1.1.2 Precautions on Using This Function

As an SD memory card is used for the logging function, there are risks of loss of data or data
damage depending on usage conditions. Consider possible risks, design a system and make
an evaluation of the system before using the function.

■

Precautions when powering off the PLC

If the PLC is powered off during logging or accessing an SD memory card, the following
problems may occur.

● Data accumulated in the buffer memory are lost.

● Files may be damaged.

● The SD memory card may be damaged.

Take necessary measures such as the use of an uninterruptible power system (UPS) as
necessary.

■

Logging speed and writing speed into an SD memory card

When the speed accumulating data is faster than the writing speed into an SD memory card,
data cannot be saved. Make an evaluation thoroughly before use.

1.1.3 Selection of SD Memory Cards

For the Control Units with the Ethernet function (AFP0HC32ET/AFP0HC32EP), SD memory
cards can be used for copying projects and logging/trace applications. Note the following points
when selecting and using SD memory cards

■

Usable SD memory cards

Please use Panasonic SD memory cards for industrial use.

https://panasonic.net/cns/sdcard/industrial_sd/index.html

Cautions on handling an SD memory card

Usable SD memory cards

Card type Capacity

SD memory card 2GB

SDHC memory card 4GB to 32GB

The data saved in the SD memory card may be lost in the following cases. We assume no
responsibility whatsoever for the loss of saved data.

● The user or a third party has misused the SD memory card.

● When the SD memory card was affected by any static electricity or electrical noise.

● The SD memory card was taken out, or the PLC body was powered off, while the card was
being accessed.

■

Formatting an SD memory card

In principle, SD memory cards have been formatted by the time of purchase, and no formatting
by the user is required. If formatting becomes necessary, download formatting software for SD
memory cards on the following website.

"Our website (Japanese only)"

https://panasonic.jp/support/sd_w/download/index.html

"SD Association’s website"

https://www.sdcard.org/

● A file system formatted by PC's standard formatting software does not satisfy the SD
memory card specifications. Please use the dedicated formatting software.

● It is recommended to save important data in another media for backup.

● Never remove the card or power off the PLC while accessing the card. Data may be
damaged.

● Do not use an SD memory card the memory capacity of which is more than the usable
capacity. Data in the card may be damaged.

When the set conditions (bit device ON, cycle, time, and instruction) are met, the values of
operation devices will be saved in the logging buffer memory (RAM). The logging operation
continues until the file determination condition is met. Writing data to an SD memory card from
the logging buffer memory is automatically performed by PLC. It is not possible to perform this
operation by users.

3.1 Start and Stop of Logging/Trace Operation

3.1.2 Start and Stop by Instructions

■

Overview

● The logging/trace operation can be started and stopped by user programs for each logging/
trace number.

● Specify a logging/trace number (0 to 3) using the dedicated instruction, and execute with
arbitrary conditions.

● It takes a few milliseconds to a few seconds to start or stop the logging/trace operation.

● For stopping the logging/trace operation with instructions, request the stop after confirming
that the execution active flag (R9180/R9190/R9200/R9210) turns on. If requesting to stop
LOG n during the start operation, the operation error flag (R9007/R9008) or the logging/trace
error flag (R9185/R91915/R9205/R9215) turns on.

● For starting the logging/trace operation with instructions, request the start after confirming
that the logging/trace completed flag (R9182/R9192/R9202/R9212) turns on. If requesting to
stop LOG n during the start operation, the operation error flag (R9007/R9008) or the logging/
trace error flag (R9185/R9195/R9205/R9215) turns on.

● There is no problem if a start request is made for LOG n that is activated or during the
startup operation.

● There is no problem if a stop request is made for LOG n that is stopped or during the stop
operation.

3.1.3 Automatic Start by Setting

● When "Autostart" has been selected in the "LOG file settings" dialog box, the start request of
the logging/trace operation is made immediately after the mode is switched to RUN mode.

● The trace operation stops when the trace stop condition (bit device ON or buffer full) is
met. If the operation is forcibly stopped with the tool software or instruction while the trace
stop condition has not been satisfied, the trace operation is canceled and the data is not
saved.

3.2.4 Checking Logging Speed (When Selecting Logging For Application)

● When the logging speed to the buffer memory of the control unit is faster than the writing
speed into an SD memory card, the logging over-speed relay turns on. The logging over­speed relay turns on at the timing of logging trigger, and turns off if the speed does not
exceed at the end of scan.

