Refer to the "Transition from MELSEC-A/QnA (Large Type), AnS/QnAS (Small Type) Series to Q Series Handbook
(Network Modules)" for guidance on exchanging the MELSECNET system to the MELSECNET/H system.
Additionally, use caution on the following points when configuring the MELSECNET/H network system on the Q00UCPU.
(1) The Q00UJCPU, Q00UCPU, and Q01UCPU can only load one network module.
To load two or more network modules, use the Universal model QCPU other than the Q00UJCPU, Q00UCPU, or
Q01UCPU.
(2) The Q00UJCPU, Q00UCPU, and Q01UCPU have functions and abilities that are not compatible with the
MELSECNET/H network (PLC to PLC network).
Refer to Section 2.2.3 of Q Corresponding MELSECNET/H Network System Reference Manual (PLC to PLC Network)
