5 HANDLING CC-LINK EMBEDDED I/O ADAPTER
5.2 Cascading Method
The CC-Link embedded I/O adapters can be cascaded. Up to two adapters can be
installed side by side in the same board.
Cascade the adapters as shown below.
The following diagram gives an example of 16-point CC-Link embedded I/O adapters.
Review the pin numbers when 32-point CC-Link embedded I/O adapters are used.

POINT
Since the cascade communication pattern is easily affected by noise, it must be
separated as far away as possible from the other noise-laden patterns (power
supply, I/O signals).
