If I connected the RESET pin for W5500 from RPi3. always cannot findout the slaves.

Because the LINK-UP is slowly.

There are 2 slaves. 1-OMRON NX-ECC203 2-OMRON GX-MD1618

Did you try to increase EC_TIMEOUTRET3 in 'soem/ethercattype.h' and rebuild soem lib? Currently I set it to 200ms. So far I has tested with several drives like Maxon MAXPOS, Servotronix, Elmo Gold, Fastech Ezi,..

frankgp, I have updated driver file to add one more function:

int wiznet_hw_config(uint32_t spi_clkDiv, int startup_rst, uint32_t link_wait_us)

You now can control:

SPI clock (3 possible speeds include 31.25 MHz(default), 15.625 MHz and 7.8125 MHz
RESET at startup or NOT
waiting after RESET if enabled You can call this function any place just before calling "ec_init". For more details, read description in wiznet_drv.h file and in updated examples. Cheers
