Appendix 3 CPU Module Processing Time

Appendix 3.3 Factors that increase the scan time

When executing any of the functions or operations described in this section, add the given processing time in this

section to the time value calculated in Page 469, Appendix 3.1.

(1) Sampling trace

When the sampling trace function ( Page 184, Section 3.14) is executed, the processing time listed in the

following table is required.

[Conditions] 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)

*1 When specifying devices in the trigger point setting, the scan time may be increased by up to 0.163µs per instruction.
