Ensure safe operation and maintenance of critical infrastructure.
The Control Lock System – Create Control Locks to prevent use and operation of selected equipment via the VTScada screens. Among other uses, locks are typically applied when technicians are physically working on dangerous equipment to prevent remote activation of that equipment.
Control Tokens – The Control Token system ensures that only one person (owner) at a time has control over a tag or set of tags. It is complimentary to the Control Locks system. A lock denies control and a token grants exclusive control (providing that the tag is not otherwise locked).
If a token is applied to a tag, only that token’s owner has control over the tag. A control token restricts user actions. It does not restrict automated actions. Any tag can have only one token. (This is in contrast to Control Locks where multiple locks can be placed on a tag for different reasons.)
