3.6 Baud rate and node number
A serial network can be set up by connecting the transmit cable of the Master (PC, PLC) to the
receive cable of the first node, from where it is looped through to the receive cable of the second
node, and so on. The same procedure is followed with the receive cable of the Master, which is
looped through to all transmit cables of the drive node. This generation of Motion Controllers does
not require a multiplexer board for serial network operation. Multiplex mode is activated with a
new command:

In order to address the individual drives in the network, the node number must be specified before
each ASCII command to be sent (e.g. 3V100). Commands without a node number are adopted by all
drive nodes in the network (Broadcast).
