config MB_QUEUE_LENGTH
    int "Modbus serial task queue length"
    range 0 200
    default 20
    help
        Modbus serial driver queue length. It is used by event queue task.
        See the serial driver API for more information.
        
config MB_SERIAL_TASK_STACK_SIZE
    int "Modbus serial task stack size"
    range 768 8192
    default 2048
    help
        Modbus serial task stack size for event queue task. 
        It may be adjusted when debugging is enabled (for example).

config MB_SERIAL_BUF_SIZE
    int "Modbus serial task RX/TX buffer size"
    range 0 2048
    default 256
    help
        Modbus serial task RX and TX buffer size for UART driver initialization.
        This buffer is used for Modbus frame transfer. The Modbus protocol maximum 
        frame size is 256 bytes. Bigger size can be used for non standard implementations.
        
config MB_SERIAL_TASK_PRIO
    int "Modbus serial task priority"
    range 3 10
    default 10
    help
        Modbus UART driver event task priority. 
        The priority of Modbus controller task is equal to (CONFIG_MB_SERIAL_TASK_PRIO - 1).

config MB_CONTROLLER_SLAVE_ID_SUPPORT
    bool "Modbus controller slave ID support"
    default n
    help
        Modbus slave ID support enable. 
        When enabled the Modbus <Report Slave ID> command is supported by stack.

config MB_CONTROLLER_SLAVE_ID
    hex "Modbus controller slave ID"
    range 0 4294967295
    default 0x00112233
    depends on MB_CONTROLLER_SLAVE_ID_SUPPORT
    help
        Modbus slave ID value to identify modbus device 
        in the network using <Report Slave ID> command.
        Most significant byte of ID is used as short device ID and
        other three bytes used as long ID.

config MB_CONTROLLER_NOTIFY_TIMEOUT
    int "Modbus controller notification timeout (ms)"
    range 0 200
    default 20
    help
        Modbus controller notification timeout in milliseconds. 
        This timeout is used to send notification about accessed parameters.

config MB_CONTROLLER_NOTIFY_QUEUE_SIZE
    int "Modbus controller notification queue size"
    range 0 200
    default 20
    help
        Modbus controller notification queue size. 
        The notification queue is used to get information about accessed parameters.

config MB_CONTROLLER_STACK_SIZE
    int "Modbus controller stack size"
    range 0 8192
    default 4096
    help
        Modbus controller task stack size. The Stack size may be adjusted when 
        debug mode is used which requires more stack size (for example).    

config MB_EVENT_QUEUE_TIMEOUT
    int "Modbus stack event queue timeout (ms)"
    range 0 500
    default 20
    help
        Modbus stack event queue timeout in milliseconds. This may help to optimize
        Modbus stack event processing time.
        
config MB_TIMER_PORT_ENABLED
    bool "Modbus stack use timer for 3.5T symbol time measurement"
    default y
    help
        If this option is set the Modbus stack uses timer for T3.5 time measurement. 
        Else the internal UART TOUT timeout is used for 3.5T symbol time measurement.

config MB_TIMER_GROUP
    int "Modbus Timer group number"
    range 0 1
    depends on MB_TIMER_PORT_ENABLED
    default 0
    help
        Modbus Timer group number that is used for timeout measurement. 

config MB_TIMER_INDEX
    int "Modbus Timer index in the group"
    range 0 1
    depends on MB_TIMER_PORT_ENABLED
    default 0
    help
        Modbus Timer Index in the group that is used for timeout measurement.
