Hello colleagues,

I am developing a project with PCS7 v9.1 and during the process some questions arose. The setup is as follows - 410H with redundant OS Servers, 3 OS clients + ES.

1. When remotely activating a OS server after a full download the runtime starts but after this has happened the activation windows stays open with the "OsStateMachineX.exe" process waiting for something for between 5 and 10 minutes(I haven't measured it exactly). This happens on both OS servers when doing a full download. During this the Simatic Manager is unusable because of the incomplete download process. The runtime is perfectly usable though. This makes the full download a painfully long waiting. What can be the reason this delay?

2. I have configured archiving for objects but every time I open the trend picture of the analog faceplate for example, it starts with showing the tag logs in online mode and when switching to archive mode the trend interval is 1 day. When I switch - all data is there and correcting the time period makes all OK. Is there any orthodox way to make the trend picture to start in archive mode and to set another trend interval to start by default - preferably to be possible to set different times for different POs. I couldn't find anything for this in the Siemens PDFs.

Thank you in advance!

Best Regards,
Nikola Hadjinikolov

I don't know this error. So I can't help you with the. The only advice I can give you is to contact Siemens with a Support Request.

The information to start an trend with the archive values can be found in the manual Advanced Process Library in the section Trend view:

Configuration of the trend view

The trend view can be configured so that archive values are displayed immediately after opening. A prerequisite for this is that archive variables exist. Proceed as follows:

• A "1" is attached at the block icon in the "TrendPictureName" property. A semicolon is used as the separator to the name of the trend view.

  Example: @pg_apl_trendPID_Statistic.pdl;1

HI Nikola

1. I can't fully answer this question, as I don't know that I've specifically seen OSStateMachineX be the reason for slow restart, but in general we don't use the auto download on Server projects as a hold over from a time when OS downloads weren't so stable. As a habit when performing full downloads for any of our customers we normally stop runtime manually on the OS server, perform the full download and restart runtime manually.  I know you aren't supposed to have to do this, but it avoids having the ES tied up for that whole time.  Don't forget you have to wait for servers to finish syncing after the complete download no matter which method.

If you really want to get to the bottom of it instead of just dealing with the problem like we eventually have, then I agree SR is your best bet.

2. +1 for Heisenberg's answer.

Hello again,

Thank you both for taking the time to answer my questions!

1. After this post the first thing will be to make a request for support.
In the mean time I do the same - I deactivate manually, download and activate manually. I have never had any problems on full download. Sometimes "Download changes" jams up and after that I need to make a full one.

2. Now I feel stupid because I searched through this PDF, but searching for "tag logging" was not the right thing to do and I realize this just now as I read your replies... Tomorrow morning I will use this :)

Thank you again and if Siemens give me a solution I will write it here, so if anyone other has the same issue - he can see this :)

Best Regards,

Nikola Hadjinikolov
