FUNCTIONS OF CONFIGURATION TOOL (MODULE SETTINGS)
POINT
(1) For the types of programmable controller CPUs, product information, and
system configurations of high speed data sampling, refer to the following
section.
 Section 7.2.1 (1) System configurations compatible with high speed
data sampling
(2) For devices which can be specified during high speed data sampling, refer to
the following section.
 Section 3.2 (3) Accessible devices
(3) The total number of data logging, event logging, and report settings in which
high speed data sampling is set, is a maximum of 32 settings.
(4) When high speed data sampling is specified, there is an effect on the
sequence scan time because of the data transfer from the programmable
controller CPU to the high speed data logger module.
The sequence scan time delay can be adjusted with the high speed data
sampling setting.
For the effect on the sequence scan time, refer to the following sections.
 Section 17.3 Effect on Sequence Scanning Time
 Section 11.4.8 High speed data sampling setting
(5) Since general data sampling is not synchronized with the control CPU's
sequence scan, data separation may occur.
 Section 3.2 (5) Access units
To perform data sampling synchronized to the sequence scan, use high
speed data sampling.
