Addressing
If several frequency inverters are connected to a system bus, these devices must be assigned with unique
addresses. This is preferably implemented via DIP switch S2 of the frequency inverter (Section 5.2.2.2).

FI 4 OFF OFF 38
For field bus modules, no assignment of addresses is necessary. The module identifies all the frequency
inverters automatically. Access to the individual frequency inverter is made via the field bus master (SPS).
Details of how this is carried out are explained in the relevant bus instructions.
I/O extensions must be assigned to the relevant frequency inverter. This is carried out by means of a DIP
switch on the I/O module. A special case for the I/O extensions is the "Broadcast" mode. In this mode, the
data of the I/O extension (analog values, inputs etc.) are sent to all inverters simultaneously. Via the
parameterisation in each individual frequency inverter, a decision is made as to which of the received values
are to be used.
NOTE
Care must be taken that each address is only assigned once. In a CAN-based network double
assignment of addresses may lead to misinterpretation of the data and therefore undefined
activities in the system.
Integration of devices from other manufacturers
In principle, the integration of other devices into this bus system is possible. These must support the
CANopen protocol and a 250kBaud baud rate. The address range (Node ID) 1 to 4 is reserved for additional
CANopen masters. All other participants must be assigned addresses between 50 and 79.
