1.2.3

LogixDriver

• 🐛 fixed issue with bit-level access to integers inside nested structs #170

1.2.2

CIPDriver

• ✨ added support for string CIP paths in generic_message for route_path
• 🐛 fixed bug where errors during discovery prevent any results from being returned (#167)
• 🐛 fixed issue where get_module_info would always use first hop in path instead of the last

LogixDriver

• 🐛 fixed issue with multi-request message size tracking being off by 2 bytes (#168)
• 🐛 fixed issue with AOI structure handling with > 8 BOOL members being mapped to types larger than a USINT (SISAutomationIMA)

1.2.1

• ✨ added ability to configure custom logger via the configure_default_logger function

1.2.0

• 🐛 fixed issue with logging configuration (#148)

• 📝 misc. documentation updates

LogixDriver

• 🐛 fixed issue with writing a tag multiple times failing after the first write (#158 )
• ✨ added tags_json property (#141)

SLCDriver

• 🐛 fixed issue with parsing IO addresses (#137)
• ⚡ improved address parsing speed by pre-compiling regex

1.1.1

LogixDriver

• 🐛 fixed read/write errors by preventing program-scoped tags from using instance ids in the request

1.1.0

LogixDriver

• 🐛 fixed bugs in handling of built-in types (TIMER, CONTROL, etc)
• 🐛 fixed bugs in structure tag handling when padding exists between attributes
• ✨ changed the meaning of the element count for BOOL arrays
  • Previously, the {#} referred to the underlying DWORD elements of the BOOL array.
    A BOOL[64] array is actually a DWORD[2] array, so array{1} translated to BOOL elements
    0-31 or the first DWORD element. Now, the {#} refers to the number of BOOL elements. So
    array{1} is only a single BOOL element and array{32} would be the 0-31 BOOL elements.
  • Refer to the documentation for limitations on writing.

1.0.1

• 🐛 Fixed incorrect/no error in response Tag for some failed requests in a multi-request
• ♻️ Minor refactor to status and extended status parsing

1.0.0

Changes

• ✨ New type system to replace the Pack and Unpack helper classes
  • New types represent any CIP type or object and allow encoding and decoding of values
  • Allows users to create their own custom types
  • 💥 [Breaking] generic_message replaced the data_format argument with data_type, see documentation for details.
• ✨ Added a new discover() method for finding Ethernet/IP devices on the local network
• ✨ Added a configure_default_logger method for simple logging setup
  • Packet contents are now logged using a custom VERBOSE level
• 🎨 Internal package structure changed.
• ♻️ Lots of refactoring, decoupling, etc
• ✅ Increased test coverage
• 📝 New and improved documentation
  • 🚧 Still a work-in-progress

LogixDriver Changes

• 🚩 Upload of program-scoped tags is now enabled by default
  • Use init_program_tags=False in initializer to upload controller-scoped only tags
• 💥 Removed the init_info and micro800 init args and the use_instance_ids property
  • These have all been automatic for awhile now, but were left for backwards compatibility
  • If you need to customize this behavior, override the _initialize_driver method

1.0.0 Beta Release

This is a beta release for the new V1 release. This release is intended only for test purposes and as a draft for the stable 1.0.0 release.

Major Changes:

• new type system, removed the Pack and Unpack helper classes
  • old: Pack.uint(100) -> new: UINT.encode(100)
  • types as classes that can encode and decode any elementary or structured data type
  • when parsing the tag list a type is created for every tag to encode or decode their value
  • can create custom types for any struct, array, etc
  • replaces the data_format arg for generic messaging
  • TODO: full documentation on how to use types. Examples have been updated for now.
• Internal package structure changed, may break imports if not importing from top level package
• Lots of refactoring, decoupling, etc improvements internally, helping improve testability
• added a configure_default_logger method for simple logging setup
• packet contents are now logged with a custom VERBOSE log level
  • removed the RequestPacket.VERBOSE_DEBUG option used previously
  • improved the packet formatting too to look similar to wireshark
• [BREAKING] generic_message now uses the new type system. The data_format arg was replaced with data_type.
• added new discover() method to discover Ethernet/IP devices on the local network

LogixDriver

• upload of program scoped tags is now on by default, use init_program_tags=False in initializer to disable.
• removed the init_info and micro800 init args, also removed the use_instance_ids property
  • feature selection is all automatic now, if it needs to be customized, subclass and overwrite the _initialize_driver method

0.12.0

• added support for backslashes in the PLC paths
• improved parsing of PLC paths
• improved testing

LogixDriver

• added support for writing structures using dicts
• added get_tag_info method for looking up data type and other information about a tags
• added new data_type_name for all tag definitions
  • makes filtering lists simpler due to differences between struct and atomic tags
• fixed bit writes >.31 for LINTs
• fixed some issues with writing boolean arrays longer than 32 elements
• fixed issues when duplicate tags are in the same read/write call
  • especially with duplicate bit level writes having unexpected results
• improved packet size estimation

SLCDriver

• fixed bit level writing in SLCDriver
