Information management configuration
my sytem include a redundant ASCS with two IM servers.all installation and post installation had been done according to manual and PAS services are running.
to use Information managment I have following question.it should be mentioned the IM server has added as connectivity server.Is it Correct?
1.what is difference between history source and inform IT history object?the history source is connectivity system or IM server?please clear me in this matter.
2-Log template is a trend log as direct with OPC source and IM History log with trend source with IM node server as service group.I want to know that when IM log become active,where does data store and how to retrive the stroage data?
3-To use stored data in report with desktop tools like data direct how can I can call them?is it done by inform IT version in data direct as history values?
4-what is the data direct login data in excel ?I cant connect and face with error "could not find host".
your answer would be high appreciate.
Thank you so much.
Answer to each point:
1. Yes, IM servers will be added to the system as connectivity servers.
2. history source ia an aspect (not object) used to specify the service providers to collect the data. Make sure the history source is pointing to the service provider (in this case connectivity server (CS)) which is the data source.
Inform IT history object in the node administartion structure provides the log set, control aspect and message log services and configuration.
3. Trend logs will be stored in connectivity servers (as defined in the history source), and IM log data will be stored n the IM servers.
4. Using the datadirect, all you should know is the correct log template. While retrieving the the history data select the respecting log name that will fetch the data from respective source. For ex. if you select trend log name, it will retrieve the data from CS.
5. I believe, by default, it is "aid"
Some additional information to the questions asked in the comments to the previous answer.
1. IM require Basic History to perform primary logging. Basic History uses History Source to point to the Connectivity Server / Service Group within Basic History that should do the primary logging.
2. IM adds as Connectivty Server; becomes with an own IM_BasicHistory service group to which no History Source need to point to. The IM_BasicHistory service provider is necessary for the OPC HDA Collector link between 800xA and IM to work.
3. IM becomes engaged to perform secondary logging (on top of Basic History primary log) when Log Template is adding a IM History Linked Log. IM service group must be chosen.
4. IM can log at same sample rate as primary log, e.g. Basic History 1s/1week -> IM History 1s/10years, or perform some aggregate, e.g. Basic History 1s/1week -> IM History 1minute average/10 years.
5. IM logs are created inactive and need separate activation. Per log at the Log Configuration aspect, or many logs at same time from IM Log List in Node Administration Structure.
6. Retrieval of OPC HDA data to Excel / DataDirect does not need any account/license or login. The ABBGetOPCHDA() macro is free to use on any 800xA node in the system. Remotely located Excel / DataDirect sessions *REQUIRE* an EXCEL_DA license seat and login to the IM server. There is no default account nowadays, but on disk there is the old account sample file that can easily be moved into location on the AID Server. The old (default inactive) account name were "aid" with same password. New password can be easily set with tools belonging to AID server. Read the IM Configuration User's Guide, then the IM Data Access and Reports User's Guide.
7. The orange warning border seen in alarm lists/bands/etc when IM is offline can be removed by clearing the "Significant Alarm Source (gives visual notification)" checkbox on the IM OPC AE server's Alarm Collection Definition->Config View in the Library Structure (ABB Hs OPC Alarm Event Server). Restart the Event collector to have the new setting to take effect. Such inhibit of alarm system malfunction is NOT recommended for A&E sources vital for the process control / operation. I consider the IM A&E source to be of no importance for the operator, only system engineer when troubleshooting IM.
