Re: WINCCOA 3.20 Communications Failure

In most of the cases in WinCC OA a datapoint is created for a PLC connection. At this datapoint you will find DP elements which provide the information for the connection status. Here is an example for the S7 driver: https://www.winccoa.com/documentation/WinCCOA/latest/en_US/S7_Driver/topics/s7_inte...

Re: bar trend - curve type axis

Why are you using a bar trend if a curve is shown then?
Why not using a normal trend in this case?

Re: Alternative to timed functions

For cyclic tasks the timed function was implemented. A timed function can also be used for tasks which must be executed in short intervals, e.g. 10 or 30 seconds. More interesting is the question why you must update the number of alerts in a short interval? Where is the information for the number of...

Re: CNS node types icon path not loaded

I have compared the functions cns_getNodeTypeDisplayName(), cns_getNodeTypeValue() and cns_getNodeTypeIcon(). They work different. While the first 2 mentioned functions work more or less as stand alone functions the third one has some prerequisites. The prequisite is that the mappings which are used...

Therefore, the function does not return a value if the panel was not loaded. Where do you want to use the information for the CNS icon? Best Regards Leopold Knipp Senior Suppo...
