Hello Patcha30

yes this works, you can also use the same hmi proect or HMI Tags in multiple HMIs but you have to be careful if more HMis write to the same datapoints. In this case you cannot define who is writing first, so if this is not important then everything will work, but if you have datapoints that should be writte only from specific HMIs then you have to use different DBs or tags in your PLC/HMI
