Many control system users are required to keep a written operator's logbook to provide traceability for their actions. VTS improves on this process by providing an electronic operator's notes display. Notes entered by users are automatically time-stamped and labeled with the operator's name. Once created, notes cannot be edited and the entire log is saved to an encrypted file, such that the file is unreadable outside VTS and cannot be edited with a text editor.
Operator notes are networked and therefore can be accessed and viewed by any VTS user with appropriate application security privileges. Thus, the feature acts as a VTS bulletin board, providing a method for users across the organization and across work shifts to communicate and record activities (i.e. Note: Please check engine number 1 on backshift. Overspeed during dayshift. Let me know. Thanks, Bob).
