Interlocks

Each phase logic block may require interlocks. Interlocks provide safety and security for personnel and equipment by preventing the processing of a phase when other equipment or operators are not ready. You can assign all tags within the system as an interlock to a phase. There is no limit to the number of interlocks that you can assign to a phase. The physical interlocking is performed in the control system, not by the batch control system. In this case, the batch control system serves as a diagnostic tool by showing the status of interlocks.
