No, the picture you provided shows the remaining port you are referring to is the DH+ port. DH+ is a proprietary communication protocol (not standard rs232) You have two options, upgrade to a SLC 5/05 processor that has an ethernet port built-in, or purchase a bigger rack so you have an extra slot to put the ethernet module you purchase in.

No, my previous answer still stands. That converter is for the standard protocols only (Ethernet/RS232/RJ485), not the DH+ proprietary protocol. I believe the DH+ protocol, to be quicker, only has functionality in it to communicate with programming software (via very expensive PCMK-PCMCIA card) and between PLCs. I do not believe it has standard communication protocols in its data packets. So no matter how bad you want DH+ port to be your solution, it is just not within its capabilities. Upgrade processor or rack.

Thank you for your valuable informations. I have another idea, it is to connect the DH + with my hmi, so I could free the RS232 for ethernet. do you think this is achievable ?

No, as I said previously, twice!, the DH+ is a proprietary protocol. To communicate with the computer housing the HMI, you would need rs232 or ethernet.
There are exceptions to every rule. If your HMI is a Panelview (AB/Rockwell brand HMI) model that has a DH+ port, you could do that using pass-through settings. But I figure you would have done that already and not asked here if had that model of Panelview HMI) So short of that, the answer is still no. Tell your company, if they want it to happen, they need to do the recommended upgrades previously mentioned. If it is important enough to them, they are going to spend the few extra hundred and do it right.
