  • Optimized an issue with non-responding Modbus TCP servers.

1.1.0 (2021-04-30)

Added (1 change)

  • Extensions to convert from/to naive data types have a parameter to inverseRegisters order. (by @Luke092) (Closing Issue #15 more precisely)

Fixed (1 change)

  • Better async behaviour for serial client.

Updated (2 changes)

  • Updated to C# 9.0
  • Updated packages

1.0.4 (2021-04-13)

Added (1 change)

  • Extension to convert from/to string enhanced by switch to flip bytes (endianness). (Closing Issue #15)

1.0.3 (2021-03-29)

Fixed (1 change)

  • Resolved null reference errors while reconnecting (TCP and Serial). (Closing Issue #14)

Added (1 change)

  • Extensions to convert values back to ModbusObjects are now available.

1.0.2 (2020-12-08)

Fixed (1 change)

  • Removed a potential dead-lock scenario when disconnecting while on reconnect.

Added (1 change)

  • Modbus clients have a optional CancellationToken on Connect() and Disconnect().

1.0.1 (2020-11-30)

Fixed (1 change)

  • The Modbus TCP client on unix systems creates an IOException on connection loss - catch that exception instead of the EndOfStreamException.

1.0.0 (2020-11-28)

Fixed (3 changes)

Client
  • The Modbus TCP client will now recognize (again) a connection close from the remote and start the reconnect cycle
Server
  • The Modbus TCP server recognizes the connection close from the client as well and terminate the running tasks.
  • The Modbus TCP server catches the rising NotImplementedExceptions and will not crash anymore on invalid requests.

Added (5 changes)

  • Added this changelog.
  • Added a ModbusObject as base class for Coils, DiscreteInputs and Registers. The property Type of ModbusObjectType will tell you the actual meaning.
    For naming reasons the old classes are still present and used.
  • *.snupkg (Debug Symbols) for the NuGet packages are available on my Gitlab.
  • New package AMWD.Modbus.Proxy
    • TCP to TCP can be used when a remote device only accepts one connection but multiple clients want to request the information (or as Gateway [on a NAT device]).
    • TCP to Serial can be used to bring a Modbus RTU (RS485) device into your local network.
  • Added a custom console logger to the console demo application.

Changed (5 changes)

  • The Value property of all structure classes is replaced by RegisterValue for 16-bit values ([Holding | Input] Register) and BoolValue for 1-bit values (Coil, DiscreteInput).
  • All servers and clients can use an ILogger implementation for detailed logging in the instances.
  • Using more TimeSpan for timeouts instead of integer values with different meanings (seconds, milliseconds?!?).
  • Updated Gitlab CI procedure for automatic deployment to NuGet.org.
  • Code cleanup and C# 8.0

Removed (1 change)

  • git attributes not needed and therefore deleted.
  • FakeSynchronizationContext was never used.

0.9.10 (2020-07-07)

Fixed (1 change)

0.9.9 (2020-06-29)

Fixed (2 changes)

  • Fixed an issue where the serial client crashed during a request.
  • SemVer tagging only allowes 3 sections (major, minor, patch).

  • More specific evaluation of property ranges for the serial client.
  • Added license information to the nuget packages.

Fixed (1 change)

  • Fixed an issue with an incompatible buffer size on the serial client.

0.9.8 (2020-06-19)

Fixed (2 changes)

  • Requests from clients can be cancelled with a CancelleationToken.
  • Read/Write async on serial connections is now available.
    (The .NET implementation ignores cancellation tokens)

Added (3 changes)

  • New package to create Modbus request proxies.
    Needed to translate requests from TCP to Serial and vice versa or to make a device with only one (1) connection at a time available to multiple clients.
    Note: Not deployed on NuGet.org.
  • Enhanced the console demo application to provide a server.
  • Modbus servers have custom request handlers.

Changed (2 changes)
