IZOVAC offers its Customers engineering services to transfer manual and semi-automatic operation of vacuum equipment to fully automated operation based on WAGO microcontroller technology and software designed by IZOVAC.

Automated vacuum equipment control system is based on microcontroller and is designed to ensure man-free operation of pumping system, vacuum valves, locks and transferring of all system data to the main computer (if required). The key advantages of our solution are flexibility, reliability, and adaptability.

Microcontroller systems comprises three main sub-units:

1) Master network controller.
Master network controller ensures fulfillment of the following objectives:

• Cyclical data exchange between input-output modules
• Execution of pumping equipment operation algorithm
• Communication support with equipment computer through industrial network MODBUS

2) Exchangeable input-output modules (I/O modules) ensure connection of sensors and execution units, and include galvanic decoupling circuits and channel status indicators.
Modules are classified as following:

• Digital input module connect any 24V and 220V digital field devices, and dry contact sensors.
• Digital output module connect 24V or 220V execution units.
• Analogue input module receives signals from analogue sensors with standardized values of 0-10 V.

3) Service modules.

• End module completes the internal data circuit and ensures correct data flow. End module is placed onto the whole assembly once all bus couplers and I/O modules are connected.

4) Power supply modules. The supply modules provide field side power to several I/O modules, located immediately after supply module.

Proposed system can operate in three different modes:

1. Manual mode checks wiring, sensor and executed units’ connection and adjustment procedures.
2. Automatic mode is designed to automate execution of all pumping procedures and ensures the presence of pre-set vacuum condition during deposition processes.
3. Semi-automatic (step-by-step) mode is also designed to safely execute necessary maintenance and servicing procedures. During this mode of operation special part of software prevents unpremeditated activation of executing units (sputtering sources, power supply units, etc.).  An operator can manually control the pumping process, and also move carriage during servicing.
