But the encoder only supports Profibus, so my question is can I installed an IWlan/PB link and install all the components with Profibus interface. The crane operates with 80 meters from my access point. So can I install the IWlan/PB with a directional antenna that point to my access point?

I advice here to use a W78x Access Point together with the IWLAN/PB Link PN IO you have mentioned. It's possible to connect up to 8 PB Devices behind the IWLAN/PN Link PN IO. I think it's an indoor application I will recommend you to use 5 GHz which is allowed in Denmark. Keep in mind that the signalstrength is sufficient and that both antennas have a clear line of sight with a lot of room. If the antennas are in a small area it could be that there are so many reflections from it self that's disturbing the signal too much for PN IO traffic. It really depending on the PN IO update times you need or this could work wihtout the problems. Advice for an antenna would be the ANT795-6DN which can work in both 2,4 and 5 GHz. Recommended for this kind off aplications are normally RCoax solutions which is for material not much more expensive then what you use know. Maybe installating the equipment will be harder with RCoax. RCoax Manual

Please investigate first of all on site how the area is already used for Wireless issues. In some cases a site survey showed that the environment is used too much by other Wireless applications, just to prevent spending a lot of money on stuff you do not need than. Best regards J_Bell
