Transmitting 32-bit words:
If the same double-word connector is connected up to two successive connector
indices, this is transferred as a 32 bit word.
Examples:

1.
Only the high part of KK1000
and KK2000 is transmitted
as a 16-bit word.

- Each module can read out all circulating telegrams.
- Each telegram consists of 2 words = 2 x 16 bits.
- Each module can only write the telegrams of its own module address.
- In the above example, module 1 can write telegrams 1.0 and 1.1.
- The dispatcher (module address 0) provides the SYNC signal after the defined bus cycle time.
- The number of nodes is determined by establishing the bus cycle time and the number of channels per module.
- The dispatcher transmits as many telegrams with ascending node addresses and channel numbers as the
bus cycle time permits.
- If the total number of telegrams requires less time than the bus cycle time, the time up to the SYNC signal
is filled with NOP (No Operation) telegrams.
- The total number of telegrams (modules x channels) is limited to 1023, including pause and SYNC.
