Updated Nov 27, 2025
Explain
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.
Core Features
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
Basic Concepts Overview
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
Project Structure
Main Citect project files (.CFG, .PRJ)
Cicode script files (.CI)
Tag database and alarm configuration
HMI screen configuration files
External database or OPC configuration
