1.6.6 Word Composing and Decomposing Block (Bits->Word & Word->Bits)
Sometimes it is necessary to put some bits together in order to transfer some information along the communica-
tion channel. The Word Composing Block, Bit->Word, is useful in this case to communicate, for example, with
the DGFC: it is possible to compose a word made of Drive ready, Drive ok, Ref is zero, Speed is zero, by
communicating on a single word.
The opposite operation is necessary when the digital words written, for example, by the DGFC have to be read.
The Word Decomposing Block, Word->Bit, allows to set some signals on a digital word; each signal composing
the word, on the Block input, can be combined with an output channel.
The Bits->Wordn Block has 16 inputs, where each of them can be connected to a signal; the output of the
Word compn Block contains the packed input bits.
The Wordn->Bits Block has an input word and 16 Bx Wn decomp output bits.
-
Wordn and Wn, where n is 0 or 1.
-
Bx, where x is a bit from 0 to 15.
Each function has two blocks: Word 0 and Word 1 – W0 decomp and W1 decomp.
