Hello,

if I could ask you for sure because your question is little bit confusional to me, not depended to exact problematic. You mean, you want to have some existed cfg on PLC to not be changed from outside (from web server)? sry but I can't imagine now what exactly service you are afraid of. I don't know, easy step is set security credentials on internal Webserver of PLC, or?

 

Hello Dear, 

Sorry for the confusion, I have a configuration for the MRP which are not able to be done via the TIA portal and should be done from the webserver. 

When we are installing the program on the PLC it is going to overwrite the settings that we already done from the webserver. 

So we need a method to prevent the PLC from overwriting the configs in the XC-206

Select the XCs in TIA

PROFINET interface [X1] > Advanced Options > Media Redundancy

Enable the checkbox for "Alternative Redundancy" 

Load the PLC
