Process Control Function Processing Time - Mitsubishi Electric MELSEC iQ-R-R00CPU User Manual

Processing time of the CPU module database access (from external device) function
The table below lists the processing time under the following conditions:
Condition 1
• Number of records: 10000
• Number of fields: 16
The data type of the field is specified as WORD (6 fields), DOUBLE
PRECISION (6 fields), NLSCHAR(UNICODE) [124 characters] (3 fields),
and BOOLEAN (1 field).
• Main key: Provided
• Functions that require access to files in the SD memory card except for the
CPU module database access function are not active.
The following table lists the processing time until the database operation is completed with the CPU module database access
function.
Item
Connect to the database of the CPU module from the application (Microsoft Access).
Select a record in the database of the CPU module from the application (Excel). (SELECT)
Insert 1000 records in the database of the CPU module from the application (Microsoft Access). (INSERT)
Update a record in the database of the CPU module from the application (Microsoft Access). (UPDATE)
Delete a record in the database of the CPU module from the application (Microsoft Access). (DELETE)

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.
