Signal Station

Introduction/Additional information: 

Introduction:

This message should be sent from a competent authority only, to inform about the status of different light signals at signal stations to all vessels in a certain area. The information should be displayed on an external display such as Inland ECDIS application as dynamic symbols. This message is an updated version of the “Light status message” (FI40) which cannot be updated due to the lack of a version indicator.

Additional Information:

  • This message should only been send by a competent authority from shore only. The message should be sent at regular intervals.
  • The ISRS code indicates the position of the signal and shall allow the match with the IECDIS display. It consists of UN country code, Fairway section number, Object code and fairway hectometre and is derived from the RIS Index as published in the ERDMS. The object code is used in a reduced way. The first two characters of the ISRS code for signal stations which are always “Si” are not transmitted. The type of traffic signal station and the number of signal station according to the RIS Index encoding guide are transmitted separately using the codification given in the table below. The IENC application has to recover the ISRS code and match it with the right ISRS code of the IENC, taking into consideration that the UN location code is missing.
  • The light status is coded from left to right from light signal 1 to 9
