I'm using ano-bells,no-whistlesinstall of WinCC 6.0.3.0 on the customer's Server machine

I need to 'slow down' the script just before triggering the message so that it contains the correct values. Salma suggested a For-Next loop for this purpose. ps. The Customer has strict control over what is installed on their PCs, so I don't haveExcel or ODK (whatever that is)

Reuben Posts: 70 Rating: (13)	Hi I had this same problem trying to do the same thing. I was trying to log a message like "Joe Soap has changed Setpoint XYZ from 10 to 20" and had all sorts of problems. The "built-in" functions never seemed to work as advertised so this is what I ended up doing: 1) Wrote a function with ODK to manually generate an alarm message (no triggering with internal tags - this is where you end up one message behind) 2) Put some code in the "Focus Change" and "Output Value Change" events of IO Fields to call this function when the operator edited the value. In the "Focus Change" event the script stores the output value of the IO Field into a static variable; in the "Output Value Change" event the script uses this previous value and the new value to log an alarm message. You can get the Create Alarm function with explanation here: http://www.allottware.co.za/raweb.dll/Script?p=Alarms&s=raCreateMessage You can get the function to call in the IO Field events here: http://www.allottware.co.za/raweb.dll/Script?p=Alarms&s=raCreateValueMessage I haven't looked at this problem in a long time, and I don't know how this works in a Server/Client situation. The script also does not work through WebNavigator. Reuben

I have tried chaining scripts together, and calling Project Functions. The rare occations thatthe event message contains the right dataI have to right off as flukes. I have tried a couple of other 'delay tactics', but these either simply don't work or tie the script engine up in knots. I need a reliable method of ensuring the message captures the correct data.

Reuben Posts: 70 Rating: (13)	Hi The ODK is the "Open Developer Kit", and is simply a help file that explains the open API functions available in WinCC, which can be used either in WinCC C-Script or fromexternal applications (it is not an "add-on" for WinCC). The scripts will work regardless of whether or not the ODK is installed. It should be stated that misuse of "ODK" functions can cause problems in the stability of the WinCC system, which is why they are not generally recommended. Reuben

I had a few problems getting the call to the function to compile (the PV variables as used in your example caused headaches) and I can now generate messages. The only problem is, they appear as they do in the Alarm Logging window (complete with @xx@ controls), and I can't seem to find a way to turn the messages 'off' again (the same message may be triggered more than once). Thanks in advance for your assistance.
