Sigmatek ETV1021-L VARAN Terminal
The Sigmatek 12-230-1021-L Elnbauterminal VARAN ETV1021-L is a built in operator terminal for industrial automation. It is identified by the ETV1021-L model reference and the 12-230-1021-L part number. The terminal provides a graphical user interface for machine operation and monitoring. It communicates with the DIAS system through VARAN. The unit is used in packaging machines, printing presses, injection molding machines and special purpose equipment.
Operator Terminal Function
The ETV1021-L displays machine status, parameters and fault messages. Operators can enter commands, change setpoints and acknowledge alarms. The terminal may include a touch screen or function keys depending on configuration. It communicates with the CPU module through VARAN for real time data exchange. The interface helps improve usability and reduce training time.
VARAN Communication
VARAN is a real time Ethernet protocol developed by Sigmatek. It provides fast and deterministic communication between the terminal and the control system. VARAN allows short cycle times for responsive operation. The interface supports daisy chain topology and reduces wiring complexity. It also enables diagnostics and parameter setting from the control system.
Visualization and Programming
The terminal is programmed using the LASAL visualization tool. LASAL allows creation of custom screens, animations and data links. Users can design interfaces that match the machine requirements. The software supports multiple languages, user levels and password protection. This helps secure critical parameters and prevent unauthorized changes.
Applications
The ETV1021-L is used in many industrial machines. Typical applications include packaging lines, printing presses, injection molding machines, textile equipment, woodworking machines and assembly stations. It is also used in handling systems, robotics and test benches.
Installation Notes
Installation should follow the manufacturer instructions. The terminal is usually mounted in a panel cutout. Mounting clamps should be tightened evenly to ensure a proper seal. Power and communication cables should be connected according to the wiring diagram. Cable routing should avoid sources of electrical noise. After installation, the system should be tested for correct display and touch response.
Maintenance
Regular maintenance includes cleaning the screen with a soft, damp cloth. Abrasive cleaners should be avoided. The front panel should be checked for scratches or damage. Touch response should be tested periodically. The unit should be kept away from excessive heat, moisture and dust. Following these practices helps ensure long service life.
Conclusion
The Sigmatek ETV1021-L VARAN Terminal is a reliable operator interface for DIAS automation. It combines clear visualization, VARAN communication and flexible programming. Correct installation and maintenance help ensure dependable performance.
