Applies to:
PcVue 16.3.0, PcVue 16.3.1, PcVue 16.3.2
Summary:
This is a known issue discovered thanks to SPR #76089 and 75445 in version 16.3.2
Fix planned in 16.3.3
Details:
Since 16.3.0, BACnet COV re-subscriptions are not handled correctly, leading to a situation where BACnet variables are no longer monitored nor refreshed. Because the issue is related to re-subscription, it becomes obvious only after some time, once a re-subscription is necessary (typically 1 hour).
Recommendation:
A workaround exists. The issue does not exist in the legacy COV implementation. While it is no longer the default, it can be re-activated by adding the following key in the Etc\experimental.ini file:
[BACnetStackCov]
Enabled=1
