Hi all!

I've new pc station which I try to connect to siemens s7-400 plc.

I've made a copy of the wincc project of "old" pc station (with project duplicator tool) and open it at new pc station.

New pc station is configured in simatic manager (hw config, netpro), .xdb file is imported to new pc.

"Old" Simatic PC Station 1 (HMI) based on "s7_connection_1" and "s7_connection_2" named connections

"New" Simatic PC Station 2 (PC) based on "s7_connection_3" and "s7_connection_4" named connections

The problem is that when I'm trying to set new named connection (s7_connection_3 or s7_connection_4) on new pc station 2 (in tag managment) I've got an information "the connection is read only". I can select only "s7_connection_1"

Can You advise what can I do to solve this problem?

Please look at attached files.

Kind regards,

Jakub
