2.2 When Using the QD65PD2 with Redundant CPU
This section lists restrictions when using the QD65PD2 with redundant CPU.
(1) Restrictions
• The coincidence detection interrupt function and the periodic interrupt function cannot be used.
• The dedicated instruction cannot be used.
2.3 When Using the QD65PD2 at a MELSECNET/H Remote
I/O Station
This section describes the use of the QD65PD2 at a MELSECNET/H remote I/O station.
(1) Number of modules
For the number of modules that can be mounted, refer to Page 20, Section 2.1.
(2) Restrictions
• The coincidence detection interrupt function and the periodic interrupt function cannot be used.
• The dedicated instruction cannot be used.
• When the QD65PD2 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.
When processing is performed using the count value input by the sequence program, variations will occur
due to a delay in the link scan time.
