FP_SD_WRITE_DUT

This DUT can be used with the following instruction(s): FP_SD_WRITE

Elements of the DUT (identifiers):

wFormat

Writing format

0: –

1: UINT, 5 digits, CSV

2: INT, 6 digits, CSV

3: UDINT, 10 digits, CSV

4: DINT, 11 digits, CSV

5: REAL, 13 digits, CSV

6: –

7: WORD, 4 digits, CSV

8: DWORD, 8 digits, CSV

9: –

10: Character string, CSV

11: Binary data, BIN

wMode

Writing mode

0: New file mode. Deletes the file contents, and then writes the data. When no file exists, it creates a new file. Data is always written from the head of file.

1: Append to file mode. Appends additional data to the end of a file. When no file exists, it creates a new file. Data is always written form the end of file.

2: Pointer mode 1. Data are written from head of file starting at the pointer specified by udiBytePosition.

3: Pointer mode 2. Data are written from the end of file starting at the pointer specified by udiBytePosition.

wOption (must be set before executing FP_SD_WRITE)

Option (only valid for CSV data)

Bit 0–7: New lines

• 0: No new lines inserted, only at the end of the file.

• 1–255: New lines are inserted every n^th delimiter, e.g. for bit 0–7=3, a new line is inserted every third delimiter.

Bit 8: Postfix written at the end of the data

• 0: New line

• 1: Comma

Bit 9: Zero suppression

• 0: No zero suppression

• 1: Zero suppression is performed

Bit 10–15: Reserved for the system (0)

udiBytePosition (will be returned by FP_SD_WRITE)

Pointer position [bytes]

Only available for pointer mode 1 (wMode=2) or 2 (wMode=3).After writing, the pointer moves to the position where writing has been completed. The next writing operation will start from this point.

udiNumberOfDataWritten (will be returned by FP_SD_WRITE)

Number of written data

• For wFormat=1–8: Number of 16-bit/32-bit comma-separated data

• For wFormat=10: Number of 8-bit characters

• For wFormat=11: Number of 16-bit data
