Davie Posts: 9 Rating: (0)	I have deleted the HMI from the project and readded but no fix. Indeed the problem remains the same in that three plcs can be accessed over ethernet config all the way down to individual symbols in the db folder and two remain not. I then copied one of the plcs that doesnt work and renamed it. Low and behold I could access it down to symbols in datablocks. I then deleted the plc I had copied and renamed the copy to the original name. Back to square one. It definately looks like some sort of database and the symbolic information is created at the start of the hmi inclusion. This database then remains within the project even if the hmi is deleted. I guess its this database thats corrupt. Any one out there know how to erase this database and start again. Thanx D....

I would be tempted to delete all HMI from the project, Save with reorganisation(slow) and rename the Step 7 project. It may be something simple like a label name tha is being used as a reference. You've proved it can work with a single copied plc so it must be something to do with the whole project set-up.

Davie Posts: 9 Rating: (0)	Guys I'm using an MP277 which can allow up to 6 connections over ethernet. I am only trying to connect 4, so I'm within the limits. I have tried deleting all of the HMI's from the project and then saving as another name with a slow reorganise. Then installed the HMI again but the same result. It was interesting in that the synchronisation of symbols seemed quick, almost as if it was using a saved database or reference chart. I am interested in the addition of MS SQL server as part of the WinCC Flex installation, does anyone know what this is used for with regard to the S7 Project. I am assuming that the 1Gbyte memory and the 2GHz processors are all to do with the SQL server as this is a high spec for an HMI software configuration tool. I will proceed with a few more tests that I have thought of but I feel more convinced that the issue is a database one potentially with the SQL server (I also assume this is a cut down version of SQL otherwise we would need a license and a proper MicroSoft install). Help Davie.

Hi Davie. I'm getting to the bottom of my helpful hints sack! The high spec is partly due to manage the SQL database but I also think the HMI software isn't written very efficiently so every little bit is needed just to get by. The SQL server install is just to manage the WinCC Flexible database but it obviously talks to the Step7 db to make use of theintegration functions. All I can suggest is you send the project to Siemens Hotline to see if they can replicate the behaviour. I have done what your are trying to do with MP277 without trouble(depends on complexity of Step7 project obviously[:D].
