The device connection overload is excessive

[zhao_zi]

In the project, I need to connect the new Siemens 1500plc to read and write data. In this process, I encountered some problems. I only added 372 points, but overload reached 161% and the writing delay reached 3129ms, which was the result after I increased the polling rate to 1200ms. Normally 372 points wouldn't be such a high overload, would it?

What are the factors that affect overload? What should I do next?

Do you work with @vincent.hu ? That exact graphic was posted and this question was asked over here:
