I know this as I happen to have to work through this just yesterday. We used Chuck's solution of locking the block in remote (REMSW :Blockname.REMSW.1) and expanded on it by securing the remote setpoint value using a similar link back to itself with a value (RSP :Blockname.RSP.40.0).

I recall that in an earlier post it was suggested that a configured parameter can be linked to itself in the block configuration to lock its value. I've searched the archives but cannot find this post. Does anyone remember how to do this?
