We are using MII 12.2.4 to read values from Phoenix Contact PLCs. We have a Phoenix OPC server running on our PCo box that PCo talks to. We are using version 2.1.6.1 of PCo.
We are getting errors in the PCo log that are related to tags that we are not intentionally reading. They are in the same tag group that we are reading from but we are not specifying the particular tags that are showing up with errors in the log.
My question is this, when a tag query is executed in an MII transaction, does it retrieve the entire tag group first and then get the particular tags that are specified in the query?
Thank you,
Mike
