| |
| ============================================================== |
| Apache PLC4X 0.8.0 |
| ============================================================== |
| |
| This is an ordinary PLC4X release, containing changes that |
| accumulated over time. It doesn't have an explicit focus on |
| a particular topic. |
| |
| New Features |
| ------------ |
| |
| - The KNXnet/IP Driver now supports writing of values. |
| |
| - The Modbus driver now supports more common notations of |
| Modbus addresses using a pure-numeric notation. |
| |
| - The ADS, KNX, Modbus, S7 and simulated drivers have been |
| updated to support the IEC 61131-3 data-types. |
| |
| - We are now including PLC4Go as PLC4X implementation in |
| the programming language Go(lang) |
| |
| - Integration with the Milo OPC UA Server is now available. |
| |
| - Kafka Connect workers have been updated source and sink connectors |
| are now included. |
| |
| Incompatible changes |
| -------------------- |
| |
| - The syntax of the S7 addresses changed slightly allowing to |
| provide a string length. Without this, a STRING datatype will |
| read 254 characters, by adding the size in round brackets to |
| the type name will use the specified number. |
| |
| Examples: |
| |
| Read one String which is max 10 chars long: |
| %DB2:30:STRING(10) |
| |
| Read an array of 3 Strings where each is max 10 chars long: |
| %DB2:30:STRING(10)[3] |
| |
| - The PLCValue types have been refactored to align with the types |
| defined in IEC 61131-3 (https://en.wikipedia.org/wiki/IEC_61131-3) |
| directly using the older Java types (PlcBoolean) is no longer |
| possible. |
| |
| Bug Fixes |
| --------- |
| |
| A lot of testing was done regarding the IEC 61131-3 data-types. |
| This resulted in numerous bugfixes in many protocols. |
| |
| PLC4X-132 [S7] Communication to S7 PLC dies in some situations |
| PLC4X-206 When writing short values exceptions are thrown |
| while preparing the write request. |
| PLC4X-207 No registered handler found for message TPKTPacket[], |
| using default decode method - Communication with S7 |
| and Modbus device hangs |
| PLC4X-209 [S7] When writing INT and DINT values the Write |
| operation fails with an internal error |
| PLC4X-210 [KNX] When running a KNX Tunneling Subscription |
| for a longer time there are packets that kill |
| the connection |
| PLC4X-211 PlcValues seem to always return "true" on the |
| isXYZ" checks. |
| PLC4X-212 When writing multiple values in one request the |
| item status is not correctly set |
| PLC4X-213 [Modbus] The Modbus driver doesn't handle error |
| responses gracefully |
| PLC4X-214 [Modbus] Holding register addresses have an offset |
| of 1 (Not reading the correct address) |
| PLC4X-215 Drivers using the BaseOptimizer |
| (SingleFieldOptimizer) don't handle error responses |
| gracefully |
| PLC4X-218 [Scraper] After stopping the scraper still the |
| statistics are logged and the application doesn't |
| terminate |
| PLC4X-239 Read DTL (Date and Time) |
| PLC4X-240 Protocol error in reading string |
| PLC4X-246 S7 driver hangs on read |
| PLC4X-245 [Modbus] Apache NiFi processor throws |
| java.io.IOException after a while |
| PLC4X-255 Kafka Connector Source Task doesn't block within poll() |
| resulting in high CPU usage. |
| PLC4X-261 Pooled connection manager returns a connection that isn't |
| connected in some situations. |
| PLC4X-272 When splitting up large requests, too big sub-requests |
| are generated (S7) |
| PLC4X-256 ReadBuffer truncate last byte of even small payloads |
| PLC4X-262 Error in reading Array |
| PLC4X-270 Ads driver does not accept double-digit array indexes |
| |
| ============================================================== |
| Apache PLC4X 0.7.0 |
| ============================================================== |
| |
| This version is the first after a major refactoring of the driver |
| core. All previous driver versions are now considered deprecated |
| and have been replaced by versions using the new driver structure |
| and generated driver codebase. |
| |
| New Features |
| ------------ |
| |
| - Drivers now support structured types using PlcValues |
| - The EIP (EtherNet/IP) driver no longer requires an external |
| library and is implemented fully in the PLC4X project |
| - The Modbus driver no longer requires an external library |
| and is implemented fully in the PLC4X project |
| - The new S7 Driver supports writing multiple entries in one |
| request (The API allowed this from the beginning now not |
| every item is wrapped in a single request. It should bring |
| significant performance gains when writing multiple vlaues) |
| - S7 Driver now supports String datatypes. |
| - OSGi : Implementation of Drivers/Transports as OSGi services |
| to be able to use them in an OSGi container. |
| - New Firmata protocol driver |
| |
| Incompatible changes |
| -------------------- |
| |
| - Due to the refactoring of the driver core there might be issues |
| running drivers built against older core versions. |
| - This version doesn't provide a Beckhoff AMS/ADS driver as this |
| driver is still being ported to the new mspec format. |
| - All drivers connection strings now follow the same pattern: |
| {protocol-code:(transport-code:)?//{transport-config}(?{params})? |
| Please check the drivers documentation on our website: |
| https://plc4x.apache.org/users/protocols/s7.html |
| - The karaf-feature modules are removed as the drivers now all |
| provide both a feature.xml as well as a `kar` bundled archive |
| |
| Bug Fixes |
| --------- |
| |
| PLC4X-174 UDP Transport does not accept ports containing 0 |
| PLC4X-134 S7 is terminating the connection during handshake |
| PLC4X-192 Support for conversion of complex connection string |
| parameters |
| |
| ============================================================== |
| Apache PLC4X 0.6.0 |
| ============================================================== |
| |
| This is the last release of PLC4X with the "handwritten" drivers. |
| This Minor release will thus receive updates and fixes until |
| most users have switched to 0.7 and above (with generated drivers). |
| |
| If you are using the S7 Driver you should update to this Version |
| as the critical (memory leak) bug PLC4X-163 is fixed. |
| |
| New Features |
| ------------ |
| - PLC4X-168 A shorter S7 Field Syntax is Introduced. |
| This release contains no further features and mostly stabilization. |

| |
| 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 |
