Program Owner Protection
Assigning program ownership is done using the DH-485 WHO function via the
commands Set Owner and Clear Owner. The Set and Clear Owner commands
permit a terminal to “own” one or more processor files on the network. Ownership
means that as long as the owner is active on the network, other terminals cannot
access the online functions of the owned processor files.
When the owner becomes inactive (exits the network), another terminal can clear
the ownership of the inactive node and gain access to an owned processor file.
However, to do so, you must clear the ownership of the terminal. An owner can
clear ownership at any time.
Program ownership is lost when a pr ocessor cycles power or when
communication err ors occur .
