Learn CITECT-SCADA-SCRIPTING with Real Code Examples

Citect SCADA scripting allows automation beyond graphical configuration of SCADA objects.

Supports structured programming with variables, loops, conditionals, and functions.

Enables dynamic control of tags, alarms, historical data logging, and HMI screens.

Facilitates integration with PLCs, databases, and external systems via OPC or native drivers.

Widely used in industrial automation for process control, monitoring, and visualization.

IF/ELSE, FOR, WHILE constructs for logic control

User-defined functions for modular scripting

Tag read/write access for real-time control

Alarm and event scripting

Integration with external systems via COM, OPC, or database connections

Tag - variable representing process data

Event - trigger that executes a script

Alarm - condition monitored and reported via SCADA

Function - reusable block of script code

Screen Object - HMI element manipulated via script

Main Citect project files (.CFG, .PRJ)

Cicode script files (.CI)

Tag database and alarm configuration

HMI screen configuration files

External database or OPC configuration

Define automation or visualization task

Identify relevant tags and events

Write Cicode script for logic and control

Link scripts to HMI screens and events

Test, debug, and optimize in simulation/runtime

Beginner: basic tag manipulation and simple calculations

Intermediate: conditional alarms and event handling

Advanced: dynamic HMI updates and process logic

Expert: multi-system integration and complex automation

Architect: enterprise-wide SCADA scripting and reporting

Cicode vs PLC Ladder Logic: SCADA-centric vs controller-centric

Cicode vs VBScript/JavaScript: SCADA runtime integration

Cicode vs Python: performance vs flexibility in SCADA

Cicode vs KAREL: general process vs CNC/robot automation

Cicode vs standard HMI configuration: dynamic scripting vs static screens
