Definitions
Inputs and outputs can be locked or protected. The person who issues a lock or protect is called
the owner.
When an input or an output is locked, no one at all may change its state. That is, no one may use
it in a route and no one may “protect” it. No one may release the lock except the owner.
When an input or an output is protected, no one except the owner may change its state. That is,
no one except the owner may use it in a route and no one may “lock” it. No one may release the
lock except the owner.
To release a lock is to free the input or output to be used in any way and by anyone.
A force release is an override of a lock or protect without regard to ownership. Some control
panels can be configured to allow forced release.
