UNINTENDED EQUIPMENT OPERATION Do not change the[Trend]WriteWatchTime parameter in the citect.ini file, except on the advice of Technical Support for this product. Failure to follow these instructions can result in death, serious injury, or equipment damage. |
There are two uses for this parameter. The trend write task writes out trend data to disk, and then sleeps for the time specified in this parameter (before writing the next trend file). This small delay stops the trend write task from using too much CPU time when it is writing out a large number of files. If this parameter is set to 0, no delay occurs and the trend data is written to disk as fast as possible.
In addition, this parameter is used to define how long a trend will sleep for after the parameter, BytesWrittenBeforeSleep, has determined how long data will be written to disk.
Allowable Values: 0 to 60000 (milliseconds)
Default Value: 40
