Hello everyone,

I am new to the forum, and to programming with CodeSys.
I am dealing with IoT device for industry and I should check if a device is able to read/write global variables in an EtherNet/IP Master.

Since I do not have an EtherNet/IP PLC, I thought of using CodeSys as a softPLC.

I created a program with a set of global variables (GVL) and a task that increments them.

I would like to know if I need to enable any options so that the global variables can be read by IoT devices.
My device supports Class 2 Class (Explicit Messaging Connection) communication.

Thank you in advance for your help.
