### What happened? I'm writing a program in plc4c for use in an industrial production environment. Now I have a problem. When there are many tags in a request, there will be no response. I have encountered a similar situation when I used the early version of plc4j, maybe it is pdu and division? Please give some advice, thanks a lot. @christ I used wireshark to capture packets, but I couldn't upload the relevant attachments because github does not support the relevant attachment types, the screenshot is as follows. Let me know if any information is needed and I will do my best to provide it  ### Version v.0.10.0 ### Programming Languages - [ ] plc4j - [ ] plc4go - [X] plc4c - [ ] plc4net ### Protocols - [ ] AB-Ethernet - [ ] ADS /AMS - [ ] BACnet/IP - [ ] CANopen - [ ] DeltaV - [ ] DF1 - [ ] EtherNet/IP - [ ] Firmata - [ ] KNXnet/IP - [ ] Modbus - [ ] OPC-UA - [X] S7 -- This is an automated message from the Apache Git Service.
