Why Metrology Cloud?

❖ Increase process efficiency

by digitization

❖ Remove format/schema

differences by standardization

❖ Automate process stepping

and triggering using Smart

Contracts

❖ Focus on specific processes

Demo of the MC Digital Representation

Requirements for a unique

identifier:

❖ Create centralized

registry for

manufacturers

❖ Manufacturers use

unique DeviceID

❖ Integration of existing ID-

Systems by prefixing

when ever applicable.

❖ Way of securely

communicating

Measuring Instrument ID

(MIID) between Devices

or Devices and the

Metrology Cloud

From Identificator to

Authentificator

❖ Only data

copied to the

node will be

shared

❖ The digital CV

stores all

(historical)

data of an MI

❖ Digitize the mediums used, processing and all triggers for maximum efficiency.

❖ Current state of the demo of the Single Point

of Contact

❖ Goal after 3 years: working PoC prototype

Currently Demoable Features:

❖ 4 user types

❖ Adding new SW Version

❖ Starting SW-Update process
