Hello,

I have a problem when calling a fc with many input parameters. I get the message 604:240. Look at the picture below - capture from help:

Normal 0 21 false false false SL X-NONE X-NONE MicrosoftInternetExplorer4

I have declared 47 InOut parameters - 1280 bytes. when I set it to less (e.g. 20) it works fine. I am using S7-1515. Can someone tell me what is the upper limit for InOut variables? If I put some of the parameters in the IN or OUT parameters, will it be possible to use more parameters of the function?

Thanks for your help,

Best regards

Lesko

Try to use an UDT as Parameter.

The UDT can encapsulate a large amount of parameters.
