here is an example: opparm -c /serial1 clear

Value Column /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.
