*1 : Relayed stations cannot be accessed via Q motion CPU.
*2 : Since CC-Link IE Field Network is not supported, Q12DCCPU-V (Basic mode), QSCPU, and Q motion CPU relayed by
CC-Link IE Field Network cannot be accessed.
*3 : Since CC-Link IE Controller Network is not supported, LCPU relayed by CC-Link IE Controller Network cannot be accessed.
*4 : Since the communication paths are not supported, this module cannot be accessed.
