How to read or write values from PM864 to PM583-ETH controller over Ethernet
Please give me some solution to get values from PM864 to PM583-ETH over Ethernet.

Directly it is not possible. I can advise 2 possible ways - that is simple explanation:
1. Serial Modbus RTU - COM3 from PM864 if it is not redundant with RS232/RS485 converter (or CI853 if AC800M is redundant +RS232/RS485) and COM1 port on PM583. In non redundant AC800M and AC500 you don't need any additional HW for the PLC's in this case.
2. Modbus TCP/IP (it is Ethernet based) - CI867 for AC800M and ETH port on PM583 - both configured for Modbus TCP/IP
