Openig a project, 2 errors pop up.

Server "wcf_appx.dll" for objects  _S7H_CLASS_PC_UTAH_APPL_CT has not been loaded..

Server "s7wnfcx.dll" fpr objects  _S7V_CONN_TCP_RFC1006_CT has not been loaded.

Hola,

It appears that you have a project in Step 7 v5.x (Simatic Manager) that included certain packages that are missing in your installlation

- wcf_appx.dll is a file reuired for an imbedded WinCC Flexible RT program, used to setup an HMI stationlinked to the PLC program.

- s7wnfcx.dll is linked to ISO on TCP/IP communications on a S7-300, it is possibly related to ISO services not launched, or a missing CP 1612 card in the PC...

Are you working with an uploaded Step 7 project, in which case the WinCC Flexible part of the project are missing?

If the WinCC Flexible project was embedded in Step 7, you could try removing the embedded project from the  Step 7 program...

Hope this helps,

Daniel Chartier
