Note

You must land signals in module level parameters such as input, output, internal read and internal write parameters in order to deploy the signals in displays, history, trends, and control strategies.

Critical function block parameters are preserved during a partial EIOC download for any function block supported in the EIOC that is also in the Critical function block parameters preserved during partial download table (refer to the Downloading data topic).
