2.5 About Use of the QD70 on the MELSECNET/H Remote I/O Station

Here, use of the QD70 on the MELSECNET/H remote I/O station is explained.

(1) Number of QD70 that can be installed when the remote I/O station

is used

See Section 2.3 concerning the number of QD70 that can be installed when the

remote I/O station is used.

(2) Limitations when using the remote I/O station

When the QD70 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) Depending on the ON time of the positioning completed signal, the ON

status may not be detected due to a delay in the link scan time.
