Initialize the MBX slave object for TCP and pass various configuration parameters to initialize this _MBX_SLAVE type slave object.
Parameters
- MBxSlave: Pointer to the slave object to be initialized.
- SlaveID: The slave ID to be configured for this slave object, in the range of 1 to 247.
- MAP: A pointer to a list ending with the MBX_MAP_LIST_END macro, defining all possible addresses.
- MBxSend: A function pointer for the data sending port.
- MBxGetc: A function pointer for the data receiving port.
- RxBuffer: Pointer to a memory space for storing received data.
- RxBufferSize: Total length of the memory space for storing received data. This memory space determines the maximum length of a single request that can be parsed.
- TxBuffer: Pointer to a memory space for storing data to be sent.
- TxBufferSize: Total length of the memory space for storing data to be sent. This memory space determines the maximum length of a single response that can be sent.
Return Value
- MBX_API_RETURN_DEFAULT(0x00): Normal return.
- MBX_API_RETURN_MAP_UNFORMAT(0x101): The provided MAP table is not properly formatted.
