OK, I guess there are NO takers for the EA3-T4CL!
Does anyone have experience using a Controllino Maxi Automation with a Maple Systems HMI like the HMI5070B ???
Would I use a MODBUS TCP/IP protocol? Is the HMI the master or the PLC? Maple recommends the Controllino as the Master from their documents.
If that is the case then ==> 1.) Do I need to ASSIGN a static IP address tot he Controllino in code? 2.) Will the Controllino need a MAC address assigned?? 3.) If I do NOT intend to use a router (unless someone can tell me why I should) will I need a cross-over cable rather than a regular straight “patch” cable??
New to the HMI think with Controllino’s so I am asking for some good advice here.

Never mind Lukas I think I figured it out.
The DhcpAddressPrinter sketch requires that the Controllino have an physical ethernet cable connection to a router or a device that has a DHCP server that can SUPPLY an IP address to the Controllino and then you can see what address is assigned by the router to the Controllino in the Serial Monitor.
I hope this helps you w-mat in figuring out why the program was giving you that message.

Lukas,
I am ALSO having the identical problem that w-mets has described above ==> I run the DHCPAddressPrinter verbatim as you described in the Tutorial and I get the same replay w-mets did: “Ethernet shield was not found. Sorry can’t run without hardware.”
However, I did NOT uncomment ANY of the “Ethernet.init(?)” lines at all.
respectfully,

RedShift,
The best thing to do is to isolate the two voltage potentials. If they are different you do NOT want to have them tied together – isolation is best. I would suggest either use one of your RELAY outputs which are just allowing you to complete a circuit for your 28 VDC source or if you need to drive the 28 VDC source by one of the digital pins you can do so by using a simple MOSFET or BJT transistor to act as a digital “switch” (you can get these as an optically isolated version as well).
