|
Parameters |
Description |
|---|---|

|

|
Mreaidx Poll Rate |
Defines the poll rate for AVEVA Batch Management with Foxboro DCS components updates. The actual poll rate is the Mreaidx Poll Rate value times Read
Scan Rate value. The result is in milliseconds. |
|
Unlinked Tag Warning |
Enables detection and logging to Batch Logger when tags are not linked. The default is False. |
|
Unlinked Tag Ignore |
When this option is enabled, tags that are not linked are not created by FoxDCSDriver. This allows other tag servers, such as SimMngr, to have the opportunity to create and service those tags. Be careful when using this option because unlinked phase or batch control tags that are controlled by a simulator (that is, SimMngr) can cause unexpected results in a production system. The default is False. |
|
Max Precision |
Enables the maximum available resolution for tag values. |
