Poll After Set |

|
Description |
Determines if polling should be done after a setpoint. Valid values are: |
|
|
|
0 |
Do not poll (default) |
|
|
1 |
Scan immediately |
Important: Some device communication interfaces
support asynchronous polling by default.
These devices include:
|
AB Ethernet |
|
|
Mitsubishi TCP/IP |
|
|
Sharp |
|
|
Triplex |
For these interfaces, if the device response to a poll request is received during the poll after set processing, the response on the poll after set can be processed first.
Do the following if either
condition occurs.
This behavior is observed and is
a problem for the application
Normal polling delivers the data
to the application in a time frame sufficient to meet the
application needs.
Clear the Poll after Set checkbox on the Device tab of the Point Properties dialog box.
If a poll after set is required,
the asynchronous polling can be disabled on the port.
Caution: Disabling
asynchronous polling on a port may significantly alter the data
collection performance.
To disable the asynchronous polling, define the global parameter <PORT>_SYNC_ONLY .
Synchronous polling is disabled by default.
Import/export optional fields.
