AccessOPCUA: Subscription of historic AML data responses rounded time stamps
Description
The OPC UA Process Gateway sometimes provides incorrect
timestamps for "Time received" and "Time cleared"
when subscribing to historical AML data. Instead of truncating the last
millisecond, the milliseconds are rounded down. This only occurs with
subscription responses from historical AML data. When reading historical data,
the timestamps are truncated correctly. This causes the timestamps to be
inconsistent between subscription and historical reads.
This error has been fixed. The last millisecond number
is also truncated correctly for subscriptions.
To benefit from this
fix:
- Update your zenon Software Platform to the latest build of zenon 10
or higher.
