A
Appendix 3 CPU Module Processing Time
Appendix 3.3 Factors that increase the scan time
(b) Online change (files)
When a file is written to the running CPU module, the processing time listed in the following table is required.
*1
*1 The time in the table is for the case where the service processing count is set to one.
(8) Non-group output status read
In multiple CPU systems, the scan time increases when "All CPUs Can Read All Outputs" is selected in the
Multiple CPU settings screen of the PLC parameter dialog box.
