PARAMETERS
* 1: When changing the device points, the refresh ranges of the network modules and the auto refresh
ranges of the intelligent function modules must be set so as not to be out of the out of the
corresponding device points.
If the device points are set exceeding the corresponding device range, the data may be written
into other devices or an error may occur.
* 2: For the Universal model QCPU, the latch clear cannot be made by the switch operation.
* 3: Setting in the range is allowed for the Universal model QCPU.
* 4: For the Universal model QCPU, the scan time is prolonged when the device is latched. When
latching a device, consider the prolonging scan time. (
Section 10.1.2 (11))
* 5: In the Universal model QCPU whose serial number (first five digits) is "10042" or later, 0 point can
be set for step relays (S).
* 6: Setting is allowed only when the Universal model QCPU is used.
* 7: Setting is allowed only when the Universal model QCPU whose serial number (first five digits) is
"10042" or later.
