Could you please advise, is KUKA.Ethernet.KRL an option that is always available by default, or is it a paid option? In my used KRC4 Kss 8.3, I have Ethernet.KRL, but it seems that the client in the new KSS 8.6 does not have it. At least it's not in the additional software and it's not offered during the installation.
With this in mind, the following question arises: If I install the EtherCAT RS232 or RS485 extension, will it be possible to transmit data (not critical to speed) in this way?
