Here, use of the QD62 (E/D) with the Q12PRH/Q25PRHCPU is explained.
(1) GX Configurator-CT
When using GX Developer to access the Q12PRH/Q25PRHCPU through the
intelligent function module on the extension base unit, GX Configurator-CT
cannot be used.

Here, use of the QD62 (E/D) on the MELSECNET/H remote I/O station is explained.
(1) Number of QD62 (E/D) that can be installed when the remote I/O
station is used
See Section 2.1 concerning the number of QD62 (E/D) that can be installed
when the remote I/O station is used.
(2) Limitations when using the remote I/O station
(a) The coincidence detection interrupt function cannot be used.
(b) When the QD62 (E/D) is used on the MELSECNET/H remote I/O station, a
delay will occur due to the link scan time. Therefore, fully verify that there will
be no problem with controllability in the target system.
Example) When processing is executed using the counter value input by a
sequence program, variations will occur due to a delay in the link
scan time.
