1.0.0 #

  • Initial version.

2.0.0 #

  • Simplified read and write method:- Now only two methods are provided for reading and writing (i.e. read and write) as opposed to 6 methods previously.
  • Intuitive method names for object creation. "start" method creates object & initializes all resouces. "stop" method shuts down all resources & disconnects all TCP connections.
  • Asynchronous isStoppedAsync method to check whether object is stopped.
  • Bug fixes.

2.0.1 #

  • Updated README.md file
  • Provided docstrings
  • updated modbus_slave.py file

2.1.0 #

  • Updated README.md file
  • Added two more fields isReadResponse and isWriteResponse in class SlaveResponseConnectionError as well as class SlaveResponseTimeoutError

2.1.1 #

  • Bug fixes:- In case of Error Response, field isReadResponse/isWriteResponse is true and readValue/writeValue is null of object of class SlaveResponseDataReceived is true.

2.1.2 #

  • Bug fixes:-
    • Inside Worker Isolate :- When UserRequestShutdown is received in worker isolate, then all sockets are now closed using await socket.close() instead of socket.destroy().
    • Inside Main Isolate:- When SlaveResponseShutdownComplete is received in main isolate, then receive port of main isolate is also closed.

2.1.3 #

  • Bug fixes :-
    • socket.destroy() is not used
      • In worker isolate, await socket.close() is used instead of socket.destroy().
      • This is done because in few scenarios in case of hard socket closing from server side, network isolate was getting killed.
    • Extra getter maximumNumberOfTCPConnectionsAllowedprovided for object of class ModbusMaster. This is done so that users explicity know about maximum how many concurrent TCP connections can be made.
    • Refactoring changes

2.1.4 #

  • Message framing was done for message received from socket
    • When multiple Modbus ADU was received from socket as single Uint8List, then those messages were getting dropped, as multiple ADU together were more than length as per 1st ADU
    • Created method splitMessageFromSocketIntoMultipleModbusADU to split message incoming into multiple ADU.
