Assets and Tags are two core elements in everyday process automation. The Tags represent an specific place in a plant where a measurement is needed. The Asset represents the specific device which gets used to fulfill the requirements at a tag.
Netilion distinguishes between the two by treating them as different data objects, but we enable an easy assigning of tags to assets and vice versa so that we can better keep track of the changes in your plant. See the below video for further details.
