Telegram communication
Control and reply telegrams
The telegram communication in a master/slave
system is controlled by the master. A maximum
of 31 slaves (FC motors) can be connected to one
master, unless a repeater is used - see also the
description of the address format.
The master continuously sends control telegrams
addressed to the slaves and awaits reply
telegrams from these. The response time of
the slaves is maximum 50 ms.
Only a slave that has received a faultless telegram
addressed to that slave will respond by sending
back the telegram unchanged.
Broadcast
A master can send the same telegram at the same
time to all slaves connected to the bus. In such
broadcast
communication, the control telegram
broadcast
bit of the address bit has a value of 1 (see
VLT address). Address bits 0-4 are not used.
Contents of a byte
Each transmitted sign begins with a start bit.
Subsequently, 8 databits are transmitted. Each sign
is given via a parity bit set at "1" when there is an
even parity (i.e. an even number of binary 1
’
s in the 8
databits and parity bits together). The sign ends with a
stop bit and thus consists of a total of 11 bits.

Telegram build-up
Each telegram begins with a startbyte (STX) = 02 Hex,
followed by a byte that gives the telegram length (LGE)
