Previous Releases

0.3.0 Official source release [ SHA512 ] [ ASC ]

New Features
  • Object PLC Mapping (OPM) now has a Alias Registry to allow variable substitution at runtime and write support

  • New module plc-scraper for applications that have to scrape a lot of sps fields with high frequency

  • New integration apache-karaf to enable plc4j in a karaf runtime environment

Incompatible changes
  • The 'plc4j-core' module has been merged into 'plc4j-api'. So there is no 'plc4j-core' module anymore. Just remove that dependency.

  • The driver artifact names have changed so if you were using a plc4j-protocol-{name} you now need to change this to plc4j-driver-{name}

Bug Fixes
  • Fixing dependency to the wrap url-handler

  • When receiving responses with more than 512 byte, the IsoOnTcp protocol doesn’t work

  • When the last item in a request is a DINT, the DefaultS7MessageProcessor dies

  • Write operations seem to fail

  • Fixed a Bug where S7 was not able to read arrays.

0.2.0 Official source release [ SHA512 ] [ ASC ]

Changes:
  • Changed API: instead of passing request object to read({read-request}), write({write-request}) or subscribe({subscribe-request}) methods now the execute() method is called on the request itself

  • New Connection Pool component

  • New OPM (Object PLC Mapping) component (JPA for PLCs)

  • Bug fixes
