7.3 Setting the rotary encoding
switches
With the other rotary encoding switches (x10 / x1), you set the last two digits
of the IP address when you are using EtherNet/IP or Modbus TCP.

Table 10: Assignment of the rotary encoding switches for each protocol
The setting you make to select a protocol is described detailed in the protocol-
specific sections.
In delivery state no protocol settings are stored in the device. In this case
only the desired protocol has to be chosen. To take over a changed rotary
encoding switch setting (protocol setting), a power cycle or “Reset” from the
Web interface is necessary.
Once you have set the protocol using the rotary encoding switches, the
device stores this setting when it starts in cyclic communication. Changing
the protocol using the rotary encoding switch is no longer possible after this
point. The device will always start using the stored protocol from that point
on. The IP address can be changed depending on the selected protocol.
To change the protocol, carry out a factory reset. In this way you restore the
factory settings of the respective device. How you perform the factory reset
for your device is described in chapter
on page 38.
If you position the rotary encoding switch in a manner that is invalid, the device
signals this to you with a blink code (the BF/MS LED blinks in red three times).
