Fault/Status messages
Error messages which triggered the identification system
Error messages sent by the bus connection
<T>
: 1 bit, toggle bit
<TagType>
: 2 ASCII characters, for example: '02' for IPC02
<WordAddr>
: 2 bytes, word start address in the data carrier, range from 0000h to
FFFFh, depending on data carrier type.
<WordNum>
: 4 bits, number of words to be read or written, range from 0h to Fh,
depending on data carrier type.
The following applies for IPC03: The word count 0h is used with the
word address 0000h to read the preset data range on the data carrier
("Default Read").
The following applies for IQC33: The word count parameter must be
even-numbered because of the block size of 8 bytes. The word
address then indicates the offset in 8-byte increments.
<Year>
: 2 bytes ASCII, hexadecimal encoding, 00h ... 63h
