4.2 Setting the Sercos address by means of rotary switches
About the Sercos address a logical addressing within the Sercos network of the nodes
is performed. This address has only local significance, i.e. it is unique within a Sercos
segment. The address is adjusted by means of the two HEX rotary switches, if the
switching position is ≠ 0x00. The setting is only applied at transition from NRT mode to
CP0. Changing the switches in other communication phases has no effect on the
device address. For the measuring system the addresses 1...255 can be used.
Setting the Sercos address via the service channel by means of IDN / S-0-1040
(switching position = 0x00), see chapter "Setting the Sercos address via the service
channel" on page 97.
Independent of the switching position, the current Sercos address is always shown in
IDN / S-0-1040.

4.3 Switching on the supply voltage
After the connection has been made, the supply voltage can be switched on.
The measuring system is initialized first of all and is then in NRT mode. In accordance
with the state machine for the communication phases CP0 to CP4 the measuring
system can be transferred by the master in the cyclical data exchange CP4.
After the initialization process is finished the following settings are performed:
