​​Modernization & Retrofit 

Existing facilities often contain useful equipment that does not need to be replaced. 

CrystalVision can upgrade or expand existing control systems while retaining suitable infrastructure. 

Typical retrofit projects may include: 

  • Adding new sensors or equipment 

  • Updating PLC software 

  • Expanding I/O 

  • Adding HMI or SCADA 

  • Connecting previously separate systems 

  • Improving alarm management 

  • Adding historical data and remote monitoring 

  • Upgrading communication between devices 

This allows facilities to improve automation and visibility without replacing the entire control system. 

​

​​​

SCADA, Alarms & Data 

Control systems can be integrated with Crystal OPC, CrystalVision’s SCADA and HMI platform. 

Depending on the application, this can provide: 

  • Real-time graphical monitoring 

  • Process control 

  • Historical trends 

  • Alarm history 

  • Data logging 

  • Automated reports 

  • Remote access 

  • User permissions

CrystalVision also provides on-site commissioning, operator training and ongoing technical support according to the needs of each project.

Control & Automation 

Practical control systems designed around the process 

CrystalVision develops control and automation systems for industrial, agricultural, aquaculture and research applications. 

We design the control layer around the actual process — from sensors and PLC logic to HMI/SCADA, alarms, data logging and remote monitoring. 

Our systems can be developed for new installations or used to modernize and expand existing facilities. 

Reliable control. Clear information. Practical operation.

Control Systems We Build 

CrystalVision designs and programs control systems for individual machines, process systems and complete facilities. 

Depending on the application, the system may include: 

  • PLC programming and I/O architecture 

  • Sensors and instrumentation 

  • Motor, pump and valve control 

  • HMI and SCADA 

  • Alarm management 

  • Historical data and trends 

  • Remote monitoring and control 

The control strategy is developed according to the process and operating requirements rather than around a specific PLC manufacturer or technology. 

​​

​

Process Control & Instrumentation 

Reliable automation starts with accurate information from the field. 

CrystalVision selects and integrates sensors for parameters such as: 

  • Temperature 

  • Pressure 

  • Level and flow 

  • Weight 

  • Humidity 

  • pH 

  • Dissolved oxygen 

  • Conductivity and salinity 

  • Soil and water parameters 

  • Analytical measurements 

  • Other process-specific values 

Measurements can be used for monitoring, alarms or directly within the control logic. 

Based on these inputs, the system can automatically operate pumps, valves, motors, variable-frequency drives, heaters, cooling systems, dosing equipment and other field devices. 

​​​

​

 

Control Logic, Safety & Reliability 

A good control system must handle both normal operation and unexpected conditions. 

Depending on the project, CrystalVision develops: 

  • Automatic operating sequences 

  • Setpoint-based control 

  • Equipment interlocks 

  • Permissive conditions 

  • Watchdog functions 

  • Fault handling 

  • Minimum and maximum operating limits 

  • Defined fallback states 

The objective is to make system behavior predictable and safe when sensors, equipment or communications do not behave as expected.
