OpcUa_DoCom cost too much time
Posted: 14 Jun 2018, 11:33
Hi, team
I am now using the ANSI C code to do UA communication with Siemens PLC UA Server, during the communication, i found that when i send/recv data as 1 ms cycle time that call SDK UaBase_DoCom() may takes more than 200 ms every step and cause date transfter to PLC with a great delay.
I have tried set DoCom time as 1000 ms which not works well and i wanna ask if there is any setting or method could solve the communication performance
Thanks
Best Regards
