POLL_AFTER_SET

Point Type Device
Maximum Field Length Boolean
CIMPLICITY Field Name Poll After Set
Description Determines if polling should be done after a setpoint.
Values 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.
Note: 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.
