*1 This range is effective when collecting a large amount of data (such as logging and recipe function) on other than the monitor
screen.
However, the range may affect the sequence scan time when connecting to Q00UJ/Q00U/Q01U/Q02UCPU or Q00J/Q00/
Q01CPU.
If you want to avoid the influence on the sequence scan time, do not set [High(Normal)].
(This setting hardly affects QCPUs other than the above.)
*2 Set this range if you want to avoid the influence on the sequence scan time further than the [Middle] setting when connecting to
Q00UJ/Q00U/Q01U/Q02UCPU or Q00J/Q00/Q01CPU.
However, the monitor speed may be reduced.
*3 When using a global label, to read or write more than 235 two-byte characters, set the [Monitor speed] to [High (Standard)] or
[Middle].
If [Monitor speed] is set to [Low], a system error occurs when reading or writing.
