Appendix 2 CPU Module Processing Time
Appendix 2.2 Factors that Increase the Scan Time
(7) Time taken to collect module errors
Use the following formula to calculate the increase in scan time when the module error collection function is used.
[Increase in the scan time]
KM1 + (N1 × KM2) + (N2 × KM3) [µs]
• N1: FNumber of errors collected per scan by the built-in CC-Link or external modules
• N2: FNumber of errors collected by the built-in I/O
(8) Data logging function
For the increase in scan time when using the data logging function, refer to the following.
MELSEC-L CPU Module User's Manual (Data Logging Function)
CPU module KM1 KM2 KM3
