[foxboro] Lock Setpoint Value in Controller

Hello List Members,
I want to lock the value of the setpoint in a PIDA controller so that it
cannot be changed from the faceplate.  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?

Thanks in advance,
