The code does however combine the check for - inter character time out and frame time out by incorporating a maximum - time out allowable when reading from the message stream. - - These library of functions are designed to enable a program send and - receive data from a device that communicates using the Modbus protocol. - - SimpleModbusSlave implements an unsigned int return value on a call to modbus_update(). - This value is the total error count since the slave started. It's useful for fault finding. - - This code is for a Modbus slave implementing functions 3 and 16 - function 3: Reads the binary contents of holding registers (4X references) - function 16: Presets values into a sequence of holding registers (4X references) - - All the functions share the same register array. - - Exception responses: - 1 ILLEGAL FUNCTION - 2 ILLEGAL DATA ADDRESS - 3 ILLEGAL DATA VALUE - - Note: - The Arduino serial ring buffer is 128 bytes or 64 registers. - Most of the time you will connect the arduino to a master via serial - using a MAX485 or similar. - - In a function 3 request the master will attempt to read from your - slave and since 5 bytes is already used for ID, FUNCTION, NO OF BYTES - and two BYTES CRC the master can only request 122 bytes or 61 registers. - - In a function 16 request the master will attempt to write to your - slave and since a 9 bytes is already used for ID, FUNCTION, ADDRESS, - NO OF REGISTERS, NO OF BYTES and two BYTES CRC the master can only write - 118 bytes or 59 registers. - - Using the FTDI converter ic the maximum bytes you can send is limited - to its internal buffer which is 60 bytes or 30 unsigned int registers. - - Thus: - - In a function 3 request the master will attempt to read from your - slave and since 5 bytes is already used for ID, FUNCTION, NO OF BYTES - and two BYTES CRC the master can only request 54 bytes or 27 registers. - - In a function 16 request the master will attempt to write to your - slave and since a 9 bytes is already used for ID, FUNCTION, ADDRESS, - NO OF REGISTERS, NO OF BYTES and two BYTES CRC the master can only write - 50 bytes or 25 registers. - - Since it is assumed that you will mostly use the Arduino to connect to a - master without using a USB to Serial converter the internal buffer is set - the same as the Arduino Serial ring buffer which is 128 bytes. - - The functions included here have been derived from the - Modbus Specifications and Implementation Guides - - http://www.modbus.org/docs/Modbus_over_serial_line_V1_02.pdf - http://www.modbus.org/docs/Modbus_Application_Protocol_V1_1b.pdf - http://www.modbus.org/docs/PI_MBUS_300.pdf -*/ - -// function definitions - +typedef struct { + int RelaisK1; + int RelaisK2; + int temperatuur ; + int beweging ; +} dataModbus; const uint16_t crc_tab_8005_reflected[] = { @@ -120,12 +46,14 @@ }; void modbus_configure(long baud, int _slaveID ); -int modbus_read(void); -int modbus_read2(void); +void CRCChecking(void); +extern int modbus_read(dataModbus *allData); +int functionCodeCheckMaxData(int functionCode); +void TimerCheck(void); //unsigned short calculate_crc16_Modbus( uint8_t *checkArray , int dataLengt ); //unsigned long update_crc16_reflected(const long *table, unsigned long crc, unsigned int c ); //unsigned long update_crc16_A001( unsigned long crc, unsigned int c ); -int modbus_sendData(void); +int modbus_sendData(dataModbus *allData); uint16_t update_crc16_reflected(const uint16_t *table, uint16_t crc, unsigned int c ); uint16_t update_crc16_A001( long crc, unsigned int c );
