modbus_read_input_bits()			      modbus_read_input_bits()

Name
       modbus_read_input_bits -	read many input	bits

Synopsis
       int modbus_read_input_bits(modbus_t *ctx, int addr, int nb, uint8_t *dest);

Description
       The  modbus_read_input_bits() function shall read the content of	the nb
       input bits to the address addr of the  remote  device.  The  result  of
       reading	is stored in dest array	as unsigned bytes (8 bits) set to TRUE
       or FALSE.

       You must	take care to allocate enough memory to store  the  results  in
       dest (at	least nb * sizeof(uint8_t)).

       The function uses the Modbus function code 0x02 (read input status).

Return value
       The  function  shall return the number of read input status if success-
       ful. Otherwise it shall return -1 and set errno.

Errors
       • EMBMDATA, too many discrete inputs requested
