[?]: TP 270 - Tag Change Method

[peterg70]

Does anyone have an example for creating a logfile to detect the change in tags on the screen.
Something like

Code: Select all

11:20 AM 01/05/2013 - Tag MOTOR_SPEED_SP changed from 200 to 100

Also need change in state of buttons etc.
Something Like

Code: Select all

11:20 AM 01/05/2013 - Tag MOTOR_AUTO changed from 0 to 1

The TP270 is a windows CE panel so would need to store the logfile in the MMC etc.
Also how to display this logfile back on the screen.

I only need the last 200 changes or entries put into the logfile

Couldn't find an example for my option.

I am sure I have seen a script which is executed on the change value function that adds a message to the alarm log with a different class.

I.e. Alarm log with new class called LOGENTRIES
then call function with tag name etc on Change Value option.

Not sure if it could post the OLD and NEW value to the Alarm log.

Then changing the alarm class on the alarm window it will show the logentries.

I am sure I saw it on siemens website but I can't find it again.

Anyone have any links for the above options.
