8.7 Data logging
Programmable controller
System Manual, 04/2012, A5E02486680-06 327
The DataLogCreate DATA parameter points to a structure that specifies the number of data
fields and the data type of each data field for one data log record. The table above gives the
bytes required in the CSV file for each data type. Multiply the number of occurrences of a
given data type by the number of bytes it requires. Do this for each data type in the record
and sum the number of bytes to get the total size of the data record. Add one byte for the
end of line character.
Size of a data log record = summation of bytes required for all data fields + 1 (the end of line
character).
Calculate the memory requirement for an entire data log file
The RECORDS parameter of the DataLogCreate instruction sets the maximum number of
records in a data log file. When the data log file is created the maximum memory size is
allocated.
Size of data log file = (number of bytes in one record) x (number of records).
8.7.5 Data log example program
This Data log example program does not show all the program logic necessary to get sample
values from a dynamic process, but does show the key operations of the Data log
instructions. The structure and number of log files that you use depends on your process
control requirements.
Note
General usage of Data log files
 Data log files are automatically opened after the DataLogCreate and DataLogNew File
operations.
 Data log files are automatically closed after a PLC run to stop transition or a PLC power
cycle.
 A Data log file must be open before a DataLogWrite operation is possible.
 A maximum of eight data log files may be open at one time. More than eight data log files
may exist, but some of them must be closed so no more than eight are open. Example data log names, header text, and the MyData structure are created in a data block.

The three MyData variables temporarily store new sample values. The process sample
values at these DB locations are transferred to a data log file by executing the DataLogWrite
instruction. Network 4 The EN input state is based upon when the DataLogCreate operation is complete.
A create operation extends over many scan cycles and must be complete before executing a
write operation. The positive edge signal on the REQ input is the event that triggers an
enabled write operationNetwork 5 Close the data log once the last record has been written. After executing the
DataLogWrite operation that writes the last record, the log file full status is signaled when
DataLogWrite STATUS output = 1. Network 6 A positive signal edge DataLogOpen REQ input simulates the user pushing a
button on an HMI that opens a data log file. If you open a Data log file that has all records
filled with process data, then the next DataLogWrite operation will overwrite the oldest
record. You may want to preserve the old Data log and instead create a new data log, as
shown in network 7Network 7 The ID parameter is an IN/OUT type. First, you supply the ID value of the existing
Data log whose structure you want to copy. After the DataLogNewFile operation is complete,
a new and unique ID value for the new Data log is written back to the ID reference location.
The required DONE bit = TRUE capture is not shown, refer to networks 1, 2, and 4 for an
example of DONE bit logic. After one additional record is written to the
file above which is full, the sixth write
operation overwrites the oldest record one
with record six. Another write operation
will overwrite record two with record
seven and so on. Copies DB start values or part of the
values, from load memory to a target
DB in the work memory.
The content of load memory is not
changed during the copy process.
WRIT_DBL(
req:=_bool_in_,
srcblk:=_variant_in_,
busy=>_bool_out_,
dstblk=>_variant_out_);
Copies DB current values or part of the
values from work memory to a target
DB in load memory.
The content of work memory is not
changed during the copy process.
Table 8- 142 Data types for the parameters
Parameter and type Data type Description
REQ IN BOOL A high signal starts the operation, if BUSY = 0.
SRCBLK IN VARIANT READ_DBL: Pointer to the source data block in load memory
WRIT_DBL: Pointer to the source data block in work memory
RET_VAL OUT INT Execution condition code
