10.1.3Factors that increase the scan time
When executing any of the functions or operations described in this section, add the given processing time to the time
value calculated in Section 10.1.2.
(1) Sampling trace
When the sampling trace function ( Section 6.14) is executed, the processing time shown in Table10.16 is
required.
(2) Use of local devices
When local devices are used, the processing time shown in Table10.17 is required.
"n" in the table indicates the number of programs to be executed.
*1: Indicates the processing time when 10K points of local devices are used.
Table10.16 Processing time (when 50 points of the internal relay (for bit device) and 50 points of the data register (for word
device) are set as sampling trace data)
