Hello,

I need to change router IP address in a PLC CPU configuration, but when I search the node and try to do any change in the node configuration (router address, node name etc) I receive error message “The function could not be executed” and error code 4502:529. Other functions are working – I can access the node, see properties or download, run and test application. Before the function worked from the same computer – few days ago I configured it. I also can’t find any specification of error codes. Working with CPU 315F-2PN/DP and S7 Manager V5.4+SP3.

Thanks in advance.
