Hi György, Thanks for that info ... Highly appreciated :-)
I thought that there were problems when running it directly on a host with VMware, not in a vm ... Ok if that doesn't work, we should think of one or two pi PLCs which we hook up with Apache via VPN for integration tests. Do you have any experience with these pi PLCs?

I no longer work in the industrial automation domain, but I have joined the list to share the (little) knowledge I have in the area. As Chris correctly mentioned, EtherCat is the field bus protocol for the Beckhoff devices it uses a different physical layer and cabling than Ethernet. You probably don't want to implement this. The ADS protocol is used for the communication between different runtimes (soft PLCs, PLCs, HMIs). If you are looking for a way to test the ADS communication I suggest looking into TwinCat 3.1. It is the (latest) development environment for Beckhoff PLCs and it also contains a the soft PLC runtime. It used to have a free test/evaluation license which had some limitations (number of concurrent runtimes, maximum uptime) but it was sufficient for testing communication. On a last note, my experience was that these Beckhoff soft PLCs do not play well with virtualization at all. They completely break in a virtual environment.