● If overspeed occurs frequently, the buffer memory will be full and data cannot be
accumulated.

● Once the buffer memory is full, the buffer overflow flag turns on, and the buffer overflow
counter is incremented by one.

● If the buffer overflow occurs continuously, revise the logging conditions to decrease the
logging speed.

● To know how much logging data was lost at the time of buffer overflow, register the buffer
overflow counter as logging data.

● Even if the buffer overflow occurs, recording data into an SD memory card goes on, and
logging continues when free space becomes available in the buffer.

3.2 Operation Check Using Logging/Trace Monitor

● The free space of buffer memory can be checked with the system data registers DT90600 to
DT90603.

● The system relays (R9184/R9194/R9204/R9214) give a warning when the buffer memory of
each LOG number is full.

4.1 Flow of Logging Operation

■

Flow of Logging Operation

Step (1) Startup of logging operation

● The logging operation is started by any of the following methods; Tool software operation,
Instruction in a user program, and Autostart setting.

Step (2)-a: Data logging into logging buffer memory (RAM)

● After the startup of logging operation, logging data is executed with a specified condition
once the specified trigger condition (bit device ON, cycle, or time) is met.

● Logged data is stored once in the logging buffer memory (RAM) of the control unit.

Step (2)-b: Data transfer to SD memory card from logging buffer memory (RAM)

● Data is stored in the logging buffer memory (RAM) sequentially, and automatically written to
a file in an SD memory card by the control unit. It cannot be controlled by user programs.

● A LOG folder is created in an SD memory card for the LOG number that a file name is set.

● A file "specified file name (------current------).csv" for saving logging data is created in the
LOG folder.

● After that, the control unit continues saving data into the same file until the file determination
condition is met.

Step (3): Determination of file

● The file is determined when the specified file determination condition (bit device ON, time,
record limit) is met.

● The file determination is to rename the file "specified file name (------current------).csv"
created in step (2) after writing all the data stored in the buffer into the SD memory card.

● The time data of the oldest record is added to the specified file name.
Example) When the file name is Sample, and the oldest record was recorded in 12 o'clock on

April 1, 2013, it is saved as "specified file name (130401_120000).csv".

● Once the file is determined, a new file "specified file name (------current------).csv" for saving
the next logged data is created. The logging operation restarts when the logging trigger
condition is met.

Step (4): Stop of logging operation

● The logging operation is stopped by either of instruction in user programs or tool software
operation.

● Once the logging operation stop is requested, all the data in the buffer memory in the control
unit is written into the file in the SD memory card and determined. While the logging
operation is continuing, the records logged so far are saved and the file is determined even if
the specified file determination condition has not been satisfied.

● The time data of the oldest record is added to the specified file name.

● When the logging trigger setting is "Bit", "Cycle" or "Time", data is stored in the buffer memory
at the end of the scan time. In the case of Instruction, it is stored when the F422 LOGSMPL
instruction is executed.

WUME-FP0HLOG-03 4-3

4.2 Operation When Logging is Selected for Application

4.2 Operation When Logging is Selected for Application

4.2.1 Operation When Logging Operation is Started

The following operations are executed when the start operation is requested.

● Registered data is confirmed.

● Once the logging/trace becomes executable, the logging/trace execution active flag (R9180/
R9190/R9200/R9210) turns on. When the logging trigger condition is met under this
condition, the logging/trace operation starts.

● All logging/trace control relays other than the logging/trace execution active flags for LOG n
(R9180/R9190/R9200/R9210) are cleared once during the start request operation.

● Once writing data into an SD memory card becomes enabled after the logging/trace
execution active flag (R9180/R9190/R9200/R9210) turned on, the SD card buffer logging/file
writing active flag (R9181/R9191/R9201/R9211) turns on.

● When an SD memory card that can be normally read and written is not inserted, or the
battery cover is open, an operation error occurs.

4.2.2 Operation When Logging Operation Stops

■

Operation when switching from RUN mode to PROG. mode

● All logging operations stop.

● All information saved in the buffer memory of the control unit is written into a file, and the file
is determined.

4.2.3 Operation When Power Supply Turns Off

■

Operation When Power Supply Turns Off

● When activating the logging/trace function, the power off flag during SD memory card access
(R917F) turns on.

● The data stored in the logging buffer of the control unit will be discarded.

● In case of the middle of file writing, written data or files may be damaged, or the SD
memory itself may not be read.

