2.2.5 Delay Preset
This parameter sets an interval for each Data Map copy operation. The value you
put for the D
ELAY PRESET is not a fixed amount of time. It is the number of
firmware scans that must transpire between copy operations.
The firmware scan cycle can take a variable amount of time, depending on the
level of activity of the protocol drivers running on the ProLinx gateway and the
level of activity on the gateway’s communication ports. Each firmware scan can
take from 1 to several milliseconds to complete. Therefore, Data Map copy
operations cannot be expected to happen at regular intervals.
If multiple copy operations (several rows in the Data map section) happen too
frequently or all happen in the same update interval, they could delay the process
scan of the gateway protocols, which could result in slow data updates or missed
data on communication ports. To avoid these potential problems, you should set
the D
ELAY PRESET to different values for each row in the Data Map section and
set them to higher, rather than lower, numbers.
For example, D
ELAY PRESET values below 1000 could begin to cause a
noticeable delay in data updates through the communication ports. And you
should not set all D
ELAY PRESETS to the same value. Instead, use different
values for each row in the Data Map such as 1000, 1001, and 1002 or any other
different D
ELAY PRESET values you like. This will prevent the copies from
happening concurrently and prevent possible process scan delays.
