The auto-tuning function will automatically set the important constants, such as the proportional gain and the integral time, to ensure optimum PID control. There are two auto-tuning methods: limit cycle method and step response method. Limit Cycle Method For acquiring satisfactory control results in PID control, it is necessary to obtain the optimal value of each constant (parameter) suitable to the control target.

Page 105: Chapter 11 Constant Scan
CONSTANT SCAN Since the processing time differs as per the execution/non-execution of command used in the program, the scan timer changes with every scan. By setting the constant scan, because a program can be repeatedly executed while keeping scan time at a specified amount of time, even when the execution time of the program changes, the I/O refresh interval can be constant.
Page 106 Conditions of setting time Set a value that meets the following relational equation for the setting time of the constant scan. "WDT setting time" > "Constant scan setting time" > "Maximum scan time of the program" When the maximum scan time of the program is longer than the setting time of the constant scan, it results in error. The constant scan time is ignored and it is executed with the scan time of the program.

When trigger instruction executed A trigger occurs when the LOGTRG instruction is executed. (MELSEC iQ-F FX5 Programming Manual (Instructions, Standard Functions/Function Blocks)) 19.5 States of the Data Logging Function The data logging function has various states that can be classified into data logging and storage.
Page 138: Storage States
Storage states The following table lists all the possible storage states. Storage states Description Unsaved Has not yet stored the collected data into the SD memory card. Saving in progress Has begun but not yet finished storing the collected data into the SD memory card. Save completed Has finished storing the collected data as much as the specified number of records into the SD memory card.
Page 139: Switching To A Storage File
Switching to a storage file The data collected by data logging is temporarily stored in a stack file that resides in the SD memory card. The stack file can be switched to a storage file to free the space in the SD memory card. How file switching (log rotation) works File switching works as follows: The CPU module writes collected data into a stack file (such as LOG01.BIN).
Page 140 Storage file The CPU module creates a subfolder ("storage file container folder") under the file storage folder and writes storage files to that storage file container folder. One storage file container folder can contain up to 256 storage files. When the files contained in the current storage file container folder reach the maximum number, the CPU module creates a new storage file container folder at the time of next storage file switching and begins writing storage files to that new folder.
Page 141: Internal Buffer
19.7 Internal Buffer The internal buffer is a system area used to temporarily store collected data. Internal buffer capacity setting This setting can be specified using an engineering tool (Page 115 INTERNAL BUFFER CAPACITY SETTING). For trigger logging, increasing the internal buffer capacity allows for a larger number of data records collected before a trigger and also helps to prevent processing overflow.
Page 142: Missing Data
19.9 Missing Data The term "missing data" means that some of the collected data is missing, resulting in data discontinuity. Conditions under which missing data occurs Missing data occurs under the following conditions: Item Description Processing overflow • When the internal buffer responsible for tentatively storing the logged data is unable to store new logged data because the SD memory card does not store data •...

Setting the operation at the time of transition to RUN This function configures the operation of data logging that occurs when the user performs the following operations (transition to RUN) after the data logging setting are registered.
Page 144 Operation during SD memory card replacement Mounting the replaced SD memory card on the CPU module causes a "LOGGING" folder to be created. When becoming ready for running the logging function, the CPU module resumes the data transfer into the SD memory card. The CPU module operates differently as follows depending on the folder configuration in the replaced SD memory card.
Page 145: Data Logging Execution By Special Relay
Data logging execution by special relay The data logging setting can be registered by the special relay and be executed on the data logging setting file stored in the SD memory card.

Page 148 Stopping/suspending data logging After data logging is stopped or suspended from within the CPU Module Logging Configuration Tool or special relay, all the data in the internal buffer is written into the target memory. If a small number of records or a small file size is specified as part of the storage file switching condition, writes to the target memory may take a longer time.
Page 149 Access to the SD memory card If data logging is performed with a small setting of the data collection interval/timing or with a large number of records to be collected, access (read/write) to the SD memory card occurs so frequently that a delay occurs in completing the access. To avoid such a delay, use the following workarounds: •...

The error code can be checked in either of the following ways. • Module diagnostics of engineering tool (MELSEC iQ-F FX5 User's Manual (Startup)) • Special register (SD0 (latest self-diagnostics error code), SD10 to SD25 (self-diagnostics error code)) (Page 348 Special Register List) This section describes errors that may occur in the CPU module and actions to be taken for the errors.
Page 403: Operation When An Error Occurs
Operation when an error occurs There are two types of errors: continuation errors and stop errors. Stop error If a stop error occurs, the CPU module stops its operation and the operating state will be in STOP. Modules can communicate with the CPU module even after a stop error occurs in the CPU module.
