UDT In DAT
The UDT In DAT is used for receiving information over a UDT 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. UDT Streaming is a reliable, streaming, connection orientated protocol. A single server can send to multiple clients at the same time.
Handle received messages using the callback DAT attached to the UDT In DAT. Send replies using the udtinDAT_Class.
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.
- Fast Streaming
- Reliable Messaging
address - You can put an IP address to listen on (220.127.116.11). This parameter is only needed for multicast protocols.
port - The network port the listen on.
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
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.
- 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 udtinDAT_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.

Some operators have a DAT docked to them that contains some python functions. These functions, called "callbacks", get called when something in the operator changes.
