UP Arror - Increase 40,001 by 1
Down Arror - Decrease 40,001 by 1
FYI: Key Q pressed.
FYI: Quit- Copy CASModbusStack_Win32_Debug.dll, CASModbusStack_Win32_Release.dll, CASModbusStack_x64_Debug.dll, and CASModbusStack_x64_Release.dll from the CAS Modbus Stack project into the /bin/ folder.
- Use Visual Studios 2019 to build the project. The solution can be found in the /ModbusTCPSlaveExampleCSharp/ folder.
Note: The project is automaticly build on every checkin using GitlabCI.
