We are upgrading our system from RHEL 8.4 with OA 3.18 Patch 4 to RHEL 8.8 with OA 3.18 Patch 24. After upgrading the OS and OA we could no longer login to OA using domain accounts. We were able to resolve this by adding the additional entries to the /etc/pam.d/wincc_oa file as found in the online h...

This is a bug with the S7+ Driver. It was fixed in WinCC OA 3.18 Patch 24.

We seem to have come across a bug or limitation of the S7+ driver. When there are a small number of tags and we disconnect our S7-1500 PLC the driver picks up the comms failure in a reasonable amount of time (less than 20 seconds). However when we have a large number of tags (more than 20,000) doing...

We are running WinCC OA v3.18 Patch 4 on RHEL 8.4 On some occasions when removing a symbol via the removeSymbol() function the vision crashes and produces nothing in the WinCC OA log viewer.

Great thanks Leopold! That worked as desired

The Tree widget provides the ability to add checkboxes to the items in the tree via the 'setCheckable' function. When this is set on the parent and child items in a tree the parent checkbox will check and uncheck the child items. This behaviour is fine if all the child items are enabled. However whe...

Hi Herbert, Would this be considered a high priority bug? Just wanting to gauge how long we have to wait before a patch is released. Unfortunately we already have a production system connected to a domain with such usernames so in the meantime we will have to implement a temporary work around to acc...

We're using OS Authentication and the domain accounts use the following username structure: <firstname> . <lastname>, eg my user is eric.maddocks on the domain. When logging in OA doesn't complain or advise that this will cause issues. Even when creating users locally and including a period '.' in t...
