UDP In DAT
The UDP In DAT is used for receiving information over a UDP 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. Once this DAT has received a message it can reply to the sender using the 'send' command. Using the send command before it has received a message will not work because it doesn't know where to send data yet. When in multicast mode it doesn't send out a multicast message, it sends a reply directly to the originator for the last multicast message it got.
NOTE for Windows OS - If experiencing connection issues make sure Windows Firewall is disabled.
Parameters - Connect Page
protocol - ⊞ - Select which protocol to use, refer to the Network Protocols article for more information.
- Messaging (UDP)
- Multi-Cast Messaging (UDP)
address - The multi-cast IP address to listen for.
port - The network port to listen on.
shared - Use the same connection as other networking DATs using the same network protocol.
format - ⊞ - Determines how the incoming data is parsed.
- One Per Byte
perbyte- One row is added to the table per byte received.
- One Per Line
perline- 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).
- One Per Message
permessage- One row is added to the table per message received.
active - This check box enables the connection.
Parameters - Received Data Page
callbacks - The Callbacks DAT will execute once for each message coming in. See udpinDAT_Class for usage.
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 Callbacks DAT parameter.
- Specified Operator
op- The script is executed from the operator specified in the From Operator parameter below.
fromop - The operator whose state change will trigger the DAT to execute its script when Execute from is set to Specified Operator. This operator is also the path that the script will be executed from if the Execute from parameter is set to Specified Operator.
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 python script
bytes - Outputs the raw bytes of the message in a separate column.
Parameters - Common Page
language - ⊞ - Select how the DAT decides which script language to operate on.
input- The DAT uses the inputs script language.
node- The DAT uses it's own script language.
extension - ⊞ - Select the file extension this DAT should expose to external editors.
dat- various common file extensions.
- From Language
language- pick extension from DATs script language.
- Custom Extension
custom- Specify a custom extension.
customext - Specifiy the custom extension.
wordwrap - ⊞ - Enable Word Wrap for Node Display.
input- The DAT uses the inputs setting.
on- Turn on Word Wrap.
off- Turn off Word Wrap.
