2017.1 - Expose devices
In large projects with multiple Cores it is required to network them together and have one Core operating as a master. Examples would be floors in a hotel or an office tower where it may be suitable to have a standalone Core on each floor in order to have a certain level of decentralization.
Expose devices feature makes IO modules or virtual devices of one Core discoverable on backbone Modbus network. When looking at device list of the master Core, it looks like as if all these devices where connected or running directly on the master Core.
