Network configuration

PROFINET IO and DCP
DCP can only be used in the PROFINET IO mode. When the
module is initialized, the IP address is transferred to the
PROFINET IO communication stack. If there is a need to change
the IP address it should be done with a DCP tool (like Siemens
Step7). If some of the other methods is used to change the IP
address, the module must be restarted to enable any changes.
Duplicate IP address detection
RETA-02 has a duplicate IP address detection mechanism when
using Modbus/TCP. If the module detects another device on the
network, which has the same IP address, it lids the Network status
led in red and starts to blink the Module status led in red.
In PROFINET IO network the controller has the duplicate IP
address detection mechanism.
