Firmware releases
Release strategy
- Each year comes a long-term support (LTS) release which will be supplied with security enhancement and bug fixes (if necessary).
- Each quarter follows a feature release with additional capabilities.
- Those feature releases always contain the former features in full, so you can adapt your projects to new releases easily.
- Newer features will be included in the following LTS release.
This gives you the opportunity to develop your application or app always with the latest features.
Note: For applications, Phoenix Contact recommends to depend on LTS releases only, especially for applications related to certain approvals which always are examined for LTS releases only. For details, see the according Applications facet on PLCnext Control product pages.
Release history
The PLCnext Technology adventure began in 2016 with an Early Adopters' phase, driven by the PLCnext Control AXC F 2152 with firmware release version 1.0 and the former PC Worx Engineer, a derivative of the well-known PC Worx Automation Suite of Phoenix Contact.
In 2018, the PC Worx Engineer has become the PLCnext Engineer, which is the general engineering tool for PLCnext Technology related programming.
Beginning in late 2018, the above mentioned release strategy was adopted to address the demand for an agile development.
