TwinCAT 3.1 Build 4026

Also known as: TC3.1.4026, Build 4026

German: TwinCAT 3.1 Build 4026

In industrial automation, TwinCAT 3.1 Build 4026 is a release line of Beckhoff's TwinCAT 3 software that introduced installation and management of TwinCAT components as individual packages through the TwinCAT Package Manager.

In one sentence

TwinCAT 3.1 Build 4026 is the TwinCAT 3 release line that installs and manages components as packages via a package manager.

Example

With Build 4026, an engineer installs only the packages a project needs and records the package list, so a second IPC can be set up identically.

How it applies

  • Engineering: Package-based installation changes how engineering and runtime systems are set up and updated. Teams define which packages and versions make up their standard environment.
  • Configuration management: A list of packages and versions describes the installed software precisely and can be stored with the project. That supports reproducible setups and a clear Configuration baseline.
  • Migration: Projects from earlier builds can be migrated, but libraries, function packages and licenses need checking. Test migrated projects on the target build before delivery.
  • Documentation: Update installation and service instructions for the package-based process; procedures written for earlier builds no longer apply unchanged. Record package lists per machine.

Build 4026 vs. Build 4024

TwinCAT 3.1 Build 4024 uses a classic setup; Build 4026 uses packages. The runtime concepts remain, but installation, updates and some tool behavior differ.

Keep in mind: product names and features change. Check build features and release notes against the vendor's current documentation.
