ETAP 21 ETAP 21 from the vendor is a production-grade industrial control engineering environment built for day-to-day industrial work. Instead of juggling disconnected utilities, teams plan, build, test, and document controller programming projects inside one environment, which shortens learning curves and keeps every project artifact in a single, traceable place.
Core Functions. Security features include authenticated access, signed project handling, and controlled communication paths aligned with modern industrial-security practice. Online monitoring with variable forcing, cross-reference search, and trend charts makes commissioning and fault-finding systematic instead of guesswork. Motion integration programs axes, cam profiles, and homing sequences alongside standard logic, with coordinated control for demanding machines. Network configuration covers industrial Ethernet, fieldbus, and serial integration with built-in device description and parameter tools. Reusable function blocks and libraries capture proven logic, enforce company standards, and cut repeat engineering on machine families. Structured tag databases keep controller, HMI, and drive references consistent, eliminating re-entry and the mismatches it causes. Version and change management compares revisions, tracks modifications, and protects installed programs with controlled download procedures. Programming in ladder diagram, function block diagram, and structured text gives each part of the application the language that fits it best, inside one project. The workspace remains customizable, so each discipline can arrange the tools it uses most within quick reach. Import and export functions keep collaboration with customers, suppliers, and partner engineering offices straightforward and loss-free. Automated checks validate projects against configurable rules before release, catching inconsistencies that reviews tend to miss. Support and update channels remain available throughout the product lifecycle, keeping installations current and secure. Performance profiling and reporting help teams understand where engineering time is spent and where processes can be tightened further. Documentation, training material, and example projects are included to shorten onboarding for new team members. Project templates and reusable libraries standardize repeat work, so every new job starts from proven material instead of a blank page. Integration interfaces connect the environment with surrounding engineering and enterprise systems, avoiding manual data transfers.
New in Version 21. Version 21 modernizes the licensing experience, simplifies installation, and continues the series’ compatibility commitments. Version 21 refines stability across the board and rolls in the accumulated fixes from earlier maintenance releases. New in version 21: faster project open and save on large programs, more responsive editors, and smoother device integration.
Supported Systems. System requirements: Windows 10 or 11, 64-bit, 8 GB RAM minimum, 10 GB free disk space, and administrator rights for installation and device communication.
