This is the 1553 device modelling API. It provides an interface to be used for implementing bus controllers and remote terminals.

The 1553 device interface is EXPERIMENTAL and UNSTABLE at the moment.

One limitation at the moment is that we do not support a specific bus monitor interface. However, it is possible to get reports via the "temu.mil1553send" event, this way you can sort of insert a virtual bus monitor. It does not let you configure a terminal as a bus monitor however. These events take an temu_Mil1553Msg pointer as the event info argument.

The bus is modelled on a two message approach: The first transaciton sends a command word, this allows the receiving RTs to take action on the first word. The second message is the actual data, this should be sent at the relevant time.

Normally, we distinguish the start and end message by the end message having a data pointer set and the begin message not having it set.

Controller to RT transfer:

  • Controller sends one message with a receive command and data
  • RT sends status word RT to controller transfer:
  • Controller sends transmitt command
  • RT sends status word and data. RT-to-RT:
  • Controller sends transmitt and receive command.
  • RT sends data in one message MODE-command without data
  • Controller sends mode command
  • RT sends status word MODE-command with data:
  • Controller sends mode command
  • RT sends status word and data word MODE-command with data word (receive):
  • Controller sends mode command and data word
  • RT sends status word Controller to RT broadcast:
  • Controller sends one messeage (no responses) RT to RT broadcast:
  • Controller sends receive and transmitt command
  • RT sends status and data (in broadcast) Mode command without data word broadcast:
  • Controller sends mode command (no responses) Mode command with data word receive
  • Controller sends mode command and data word (no response)
