DASSidirect connection from SMC to System Platform objects. Frozen values in runtime.

Hi, thank you so much for your reply.

I am using the driver called, ArchestrA.DASSIDirect.3 in the SMC, we also have the possibiltiy to use the OI.SIDIR.1. but we have been sticking to the DASSIdirect.

I am using the OPC object to connect to the application server.

System platform version. 20.1.001 6050.1213.6532.1

It was showing as a solid green box, WITH live values, but the runtime values in application server had not been moving for at least 24h (saw that in historian as a straight line).

Usually when there is a connectivity issue there is some kind of indication in the SMC, like the forementioned red x in the corner, thats why i find this odd.

regarding the logger, could you please guide me to the relevant component, would the DASSIDIRECT component be the only one or also any other that would be interesting to look at?

Also if anyone knows a way to automise through scripting a reset command to the smc connection, It would be interesting to learn,

Thank you!

I am not aware of any way to trigger the Reset feature remotely on a DAServer, what I have done is to stop and start the Service using scripting, witch is almost the same thing, it will restart all connections managed by the driver though, so if you are using multiple connections and only want to restart one of them it might not be applicable for you.

Still I would like to stress that having all values 'freezing' is not common behavior, and needs to be sorted out anyways.

If this is a bug in the version of DASSIDirect you are using (I believe that latest version is from 2018), you could upgrade to e newer driver version, Especially if you are running this on the same server as System Platform 2020, DASSIDiect was replaced by OI SIDIR in 2018 and you should be able to install this instead, but it is of course advisable to sort out what other products are installed on the same server since there might be issues with co-existence of other products.

It will then require that you update your configuration in the OPC Object.

One thing to note, if you download 'the latest' communication driver pack from AVEVA, there are known issues mixing this with older versions of System Platform

I would go for the bundled OI Server from installation media if uncertain of what version to install.
 

I also found this post on the support page

 DasSIDirect topic goes stale and does not update tags 

and this:

 Some items not refreshing with SIDirect 2.0 communication to S7 400 on Ethernet 

It seems similar issue that you describe and points to a bug in older versions of the driver
