3152 DHCP status not reported in PLCNext or WBM and dhcp on lan3 failure
I found problem of handling DHCP configuration i can set DHCP on lan1 trough the online parameter setting (the only place to do it)
On WBM the dhcp is displayed but we don't have any information telling us we are in DHCP
On plcnext, no information we are in dhcp, displayed ip address is not the good one
On plcnext trying to setup dhcp on lan3 fail
It will be nice to allow setup dhcp in wbm and displaying ip in plcnext.
Regards
Alexandre

Hello Alexandre,
this is not possible because the networkadapters running the PNC or PND need static IPs.
We are working on a solution to enable multiple configurations per adapter in the future.
For now you will have to manually enable DHCP on these adapters.
Simmilar to this:
or disable PN via the WBM if you do not need it.
kind regards,
Oliver
Additionally:
We are continuously extending the WBMs functionality but this feature (changing IP Assing to dhcp etc.) is planned but sheduled for a later release so it will take some time until we have this in the WBM.
The PLCnext Engineer Settings are not downloaded to the PLC in any way and just describe the way for the Engineer/Project to connect to the PLC. This means the settings specified there will be used to connect to the PLC. It will not change the PLCs settings.
Already tried it to set manually dhcp on lan 3. Result is a crash of the plc runtime. (I think because i don't disable profibus service before).
I use the following working config.
LAN1 is dhcp to access (office network)
LAN2 is profinet (used to connected with plcnext engineer, i've tryied on other but can't detect the plc)
LAN3 on fixed ip
My question (just because i'm curious) , is why pn is on lan3 but plcnext interface say lan2 is the profinet interface.
Hello Alexandre,
if you manually set the adapter to DHCP, set an addional static IP on the same adapter that should stop the crash.
This way you have a DHCP IP for general usage and a static one for the PN part.
This is because X2 and X3 have PN - one is device the other controller.
