Processanalyst an Classic Trend dosent display data

Fredric Johansson

Hi!

Please advice on a strange behaviour.

Processanalyst (and classic trend page) can see all trendpens and its possible to seek in trend database.

But it dosent display any data. It was working until i added a new cluster and attached a new alarmserver (not trend). Ive mowed a nnuber of alarms to the new cluster because the alarm process (32 bit) exeeds memoy limit and the alarmserver cant run in 64bit mode because it uses a 3rd party 32bit dll. I think my trend problem happend upon adding the clustered alarm server but not sure. Its 2023R2 and the project is currently in migrationprocess from Citect 7.50.

The new alarmserver in an new cluster works on all clients so no problem there.

In page table tran all processes are OK and connecterd.

Best regards Fredric

     Hi  ,

    It looks like configuration related. Is the project a single cluster system before a new cluster is introduced for alarms?

    Take a look at syslog.dat and syslog.trend.[cluster].[alarm server].dat and hope you could find some useful information. Meanwhile, launch the kernel window of the client process and see if the trend servers are connected.

    Hi Jacky, it seems like the trend servers are connected as it should, the client also gets the trend pens from the server.

    And yes, ive added a new cluster to a former one cluster solution, only for alarms.,

    Ive launched some logging, debug option 16 in trend debug, but it says not much (not to me anyway):
    2025-09-12 08:37:29.089 +02:00 Trend: trnCli : msg type 0xf01

    The server says (debug option 7):
