此异常最初是在此调用堆栈中引发的:
S7.Net.Plc.ValidateResponseCode(S7.Net.Protocol.ReadWriteErrorCode) (位于 PLC.cs 中)
S7.Net.Plc.AssertReadResponse(byte[], int) (位于 PLC.cs 中)
S7.Net.Plc.ReadBytesWithSingleRequest(S7.Net.DataType, int, int, byte[], int, int) (位于 PlcSynchronous.cs 中)
内部异常 1:
Exception: Received error from PLC: Address out of range.
