Hi @sarikaautomations ,

Thanks for your interest in NXP MIMXRT series!

1. A: It's recommend using J56A/J56B (RGMII ports for ETH0/ETH2) for TCP/IP/Modbus communication. Using J57A (ECAT0 port) is not advised.

B: No. The RT1180 integrates ESC, not an ECAT master.

2. Yes, this is supported.

For more detailed information, please refer to this guide: UM12450: FRDM-IMXRT1186 Board User Manual

Best regards,
Gavin