4.2.4 Operation When the Battery Cover of Control Unit is Open

The following operations are performed when the battery cover is open during the logging
operation.

4-4 WUME-FP0HLOG-03

4.2 Operation When Logging is Selected for Application

■

Operation of system relays

● The logging/trace execution active flag and the SD card logging execution active flag
(R9180/R9190/R9200/R9210) stays on while the battery cover is open.

● The logging/trace execution active flag (R9180/R9190/R9200/R9210) turns off when the
condition to stop the logging operation is met. The SD card buffer logging/file writing active
flag (R9181/R91919/R9201/R9211) is kept in the on state.

● The logging operation into the logging buffer (RAM) continues even when no SD memory
card is inserted. Once the logging buffer (RAM) becomes full, the buffer overflow flag turns
on.

● When the battery cover is closed, the SD card buffer logging/file writing active flag (R9181/
R91919/R9201/R9211) also turns off.

■

File status in SD memory card

● The file "specified file name (------current------).csv" in which logging data was saved before
opening the cover is held in the SD memory card.

● Once the battery cover is closed, saving data into files starts again.

4.2.5 Operation When the Number of Determination Files Reaches the Maximum Number of Generations

■

Operation when the number of determination files reaches the maximum number
of generations

● The operation when the number of determination files reaches the maximum number of
generations varies depending on the log file settings.

4.3 System Management Information Relating to Logging Function

4.3.1 System Management Information and Operation

● Files are managed in the PLC as follows. The PLC performs operations based on the stored
management information even if an SD memory card is removed during logging, and another
SD memory card in different conditions from the conditions managed in the PLC is inserted.

● Writing data into an undetermined file "specified file name (------current------).csv" is executed
every time specified records are stored. The number of written records can be confirmed in
the special data registers (DT90640 to DT90643).

● The number of determined files (generations) of determined files is managed during the
logging operation. The number of determined files can be confirmed in the special data
registers (DT90660 to DT90663).

● When the file is determined, the determined date is managed in the internal memory. The
time data of the oldest file is stored in the special data registers (DT90680 to DT90687). The
clock data is the number of seconds accumulated from 00:00:00 on January 1, 2001.

4.3.2 Clearing Management Information

■

Clearing management information

Log file management information of the PLC is cleared in the following cases.

● When LOG n settings are deleted or all log settings are initialized from the tool software
FPWIN GR7

● When a buffer allocation different from stored data is downloaded, all log settings are
initialized.

● When a LOG n definition different from stored data is downloaded, only the different LOG n
is cleared.

● If the above clearing operation is performed, log file management information is initialized, and
files remained in the SD memory card are regarded as non-existent. Delete files beforehand,
and use it.

● When restarting logging with the same condition without changing the settings, the operation
continues with the previous system information, the number of generations and the oldest time
data of the file. After restarting logging, the number of generations is added to the data before
the restart, and the existing value is held for the oldest time data.

Flow of Trace Operation

Step (1) Startup of trace operation

● The trace operation is started by any of the following methods; Tool software operation,
Instruction in a user program, and Autostart setting.

Step (2): Data logging

5-2 WUME-FP0HLOG-03

5.1 Flow of Trace Operation

● After the startup of the trace operation,tracing data is executed with a specified condition
when the specified trigger condition (bit device ON, cycle, or instruction) is met.

● Traced data is stored in the logging buffer memory (RAM) in the control unit.

● After that, the trace operation continues until the trace stop condition is met.

Step (3): Stop of trace operation

● The trace operation stops when either condition is met, bit or buffer full.

● When the trace stop condition is bit, the trace operation stops after the logging performed for
the specified number of samplings after the condition was met.

● When the trace stop condition is buffer full, the trace operation stops immediately.

● When the trace operation is complete successfully, the trace data acquisition done flag
(R9189/R9199/R9209/R9219) turns on. At that time, a time chart can be displayed on the
programming tool FPWIN GR7 by reading the logged data.

● When "Write file after completion of trace" is set, all the data in the buffer memory in the
control unit is written into the file in the SD memory card and determined. The time stamp
information is the time data at the time of the occurrence of stop trigger.

● In the data logging process into the buffer memory, when Bit or Cycle has been specified, the
bit or the cycle is checked at the end of scan, and data is stored in the buffer memory when the
condition is met. When Instruction has been set, data is stored into the buffer memory when the
instruction is executed.

