Toggle bit
If you send two commands with the same SystemCode and same ParamTyp in succession on
the bus interface, you must change the toggle bit in the second command in order for the node
to detect the command.
<ByteNum>
: 4 bits, length of <IDCode>;
System IQ: 8 characters (08h)
<Channel>
: 3 bits, channel
Channel 1 (001b), channel 2 (010b),
channel 3 (011b), channel 4 (100b), all channels (111b)
<ConfAddr>
: 1 ASCII character, word starting address in configuration
range of tag. The following applies for IPC03:
01h = Protection Word
02h = Control Word
<Data>
: <WordNum> times 4 bytes. When communicating a word,
the highest value byte is transferred first and the lowest
value byte last.
<F>
: 1 bit, multiplex mode, 0 (0b): Mode off, 1 (1b): Mode on
<Fill Sign>
: 1 ASCII character
<FixLen>
: 4 bits, length of the read only code in bytes,
<FixType>
: 2 ASCII characters, for example: '02' for IPC02
<IDCode>
: 4 bytes, 6 bytes or 8 bytes (depending on the tag type)
<Identchannel>
: 3 bits, channel
1 (001b), 2 (010b), 3 (011b), 4 (100b), all channels (111b)
(but not <Sensorchannel> in trigger mode)
<P>
: 1 bit, password mode, 0 (0b): Mode off, 1 (1b): Mode on
<PSW>
: 4 bytes HEX, password
<ReplyCounter> : 1 byte, increases by 1 after each response and confirmation. The reply
counter starts from 0 after the system is switched on. When the maximum
value is reached, the counter skips the value 0 (from 255 to 1).
<Sensorchannel> : 3 bits, channel
3 (011b) or 4 (100b)
<Status>
: 1 byte (see chapter 10.1)
<T>
: 1 bit, toggle bit
<TagType>
: 2 ASCII characters, for example: '02' for IPC02
<TelegramLenH> : 1 byte, high byte or 16-bit telegram length = (N+1) div 256
<TelegramLenL> : 1 byte, low byte of 16-bit telegram length = (N+1) mod 256
<Triggermode>
: 8 bits
0 (00000000b): Trigger mode off
1 (00000001b): Trigger mode on
2 (00000010b): Trigger mode inverted
<WordAddr>
: 2 bytes, word start address in the tag, range from 0000h to FFFFh,
depending on tag type.
<WordNum>
: 4 bits, number of words to be read or written, range from 0h to Fh,
depending on tag 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 read/write tag ("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.
