Distribution of data
  • At the beginning of each data transfer TransUC3 asks for the current network-status (reading the network-map).
  • TransUC3 tries to connect to the IP-Address or device-name of this UC3 which is defined as "Primary Host"
  • If this device doesn't answer within the time for the Connect-Timeout and TransUC3 knows the IP-Addresses of other devices of this network, it tries to make a connection to one of this UC3 devices (with UCTrsSet.exe there is a hint for this in a message box).
  • After receiving the current network-status TransUC3 sends the TransUC3 Request commands direct to each UC3 device by using a TCP/IP stack communication.
  • The Replies for this Request commands are sent from each UC3 direct to the TransUC3 PC.
  • TransUC3 gets in the Reply for each Request command exactly the same Reply command (if there have been problems).
  • If there are any problems there will be "Exception(s)" in the response File behind each Reply command.
  • So if there are no exceptions everything is o.k. and there have been no problems.
  • In the item "Error Handling" there are more detailed information about this.


  • We have also a converter for TransUC3 which makes it possible to send TransL2 ASCII-Files instead of XML-Files to UC3 devices. Because we get a reply for each command it's possible to build the response file like TransL2 would do this and so we are compatible to this kind of communication.
