Note
The bus addresses on the Control Unit and on the PC must not be set the same.
5. A null modem cable must be used to connect the PC (COM interface) to the Control Unit.
This interface must not be switched.
1.5 Rules for wiring with DRIVE-CLiQ
The following rules apply for wiring components with DRIVE-CLiQ. The rules are subdivided
into DRIVE-CLiQ rules, which must be observed, and recommended rules, which, when
observed, do not require any subsequent changes to the topology created offline in
STARTER.
The maximum number of DRIVE-CLiQ components and the possible wiring form depend on
the following points:
● The binding DRIVE-CLiQ wiring rules
● The number and type of activated drives and functions on the Control Unit in question
● The computing power of the Control Unit in question
● The set processing and communication cycles
Below you will find the binding wiring rules and some other recommendations as well as a
few sample topologies for DRIVE-CLiQ wiring.
The components used in these examples can be removed, replaced with others or
supplemented. If components are replaced by another type or additional components are
added, the SIZER tool should be used to check the topology.
If the actual topology does not match the topology created offline by STARTER, the offline
topology must be changed accordingly before it is downloaded.
