Data type
Description
Bool
A low to high (positive edge) signal starts the operation. (Default value: False)
DWord
Numeric identifier of a data log. Only used as an input for the DataLogClose
instruction. (Default value: 0)
Note: Symbolic name access for this parameter is not allowed.
Bool
The DONE bit is TRUE for one scan after the last request was completed with
no error.
Bool
0 - No operation in progress
1- Operation on progress
Bool
The ERROR bit is TRUE for one scan, after the last request was terminated
with an error. The error code value at the STATUS parameter is valid only
during the single scan where ERROR = TRUE.
Word
Execution condition code (Default value: 0)
Description
No error
Data log not open
Call with no REQ edge: BUSY = 0, DONE = 0
First call with REQ edge (working): BUSY = 1, DONE = 0
N
call (working): BUSY = 1, DONE = 0
th
Data log does not exist.
Description
Closes an open data log file. DataLogWrite operations to
a closed data log result in an error. No write operations
are allowed to this data log until another DataLogOpen
operation is performed.
A transition to STOP mode will close all open data log
files.
STEP 7 automatically creates the associated instance
DB when you insert the instruction.
