Communication
2.2 PROFINET communication
Transferring IP parameters
The IP parameters, consisting of IP address, subnet mask, and router can also be assigned
in various ways and transferred to the IO Device.
Possibilities for this are:
● The IO Controller assigns the IP parameters to the IO Device. In this case, the "Overwrite
IP parameters in device" parameter set with the SIMOCODE ES parameterization
software under "PROFINET Parameters → IP Parameters" must not be active.
Note
Deleting IP parameters
IP parameters assigned by the IO controller are stored non-retentively in the device,
i.e. they are deleted again when the supply voltage is switched off.
● The IP parameters are configured with SIMOCODE ES parameterization software and
transferred to the device. In this case, the "Overwrite IP parameters in device" parameter
under "PROFINET Parameters → IP Parameters" must be active.
Note
Transferring the device parameters
It is always possible to transfer the device parameters via the system interface.
If the PROFINET IO device name has already been configured in a different way, the
device parameters can be transferred via PROFINET, too.
Note
Assigning the IP parameters
The IP parameters can be assigned with the "SIMOCODE ES" parameterization software
in the Online & Diagnostic Functions. This function is not identical with the
parameterization of the IP parameters with the "PROFINET Parameters" dialog box.
Unlike in this dialog box, under "PROFINET Parameters → IP Parameters," the "Overwrite
IP parameters in device" parameter must not be active.
Note
Restarting the communication interface
Every change to the IP parameter with SIMOCODE ES in the "PROFINET Parameters"
dialog box requires a restart of the communication interface.
A new start of the communication interface interrupts all Ethernet and PROFINET links
and reestablishes them afterward.
