Unfortunately I don't know how to best start. I think the first question you need to answer is how you would like to access EtherCAT, as controller or as device. I assume it is the first. Then you can use different infrastructure in 4diac FORTE. I would say the better suiting for this would be our new Modular IO infra. For this you could have a look at a few modules that already do that: embrick, modbusng, wago modular. I hope this helps to get you a bit started.

Thx. That helped to clarify a doubt I have. Could not connect to device means that the port 61499 is not available or 4diac IDE could not establish a connection to your device. There are several reasons for this: the most simplest 4diac FORTE is not running. Could it be that your 4diac FORTE instance is crashing?
Other reasons is that a previous connection is not cleanly closed. Are you useing the latest development version from github? There where some change by Franz to improve connection management.

Unreliable connections are unfortunately a real problem that we currently have a hard time to fix. However we just merged yesterday the first commits that will allow to use OPC UA for the communication between 4diac IDE and 4diac FORTE. With that we hope that the situation will improve. Deployment will definitely be faster.
