Which is the right sintaxis for object name field in Trend Display configuration using 800xA IM Display Services
The Log name configured for this object FT13104 is Log03m15sec, and the following is the configuration for other fields:
Data access: OPCHDA
I assume you are trying with ...\ Infomration Management - Desktop Trends - Trend Display
Steps to open a Tag with Log Configuration in IM Trend Diaplay:
- Open Trend Display
- Click "Browse Objects Icon"
- 800xa structures will appear
- Drill down to tag with log configuration
- use ">" to move the log to "Selected Items"
- Click "Add Traces"
- Be patient after that , it may take liong time to display the trend depending upon the log configuration.
I hope this will resolve your issue.
I've tried to follow the Quick Tutorial on pages 54 thru 64 in the Display Services user's guide (3BUF001093R5021) in a 5.0 SP2 RevE system without making any larger progress.
I get 1-2 points painted in red (=bad quality) and when I debug/log the trend request passed to the 800xA Base system's HDA server I can see that the trend only asks for 8-10 minutes worth of data even though I have tried with scopes of 1h, 1d, etc.???
I suggest that you file a support case at your regional ABB support center.
Finally, I got it to work!
My initial mistake 1:
The default T1_Color property setting is "1" = almost black... you need to choose a better one unless you make the trend foreground color lighter.
My initial mistake 2:
You must change the Update property from "Demand" to e.g. Cyclic_3s.
All of this is actually mentioned in the tutorial on page 57 - "Configure the properties as indicated in Table 7." so I guess I made a RTFM myself... :-)
HINT 1: You can replace the input field with a one shot timer and appropriate code so that you can have the trend to display some trends immediately at callup without requiring any interaction from the user. For some reason I need to call "Update()" or else no traces will be drawn.
HINT 2: Unless you already know, the Information Management Browser tool can be used to retrieve a complete log name into the Copy & Paste buffer.
BTW: My previous statement about logging was a bit incorrect - I misintepreted the logging; the request is there... but it was split into two parts one large and one small and I accidentally thought the last was the only one.
