Hello everybody, I'm working on my very first WinCC flexible project at the moment. I have an S7-400 H system with a lot of fault-tolerant connections. Everytime the connection status changes, the connection ID, timestamp andthe statusare stored in a STRUCT in a DB. This DB has an array with 500 elements containing the STRUCT. On my panel I want to display 20 of these 500 array elements in a table. By using different buttons during runtime, the user can decide which array elements are displayed. I use the FAQ How can you have data from a tag log displayed in table form for panels or the WinCC flexible PC Runtime?as a basis for my implementation. The example provided in the FAQ contains several scripts. In these scripts I found the command "ShowSystemAlarm". I want to use this command to show errormessages to the user and to be able to debug my implementation. I tried to use the command in my script and expected to see a message on my panel, but no message was shown. Does anybody have an idea what can be the reason for that? How long is the message shown on the panel? Maybe it is only shown for a very short time and I missed that? Since I never used WinCC before and I barely know VB,I make a lot of mistakes and I really need a way to debug my script at least a little... Regards, Sakura |
