    REF 54_ Feeder Terminal 1MRS750527-MUM Technical Reference Manual, General 5.1.13.10. LON inputs and outputs via a LON bus The REF 54_ feeder terminal offers up to 32 freely programmable LON inputs and outputs on the LON bus. The inputs and outputs use the LonMark Standard network variable (NV type 83 = SNVT_state) for sending and receiving process data.

  • Page 81: 12.Secured Object Control

    REF 54_ 1MRS750527-MUM Feeder Terminal Technical Reference Manual, General The basic operation principle is that every time the output value is changed by the configuration, the new value is propagated automatically over the LON network to all communication inputs that are bound to the output. The network variable connection can be from a single source to one or many sinks.
  • Page 82 REF 54_ Feeder Terminal 1MRS750527-MUM Technical Reference Manual, General In case of LON communication, the command time-out parameter has to be longer than or equal to 1.5 sec. A longer time-out is needed because the time for horizontal communication to take place needs to be taken into account. Normally the time-out parameter of the client must always be adjusted in accordance with the IED command time-out parameter (longer time-out on the client side).
