最佳答案
出现“Overload sender”报警，可能原因：
- To much data
- To fast OB --> It is necessary that he use a slower?sender then a receiver. This means you have to control that the sender is in a slower OB or the same as the receiver.?
- Also the CPU Settings should be upgraded. The option "Scan cycle load from communication" can upgraded to 30%
