2.1 M+FileOperation_SaveLoggingCSV_W_R
Functional description
• When i_bEN (execution command) is turned on, this FB stores the logging data stored in the file register in CSV format in
the SD memory card attached to the CPU module sequentially from the specified address of the file register (ZR) specified
in i_udDataAddr (start address of the storage location of logging data).
Ex.
The following shows an example of file register and CSV file content.
(1) i_udDataAddr (start address of the storage location of logging data): K10000
(2) i_uCHNum (number of channels): K2
(3) i_udSavePoints (number of save points): K10000
• Logging data is stored in increments of 500 points. When K1300 is specified for i_udSavePoints (number of save points),
logging data of 500 points is stored in an SD memory card first. Sequentially, data from 501 points to 1000 points is stored
and data from 1001 points to 1300 points is stored.
• Store logging data of each channel sequentially into the file register. Store signed word logging data into the file register.
• For the format of CSV files that this FB creates, refer to CSV File Output Format. (Page 16 CSV File Output Format)

2 FILE OPERATION FB
2.1 M+FileOperation_SaveLoggingCSV_W_R
• When this FB creates a CSV file in an SD memory card, a file of the same name, if already exists in the SD memory card,
is replaced with the newly created file.
• If the set value of i_uCHNum (number of channels) is out of range, o_bErr (error completion) turns on and the processing of
the FB is interrupted. In addition, 0100H is stored in o_uErrId (error code). (Page 15 Error code)
• If the set value of i_udSavePoints (number of save points) is out of the range, o_bErr turns on and the processing of the FB
is interrupted. In addition, 0101H is stored in o_uErrId. (Page 15 Error code)
• If the character length of the set value of i_snAppendFileName (CSV file name) is out of range, o_bErr turns on and the
processing of the FB is interrupted. In addition, 0102H is stored in o_uErrId. (Page 15 Error code)
• If the number of points of logging data that is read from the file register exceeds the capacity of the file register (ZR), the
processing of the FB is interrupted. In addition, 0200H is stored in o_uErrId. (Page 15 Error code)
• If SM606 (SD memory card forced disable instruction) is on when the logging data is stored in a CSV file, the SP.FWRITE
instruction is not processed, resulting in the logging data not being stored. In such a case, o_bErr turns on and the
processing of the FB is interrupted. In addition, 0201H is stored in o_uErrId. (Page 15 Error code)
• A CPU error occurs in the following cases: when this FB has been executed with no SD memory card inserted into the CPU
module; when the inserted SD memory card has no sufficient free space; or when the number of files stored is exceeded.
For the capacity of SD memory cards and the number of files stored, refer to the following.
MELSEC iQ-R Module Configuration Manual
• In the event of a CPU error, if the CPU module is in a stop error state, o_bErr and o_uErrId are not updated. In the event of
a CPU error, if the CPU module is in a continuation error state, o_bErr turns on and the error code is stored in o_uErrId.
(Page 15 Error code)
• The operating status (continue or stop) of the CPU module at the time of the failure of access to the SD memory card can
be set with the parameter.
• If i_bEN (execution command) is turned off when o_bOK (normal completion) or o_bErr is off, o_bErr turns on in one scan.
In addition, 0206H is stored in o_uErrId in one scan. (Page 15 Error code)
• The SP.FWRITE instruction (type 1) is used in this FB. If an error occurs in the SP.FWRITE instruction, o_bErr turns on and
the processing of the FB is interrupted. In addition, the error code for the SP.FWRITE instruction is stored in o_uErrId. (

Restrictions and precautions
• This FB does not include the error recovery processing. Prepare the error recovery processing separately to suit the user's
system and the expected operation.
• The FB cannot be used in an interrupt program.
• Using the FB in a program that is to be executed only once, such as a subroutine program or a FOR-NEXT loop, has a
problem that i_bEN (execution command) can no longer be turned off and normal operation is not possible; Always use the
FB in a program that is capable of turning off the execution command.
• The FB requires the configuration of the ladder for every input label.
• To use more than one of this FB, create an interlock to avoid simultaneous execution.
• Change the memory/device setting of CPU parameter so that the memory capacity required to use this FB is secured. If the
memory/device setting is not changed, an error may occur on GX Works3.
• The SP.FWRITE instruction is used in this FB. If a value that cannot be used in the SP.FWRITE instruction is specified for
i_snAppendFileName (CSV file name), an operation error (3405H) may occur when the FB is executing. For details on the
SP.FWRITE instruction, refer to the following.
MELSEC iQ-R Programming Manual (CPU Module Instructions, Standard Functions/Function Blocks)
• Specify a string (ASCII code or Shift JIS code) for i_snAppendFileName. If anything other than string is specified for
i_snAppendFileName, a file may not be written.

0102H A character string with an out-of-range character length is set in
i_snAppendFileName (CSV file name).
Set a string with character length of 1 to 28.
0200H The file register address exceeds the capacity of the file register
(ZR).
Review and correct the settings according to the following
relational expression, and then execute the FB again.
(i_udDataAddr (start address of the storage location of logging
data) + (i_uCHNum (number of channels) i_udSavePoints
(number of save points)) - 1) Maximum assignment address of
the file register (ZR)
0201H An access to the SD memory card has failed because SM606 (SD
memory card forced disable instruction) is on. While logging data
is being saved, turning on SM606 results in the partially created
CSV file being saved in the SD memory card.
Turn off SM606 and check that SM607 (SD memory card forced
stop status flag) is turned off, then execute the FB again.
0202H Execution of this FB has been attempted without inserting an SD
memory card into the CPU module.
Insert an SD memory card for saving the target CSV files into the
CPU module, and then execute the FB again.
0203H An access to the SD memory card has failed because SM600
(Memory card available flag) is off.
Make the SD memory card an available state, and then execute
the FB again.
0204H The SD memory card is frequently accessed from programs in
addition to this FB, and a timeout has occurred.
Reduce the frequency of the access to the SD memory card.
0205H Because SM601 (Memory card protect flag) is on, data cannot be
written to the SD memory card.
Turn off the protect switch on the SD memory card, check that
SM601 is off, and execute the FB again.
0206H i_bEN (execution command) has been turned off during the
processing.
Do not turn off i_bEN until o_bOK (normal completion) or o_bErr
(error completion) turns on.
Other than above Error codes related to the SP.FWRITE instruction executed when
logging data is written to an SD memory card.
For details on the error code that has occurred, refer to the
description of the SP.FWRITE instruction.
