Hello, with the release RM21.03 we will provide PLC funtion blocks for AoE read and AoE write. IL_ECATAoeRead IL_ECATAoeWrite With these fuction blocks Aoe devices like an IO-Link Master can be accessed indirectly. So you can Read / Write Data from IO Link devices. IO -Link specific functionality has to be implemented within the plc program. Later on we will provide IO function blocks based on this two AoE function blocks for direct IO-Link access. If you have any questions feel free to ask.

regarding your questions, here are the answers.
1) Yes it is correct, actually we support only 64 devices. We plan to increase the number of supported in upcoming versions.
2) Today we don't support both and they are not scheduled. It is possible to add those featuers by software update. In case of redundancy an external device might be aditional necessary.
3) We haven't tested both devices yet, but basic EtherCAT communication should be possible. Regarding "Will we offer something similar", I will ask the experts and they will answer in a separate answer.
4) Yes, the ctrlX COREplus, will have an additional communication interfaces, e.g. for an EtherCAT slave. An aditional master port is basically possible but not scheduled.
