One engineering tool. One runtime. No separate PLC.
Logivyx combines a full HMI/SCADA designer with an embedded Soft PLC. Two products, one project file: Logivyx Studio for engineering and Logivyx Runtime for the deployed operator station.
HMI & Visualisation
A desktop-class designer for operator screens, with the data, security and reporting an industrial HMI is expected to have — ready out of the box.
Screen Designer
Multi-screen canvas with shared zone grid, auto display sizing, Master Template overlay, Z-order, alignment and copy/paste.
Widget Library
Gauges, trends, dual-axis and X-Y charts, grid views, switches, sliders, multi-state lamps — every widget tag-bound.
Process & P&ID Graphics
Animated tanks, valves, motors/pumps, pipes with flow, conveyors and pistons, plus connectable P&ID symbols.
Alarm Management
Alarm banner on every screen, alarm list dialog, and an auto-alarm generator built from the tag list.
Data Logging & Recipes
Trigger-based logging to SQLite with unique batch keys and CSV export; multiple recipe profiles with an operator recipe widget.
Reports
Print-ready A4 / Letter layouts; auto-export to PDF on a trigger tag, one file per batch.
Security & Users
User groups, hashed passwords, login-gated Run mode and audit-friendly current-user tags.
Vision, Twin & Remote View
USB camera widget with vision processing, Digital Twin visualisation, and a browser / Android web viewer.
Logic & Embedded Soft PLC
The control layer that replaces a separate PLC. Program in the IEC 61131-3 style your engineers already know, and run it in the same runtime as the HMI.
Structured Text
Full editor with function palette, user UDTs and Function Blocks.
Ladder Diagram
Graphical rung editor with contacts, coils and FB boxes; generates ST.
Sequence Designer
Step / transition flow with live step highlighting and Excel import.
(* Fill control *) fillTmr(IN := Start, PT := T#5s); IF Level < SP AND NOT Fault THEN Valve_Open := TRUE; ELSE Valve_Open := FALSE; END_IF; Out := SCALE(Raw, 0, 27648);
Soft PLC Runtime Engine
Cyclic scan: input refresh, execution, output write-back. Scan-time and overrun monitoring, fault isolation per scan, retentive variables across restarts.
Standard Function Library
TON, TOF, TP, CTU, CTD, edge triggers, PID, SCALE/LIMIT, maths, trig, strings and type conversions.
Motion Control
PLCopen-style blocks for CiA 402 drives: MC_Power, MC_Home, MC_MoveAbsolute / Relative / Velocity, MC_Stop, MC_Reset.
Code Generators
I/O mapping, analog scaling, alarm logic, recipes and settings screens from tag lists and Excel sheets.
Diagnosis & Cross-Reference
Online logic and I/O diagnosis, watch window with forcing, project-wide tag cross-reference.
PLC Interoperability
Export to Rockwell Studio 5000 (L5X) and Siemens TIA Portal (SCL); import Logix L5X projects.
Configure forms. Draw diagrams. Import spreadsheets.
Drag & drop screens
Build screens from a palette; bind tags by picking from the browser.
Excel tag & I/O import
Tags, I/O lists and sequences from Excel, L5X or PLC exports in one click.
Form-based data services
Logging, recipes, reports, SQL and alarms through dialogs — no scripting.
Point-and-click behaviour
Data transfers, popups, navigation, visibility and security per widget.
AI-assisted engineering
A built-in assistant helps draft logic and screens.
Built-in simulator
Test screens and logic together before any hardware arrives.
