Process Control Function Processing Time - Mitsubishi Electric MELSEC iQ-R Series User Manual

When the file format is binary file
■When a global device is specified
The following table lists the collection intervals at which data can be collected under the following conditions.
• Scan time = 1.5ms (up to 3ms)
• Internal buffer capacity setting = 128K bytes per setting (default setting)
• Collection setting = Time specification (data collection at time interval)
• Data setting = Data register (D) (Data-type: word-signed (decimal number type))
• Output setting = Day/time column (output format is default) and index column are outputted.
• Save setting = 10000 records, operation when the number of saved files exceeded: overwriting
• Functions that require access to files in the SD memory card except for the data logging function must be not active.
• For the parameters, use the default setting values.

Process control function processing time

The process control function processing time is the time required to process the control loop when the process control
function is executed. The following table lists the processing time of some control loop examples.
Loop type
Two-degree-of-freedom PID control
(S2PID)
PID control (SPID)
Monitor (SMON)
For the processing time of each process control instruction, refer to the following.
