| ============================================================== |
| Apache PLC4X 0.4.0 |
| ============================================================== |
| |
| This is the first release of Apache PLC4X as top-level project. |
| |
| New Features |
| ------------ |
| |
| - The PlcConnection now supports a `ping` method to allow checking if an existing connection is still alive. |
| - Support of the OPC-UA protocol with the `opc-ua-driver`. |
| - Other Languages Support: |
| -- Added first versions of a C# .Net PLC4X API (`plc4net`) |
| -- Added first versions of a Python PLC4X API (`plc4py`) |
| - Added an Interop server which allows to relay requests from other languages to a Java Server |
| |
| Incompatible changes |
| -------------------- |
| |
| - ElasticSearch example was updated to use ElasticSearch 7.0.1, this might cause problems with older Kibana versions. |
| |
| Bug Fixes |
| --------- |
| |
| |
| ============================================================== |
| Apache PLC4X (incubating) 0.3.1 |
| ============================================================== |
| |
| This is a bugfix-release, that fixes some problems with S7 driver. |
| |
| Bug Fixes |
| --------- |
| |
| - The S7 driver didn't correctly handle "fill-bytes" in multi-item read-responses and multi-item write-requests |
| - PLC4X-83: fixed NPE when reading odd-length array of one-byte base types |
| - PLC4X-82: renamed flags "F" to Siemens Standard "M" (Marker) |
| - PLC4X-84: Fixed a bug in the DefaultS7MessageProcessor which didn't correctly merge together split up items |
| |
| |
| ============================================================== |
| Apache PLC4X (incubating) 0.3.0 |
| ============================================================== |
| |
| This is the third official release of Apache PLC4X. |
| |
| Some new features have been added (e.g. plc-scraper) multiple |
| new integrations are included (apache-karaf, apache-calcite) |
| and a lot of (technical) refactoring has been done to prepare |
| future work on adapters in different languages. |
| |
| 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 |
| --------- |
| |
| PLC4X-75 Fixing dependency to the wrap url-handler |
| PLC4X-76 When receiving responses with more than 512 byte, |
| the IsoOnTcp protocol doesn't work |
| PLC4X-77 When the last item in a request is a DINT, the |
| DefaultS7MessageProcessor dies |
| PLC4X-78 Write operations seem to fail |
| - Fixed a Bug where S7 was not able to read arrays. |
| |
| |
| ============================================================== |
| Apache PLC4X (incubating) 0.2.0 |
| ============================================================== |
| |
| This is the second official release of Apache PLC4X. |
| |
| Especially have we addressed all issues reported during |
| our first release, that were of non-technical nature. |
| These were tracked in: |
| |
| PLC4X-60 Fix findings by the last release |
| |
| New Features |
| ------------ |
| A new connection-pool was added, which allows automatic |
| pooling and reuse of PLC connections. |
| |
| A new OPM module was added, which allows JPA like read- |
| communication using POJOs, very similar to JPA. |
| |
| A stub of a new driver for the Emerson DeltaV protocol |
| has been added, but is not yet a fully functional PLC4X |
| driver. This is also a first test of our new `passive- |
| mode-driver` concept. |
| |
| Incompatible changes |
| -------------------- |
| |
| We have refactored the API in order to eliminate the |
| need of passing `x-requests` to `x-methods` and added |
| an `execute` method to each request type. This greatly |
| simplifies the client code. However this requires |
| refactoring of applications using the direct PLC4X API. |
| |
| Miscellaneous changes |
| --------------------- |
| |
| We have increased the test coverage greatly and fixed |
| a lot of little errors we found on the way. |
| |
| Known Issues |
| ------------ |
| |
| Bug Fixes |
| --------- |
| |
| PLC4X-56 [S7] S7Field does not recognize addresses |
| with numElements present |
| PLC4X-57 [S7] Response for address with numElements |
| contains only first item |
| PLC4X-61 Installation fails plc4j-protocoll-ethernetip |
| needs license |
| PLC4X-62 Modbus results deliver null-Value due to missing |
| implementation of getShort, getLong ... |
| |
| |
| |
| ============================================================== |
| Apache PLC4X (incubating) 0.1.0 |
| ============================================================== |
| |
| This is the first official release of Apache PLC4X. |
| It contains drivers for the following protocols: |
| - Siemens S7comm (0x32) |
| - Beckhoff ADS |
| - Modbus |
| - EtherNet/IP |
| |
| However the Siemens driver definitely is the most |
| mature driver, the rest should be treated experimental. |
| |
| New Features |
| ------------ |
| |
| PLC4X-29 [S7] Implement PDU Fragmentation |
| PLC4X-39 Extend the Edgent integration with the new Subscription features of PLC4X |
| |
| Incompatible changes |
| -------------------- |
| |
| - NONE - |
| |
| Miscellaneous changes |
| --------------------- |
| |
| - NONE - |
| |
| Known Issues |
| ------------ |
| |
| - NONE - |
| |
| Most drivers should be treated experimental and are not near production ready. |
| The S7 driver is probably the furthest implemented and tested driver and hereby can be |
| considered to be the most mature. |
| |
| Bug Fixes |
| --------- |
| |
| PLC4X-20 Jacoco doesn't seem to be working at all |
| PLC4X-21 Code coverage doesn't seem to work |
| PLC4X-47 S7 driver silently ignores surplus ReadRequestItems |
| PLC4X-48 S7 driver failes to parse response with multiple items |
