[LINK]: Q series PLC link system

[potetojb]

Hi all.

i have 1 project to link 3 Q series plc together.

1st plc is the master and PLC 2 & 3 slave.

---- 1 ) only 20 I/O(x20-x39, y20-y39) and 10 Data memory (DM 0-9 ) willbe link to PLC 1st form PLC 2. ( 15m to PLC1)
---- 2 ) only 30 I/O(x20-x49, y20-y49) and 20 Data memory (DM 0-19 ) willbe link to PLC 1st form PLC 3. (25m to PLC1)

-- IF plc 1 down. PLC 2& 3 still can run but detect error (master down)
-- IF plc 2 or 3 down. PLC 1 and (2 or 3) still can run but detect error (slave down)

What is the best and easy way to link this system.

Using cc-link. rs485 and melsecnet/h ( to Expensive). or have other way
