General instructions for addressing
The addresses "0" are reserved in the General Diagnostic Tools, for example, programming
devices.
The address "126" is conceived of as a delivery address (default value) for bus participants in
all rules; its address can be set via the field bus (SSA service).
The address "127" is reserved for addressing all bus participants or groups (broadcast) and
may thus not be set on an INVEOR.
The addresses of the master stations should start with the lowest addresses. This means that
a single master has the address "1" and additional masters then have the address "2", "3",
etc.
A maximum of 124 free slave stations thus remain in a PROFIBUS network with one master.
Repeater, coupler and FOC converter transmit their telegrams transparently from segment to
segment. They don't require their own address for this reason.
Both rotary switches (Switch 1/Switch 2) are set to the value "0" in the delivery state.
Only in this state can addressing via the parameter 6.060 "Fieldbus address" take place.
The default address 125 is active when the rotary switches (Switch 1/Switch 2) and the parameter
are set to address "0".
IMPORTANT INFORMATION
The address change only takes effect after "Power On".