● If the trace operation is stopped by the tool software operation or the F421 (LOGED) instruction
while the trace stop condition has not been met, logged data is not saved in either the buffer
memory (RAM) or an SD memory card.

are operated for trace application), only one LOG can be displayed on the time chart.

● A maximum of 128 devices can be registered for one LOG, however, there are restrictions on
devices to be graphically displayed on the time chart.

• For contacts: Depends on the resolution of a used display

• For data: Up to 6 devices

● Time cannot be measured with the cursors (C, R) on graphs when the LOG displayed as a

6.1 Operations When Errors Occur

6.1 Operations When Errors Occur

6.1.1 Operation When Power Supply Turns Off

■

Operation When Power Supply Turns Off

● While the logging/trace buffer logging/file writing is performed (R9179 is on), the power off
flag during SD memory card access flag (R917F) turns on.

● The data stored in the buffer of the control unit will be discarded.

● In case of the middle of file writing, written data or files may be damaged, or the SD
memory itself may not be read.

6.1.2 Operation When Errors Occur (Only When Selecting Logging for Application)

■

Operations when determined files with the same time data are created

State Operation

Create an error file with the following file name, and exclude them from the

When multiple data are logged in
one second

When time data was turned back

target for generation management.

File name (Date_Time_ERR).csv

If the same file is created, discard the current file and continue the logging
operation.

If detecting that time is turned back from the previous record in logging
operation, it is regarded as a file determination trigger, and a file with the
following file name is created and excluded from the target for generation
management.

File name (Date_Time_TIM).csv

The logging operation continues.

■

Operations when reactivating the power supply

State Operation

When a current file with 0 record
exists

When a current file with N records
exists

■

Operation when log data is zero and file determination is requested

Newly create a current file based on the file definition.

Newly create a current file based on the file definition after determining the
current file.

The determined file name is “file name (date_time_POW).csv, and it is
excluded from the target for generation management.

The request for file determination is ignored.

■

Operation when the F422(LOGSMPL) instructions in main program and interrupt
program are executed simultaneously

The F422(LOGSMPL) instruction in the interrupt program is not executed.

6.1 Operations When Errors Occur

6.1.3 Operations When Inserting/Removing SD Memory Card During Logging/ Trace

■

Operations when inserting/removing an SD memory card

● If the cover is opened during the execution of logging/trace, all open files are closed and
access stops after the completion of active file access.

● Once the access stops, the SD memory card access LED turns off, and the SD memory card
can be removed.

● As the logging into the buffer memory in the control unit continues even after removing the
SD memory card, pay attention to buffer overflow.

● A file in the middle of logging when the cover was opened is saved as "specified file name
(------current------).csv". Once the SD memory card is inserted again, writing into the file in the
SD memory card restarts adding data to the "specified file name (------current------).csv".

7.1 Operation of Sampling Trace Function

7.1 Operation of Sampling Trace Function

■

What is Sampling Trace Function?

● Using the sampling trace function enables the PLC to take samples, record and accumulate
the state of arbitrary data of 16 bits + 3 data registered in the PLC, and to examine the
changes in the bit and data in details after stopping sampling at an arbitrary timing.

● The sampling trace function is used in the time chart monitor function under the online menu
of FPWIN GR7.

● The logging/trace function and sampling trace function cannot be used simultaneously. Either
one of them can be used.

■

Types of sampling timing (When an instruction is executed, or at regular time
intervals)

1. Sampling at regular time interval, from 10 ms

2. Sampling by F155(SMPL) instruction

● Sampling for every scan can be executed by the instruction. Also, more than one samplings
can be executed in one scan.

● Timing for the execution of the F155 (SMPL) instruction can be set by the ladder sequence.

● It is not possible to activate the sampling at regular time intervals and the sampling by the
F155(SMPL) instruction simultaneously.

■

How to stop sampling

Methods of the stop trigger (request): Following two methods are available.

1. Deactivate request by the tool software

2. Deactivate request by F156(STRG) instruction

● If the stop trigger activates, the PLC will continue to take samplings for the specified No. of
delay, and then stop the sampling operation.

● Once the sampling operation stops, the data will be automatically retrieved by the tool
software and will be indicated in a time chart.

● The number of samples before and after the trigger point can be adjusted by the number of
delay. For the initial settings (number of samples: 1000, number of delay: 100), the number
of samples before and after the trigger point is 900 and 100 respectively.
