Appendix 3 Processing Time - Mitsubishi Electric MELSEC iQ-R Series User Manual

Appendix 3
This section shows the processing time of the recording function.
Sampling time
The following shows the processing time of a CPU module required to sample a device and label.
It is added to the END processing when selecting "Each Scan" or "Time Specification" for the sampling method and to the
program execution time when selecting "Trigger Instruction" (processing time for the DATATRG instruction). (Page 44
Sampling methods of devices and labels)
In addition, when selecting "Safety Cycle Time" for the sampling method, the processing time of a CPU module (sampling
time) is included in the safety cycle time. (Page 44 Sampling methods of devices and labels)
When an interrupt program is executed during the END processing, the execution time of the interrupt program is included in
the sampling time.
In addition, if the program execution time of a CPU module is shorter than the accumulating execution time of a recorder
module/camera recorder module, the accumulating execution time is also included in the sampling time.
Note that the time required for data sampling differs depending on the CPU module type, device number of a sampling target,
type, and memory of a module (buffer memory, link device).
The sampling time is calculated with the following formula:
Sampling time (s unit) = 25 + (1) + (2) + (3) + (4) + (5) + (6) + (7) + (8) + (9) + (10) + (11)
The following table shows the details of each variable in the calculation formula.
