摘要
An interlocked control system is provided for dual sided slot valves contained in a vacuum body between each of a plurality of adjacent process and transport modules. Separate valves are provided for each of two valve body slots, one body slot being separately closed or opened independently of the other. The separate valves allow a vacuum in the transport module while an adjacent process module is open to the atmosphere for servicing. Under control of the system, the valve may allow separate operation of the transport module and certain ones of the process modules, while a selected one of the process modules is in either a maintenance state or a locked out state for servicing. The system includes a separate controller for the transport module and a separate controllers for the process modules. A control interface coordinates the flow of signals between the controllers and local devices, and system user interfaces provide inputs to the control system from operational and service personnel.
