The picture below is the result that I have tested. I only want to read all data in the "table" array and print them in Output Console. But in my code, it doesn't work.

I think its a matter whether FlexSim's OPC UA Client support array datatypes. I never met 3DSimulator which supports arrays. Nothing is mentioned in FlexSim online manual.

If array is not supported, you will need to breakup the array to datatypes(bool, integer, etc.) within OPC server and then send to FlexSim.

Hi @Apollo S,

The print() command doesn't print to the little output field in the script console. That is just for the return value from the code. The print() command prints to the Output Console. Have you checked to see if the array is replicated there?

I hope this helps! Let us know if you have further problems/questions!

I have checked. The Result in Output Console is 0. I can't get the array.
