MIL-STD-1553 Multiplex Data Bus Word Formats.

The emphasis in this chapter is the development of data word and message formats for MIL-STD-1553 data bus applications. This chapter is intended as a guide to the designer to identify standard data words and messages that are being used in todays avionic systems and subsystems. These standard words and messages, as well as the documentation format for interface control document ICD sheets, provide the basis for defining new 1553 systems. The standards defined in this chapter have met the test of application usage across several 1553 systems and thus provide the acceptable method for transmitting signals of this type in a 1553 system. Also provided in this chapter is the method for developing additional data word formats and messages that may be required by a particular system but are not covered by the standards provided herein. It is essential that any new word formats or message formats that are developed for a 1553 application follow the fundamental guidelines established in this chapter in order to ease future standardization of these words and messages if experience and usage demand it.
