Zeus PLC runtime 0.1.0.13 - third-party source code
================================================

The Zeus PLC runtime (zeus-plcd) on this controller is proprietary software of
Zeus Automation / Biosoft Engineering Ltd. It links the following open-source
components, whose complete source code, exactly as used, is in this archive:

  SOEM 1.4.0   - Simple Open EtherCAT Master
                 GPL-2.0 with a linking exception (see SOEM/LICENSE).
                 Unmodified. The exception keeps the rest of the runtime
                 proprietary; SOEM's own source is provided here as its
                 licence requires.
  open62541 1.4.6 (amalgamated) - OPC UA
                 Mozilla Public License 2.0 (see open62541-amalgamation/).
                 Unmodified.

The runtime also uses the operating system's OpenSSL (Apache-2.0) as a shared
library; it is part of Debian and its source is available from Debian.
