Log configuration for real variable
I am using 800xa system i want to configure log configuration for real tag without using signal in real block. i tried in control structure but no option for configuration log for real variable. Please help.....thanks in advance..
SignalInReal and log configuration are completely unrelated. You can configure log for any variable.
you just need to...
1) Add the "log configuration" aspect on the object where the variable is defined.
2) use "Add Property Log" option to browse the vaiable name
3) choose an appropriate log template.
(ofcourse, history source configuration needs to be done as well.)
Refer manual for more details.
First the log configration needs to be created in Library structure specifying the time interval at which you want to log the values.
then based on this configuration a "Log Configuration" asect needs to be added either in control structure or you can create it in object type structure also.
